Fake SFP and the Third Party SFP

It appears to be an old topic that whether using compatible SFP transceiver is reliable. We have previously discussed this topic couple of days ago. For certain, the reply is affirmative. In this paper we discuss Faked SFP and the Third Party SFP. As examples, there are Cisco SFP module and Brocade SFP module.

It Is A Faked SFP?

Like a break pad an SFP is somewhat a consumable. Light is converted into an electric signal and vice versa, produces heat and the components wear out over time. Some sooner, some later. When you bought the SFPs from Cisco for a switch under Cisco warranty or maintenance, broken SFPs will be substituted for free. However, if you simply decide to purchase an SFP, you will find after having a quick web search that there are lots of supplier out there providing the same SFP for a much cheaper price than Cisco. And with "the same SFP" I mean they provide exactly the same Cisco part number - for example Cisco GLC-SX-MM. That's an 1000BASE-SX SFP 850nm 550m transceiver.

Really The Same SFP?

Absolutely not - even though they claim it to be the same. Their usual explanation is, that all these SFPs are coming from the same manufacturer anyway. SFPs are built using open standards based on T11 and for that reason they must be compatible per se. I can tell from several occasions: That's not true. There is obviously more than one SFP manufacturer and I'm sure each of you know a handful offhand. In addition: Even in times before 8G there were SFPs working much better with certain switches than others.

Utilizing the 8G platform Brocade decided to offer Brocade branded SFPs and restricted their switches to only support them and to refuse others (beside of very few exceptions for CWDM SFPs). So Brocade took control over which SFPs can be used and they were able to fine tune their ASICs to allow better signal handling and transmission. To enforce that the switch checks the vendor information from the SFP to determine if it's a Brocade branded one. Cisco does the same thing for the SFPs in their switches.

Faked SFP vs Third Party SFP

First, we must realize that Third Party SFP isn't faked SFP. If you are seeking further savings on your own network, consider Third Party SFP. When you purchase from a vendor with their own in-house shop, and guaranteed warranty, you get a purchase that's as reliable as new, at a fraction of the original costs. In my opinion, if you have enough budget, It is best to buy the original one. It doesn’t mean that the compatible one is as not good as the original one but you could save more time in thinking about this question. If you care about the cost, compatible one is the best choice, I suggest you choose the OEM manufacturers.

Fiber Optic Transceivers Today and Tomorrow

Fiber optic transceivers is a self-contained component that can both transmit and receive. Usually, it is inserted in devices such as routers or network interface cards which provide one or more transceiver module slot, such as GBIC module, SFP transceiver, XFP, etc.

Fiber Optic Transceivers Today

Fiber optic transceivers for applications in the field of datacom are mostly characterized by a couple of established international standards. These standards define the electro-optical performance of a transceiver/transponder as well as its pinout and its physical outline and package, including the corresponding fiber optic connector interfaces.

Fiber optic transceivers meeting these standard are operating worldwide in numerous applications in mainframes, server clusters, storage area networks, wide area networks, and local area networks, and currently around 20 to 30 worldwide competing suppliers have been established. The number of partners involved in some important multisourcing agreements has seen an increase since 1989. This is also indicative of the increasing importance of industrial associations where both suppliers and applicators are represented. This speeds up the market penetration of novel components, systems, and applications. Nowadays, this does not seem to generate conflicts with the commonly agreed normative power of international standardization organizations such as the Internationnal Organization for Standardization (ISO), International Electrotechnical Commission (IEC), and International Telecommunication Union (ITU).

The demand for these transceivers has continuously increased during the past 10 years, and the prices have shown dramatic decreases of order of 25% per year. Consequently, the goal of all manufacturers is to offer a high level of performance, reliability, quality, and serviceability while maintaining cost-effective production in the face of drastically increased volumes to meet the market pricing.

Some Aspects of Tomorrow's Transceivers

The bit rates of fiber optic transceivers are continuously increasing in order to meet the worldwide demand for ever higher bandwidths. These bandwidth increases are called for by both existing storage and networking markets, as well as the parallel computing industry and high end server design.

In the past 10 years, a significant reduction of transceiver module size was possible due to significant progress in the downsizing of optical subassemblies and associated passive and active electronic comparison of the ESCON/SBCON outline, multistandard, small form factor (SFF), and parallel SNAP-12 transceivers. The function of the transceivers shown is described in detail in my previous blog posts.

Future transceiver design is likely to focus on power consumption, electromagnetic compatibility and immunity, and density. As data rates continue to increase, we will start to see transceivers used closer to the ICs on the board and not just at the card edge. It has also been demonstrated the is possible to incorporate optical components onto a chip, completely avoiding the deficiencies of high-speed signals on copper board traces. While these advancements may take their place in high-end computing systems, classical card edge transceivers are likely to continue to play their role into the foreseeable future to allow fiber cable connection for SANs and networking.

Where to Buy Fiber Optic Transceivers

Fiber optic transceiver is a very popular format that's recommended by a large number of fiber optic component providers. Fiberstore provide a full range of optical transceivers. Cisco, especially, you can find a full product line of our New Cisco SFP modules, such as GLC-T SFP, SFP-GE-T, GLC-SX-MM, etc. Our SFP and SFP+ moduels are 100% compatible with a good price and enjoy same-day shipping.

What is the difference between GLC-T and SFP-GE-T?

What is the difference between SFP-GE-T and GLC-T? I have some information from Cisco Support Forums:

• GLC-T, 1000BASE-T SFP transceiver module for Category 5 copper wire, RJ-45 connector.


• SFP-GE-T, 1000BASE-T SFP transceiver module for Category 5 copper wire, extended operating temperature range, RJ-45 connector

GLC-T 1000BASE-T SFP, which is a fiber optic transceiver module via Category 5 copper lines, Cisco GLC-T fiber transceivers provide 1Gbps data transfer and it provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over existing copper network infrastructure. GLC-T SFP is compliant to IEEE 802.3 and its dimension is 0.6 in x 2.8 in x 0.6 in. GLC-T is with plug in module type Mini-GBIC.

3rd-party GLC-T Key Features

• Support 1000BASE-T Operation in Host Systems


• For 100m reach over Cat 5 UTP Cable


• Hot-Pluggable SFP Footprint


• Support RX_LOS as Link indication function


• Fully metallic enclosure for low EMI


• Low power dissipation (1.05 W typical)


• Compact RJ-45 connector assembly


• Compliant with SFP MSA and IEEE Std 802.3-2002


• Detailed product information in EEPROM


• Commercial temperature range (COM): 0 to 70°C

Cisco SFP-GE-T works with 1000BASE-T. SFP-GE-T is with extended working temperature and it is with DOM support. SFP-GE-T is small form transceiver with RJ45 connector interface and it is with spring latch for high density applications.

3rd-party SFP-GE-T Key Features

• Support 1000BASE-T Operation in Host Systems


• For 100m reach over Cat 5 UTP Cable


• Hot-Pluggable SFP Footprint


• Support RX_LOS as Link indication function


• Fully metallic enclosure for low EMI


• Low power dissipation (1.05 W typical)


• Compact RJ-45 connector assembly


• Compliant with SFP MSA and IEEE Std 802.3-2002


• Detailed product information in EEPROM


• Commercial temperature range (COM):0 to 70°C

The third-party GLC-T and SFP-GE-T have the same Key Features. So no difference between them? I think that they are operationally identical and can be interchanged with no problems - the only difference is that the SFP-GE-T conforms to NEBS Level 3 and the GLC-T doesn't. And Then question is what is NEBS Level 3? I'll also add that the SFP-GE-T is a little bit more expensive...maybe $40 more (retail) but it works in switches or routers like the ASR while the GLC-T is for switches only.

What is NEBS and why is it important?

Long a requirement for equipment used in the Central Office in the North American Public Switched Network, the rigorous Network Equipment Building System (NEBS) criteria have become a universal measure of network product excellence. The NEBS compliance of GDC's products is a key advantage for access providers including Local Exchange Carriers (LECs), Competitive Access Providers (CAPs), Competitive Local Exchange Carriers (CLECs), Internet Service Providers (ISPs), and Access Service Providers (ASPs). Products that are NEBS certified are also expected to be top performers in enterprise net- work environments as well.

What does NEBS Level 3 Certified mean?

NEBS has three levels, Level 1, Level 2, and Level 3. Level 1 refers to cases where minimum compatibility with the environment is needed. Level 2 applies for limited operability of the product. 

Finally, NEBS Level 3 certification guarantees the maximum operability of the equipment. It also certifies that the equipment will perform well in harsh environmental conditions and will not interfere with other electronic devices around. NEBS Level 3 certified networking equipment is vital in mission-critical applications. More information about NEBS please Google it.

In a word, GLC-T with 1000BASE-T standard, SFP-GE-T with 1000BASE-T NEBS 3 ESD. But, for a 3rd-party SFP module, I still don't know what the difference between them.

FAQs about HP Mini-GBIC and SFP Transceivers

Q: Which ProCurve Mini-GBICs and SFPs are supported in which ProCurve products?

The ProCurve Networking Mini-GBIC Support Matrix specifies which Mini-GBICs and SFPs are compatible with which ProCurve products. General rules are:

• Only genuine HP Mini-GBICs and SFPs are consistent with HP products.


• The J8177B/C 1000Base-T Mini-GBIC is not supported in "dual personality" ports (which already include a gigabit copper LAN port).


• Newer ProCurve / ProVision products require revision "B" or later Mini-GBICs and SFPs (product number ends with the letter "B" or later, for example J4858B, J4859C).

Q: Are the "revision C" Mini-GBICs (J4858C, J4859C, J4860C) supported in all products that support the "Revision B" (J4858B, J4859B, J4860B) Mini-GBICs?

Yes, the "revision C" Mini-GBICs (J4858C, J4859C, J4860C) are supported in all ProCurve / ProVision products that support Mini-GBICs.

Q: Can I mix and match "B" and "C" mini-GBICs in a ProCurve switch?

Yes, "Revision B" and "Revision C" mini-GBICs can be used together in any ProCurve switch that supports mini-GBICs.

Q: Are the Mini-GBICs and SFPs hot-swappable?

Yes, all HP Mini-GBICs and SFPs are hot-swappable (they can be installed and removed while the switch is powered on). However, the network cable should be disconnected before removing the Mini-GBIC or SFP from the switch.

Best practice tip: After inserting a transceiver into a ProCurve / ProVision switch, the Mode LED will come on for two seconds while the transceiver is initialized. Do not remove the transceiver until the Mode LED has turned off. For the Switch 2600 and 2800 Series: After inserting a transceiver into a 2600 or 2800 switch, the "M" LED will come on to indicate that the mini-GBIC slot is active. Wait at least two seconds after the "M" LED comes on if you need to remove the transceiver.

Q: Which HP Mini-GBICs and SFPs are RoHS compliant?

All currently-shipping HP Mini-GBICs and SFPs are RoHS compliant. This includes:

• J4858C HP X121 1G SFP LC SX Transceiver


• J4859C HP X121 1G SFP LC LX Transceiver


• J4860C HP X121 1G SFP LC LH Transceiver


• J8177C HP X121 1G SFP RJ45 T Transceiver


• J9054C HP X111 100M SFP LC FX Transceiver


• J9099B HP X112 100M SFP LC BX-D Transceiver


• J9100B HP X112 100M SFP LC BX-U Transceiver


• J9142B HP X122 1G SFP LC BX-D Transceiver


• J9143B HP X122 1G SFP LC BX-U Transceiver

Q: When should I use the "auto-100" setting for my J8177C gigabit-copper Mini-GBIC?

The J8177C "auto-100" setting is helpful in connecting an 8200zl or 5400zl switch to an Avaya Cajun switch or Avaya G700 Media Gateway (PBX), which operate at 100 Mbps and send non-standard Ethernet preambles. Because of the non-standard preamble, those Avaya products send packets that the Switch zl 10/100/1000-T ports do not recognize. With the "auto-100" setting, the J8177C will operate at 100 Mbps, will auto negotiate the duplex and flow control, and will accept the non-standard packets. (NOTE: The "auto-100" setting can be used for only J8177C products, not for the J8177B.)

Q: What products do not support the J8177C but do support the J8177B?

The 9300m and 9400sl products do not support the J8177C version. Other than the 9300m and 9400sl products all other products that support the J8177B version will support the J8177C version.

Q: Where to buy compatible HP Mini-GBIC and SFP transceivers?

Connecting the Transceiver

Tips: Optical SFPs use a small laser to generate the fiber-optic signal. Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Keep the optical transmit and receive ports covered whenever a cable is not connected to the port.

Connecting the MFEBX1, MFEFX1, MFELX1, MGBBX1, MGBLH1, MGBLX1 and MGBSX1

Step 1 Insert the mini-GBIC SFP module with the printed side up and the rubber port cap facing out.

Step 2 Remove the mini-GBIC SFP module's rubber port cap.

Step 3 Connect the fiber cable’s LC connector to the mini-GBIC SFP module’s port.

Step 4 Connect the other end of the cable to an SFP module to verify that the fiber connection is complete. For the Cisco MGBBX1, use the Cisco GLC-BX-D as the downstream SFP. For the Cisco MFEBX1, use the Cisco GLC-FE-100BX-D as the downstream SFP. The Cisco MGBBX1 and the Cisco MFEBBX1 support upstream only.

Removing the Transceiver

Step 1 Press the fiber cable’s connector and pull to remove the fiber cable from the mini-GBIC SFP module.

Step 2 Pull the module’s bail latch down.

Step 3 Remove the mini-GBIC SFP module.

Removing the MGBT1

Step 1 Press the RJ-45 connector’s tab and pull to remove the cable from the gigabit SFP module.

Step 2 To remove the gigabit SFP module, begin by pulling the module’s pull tab.
