The Recognition of Optical Transceiver

Optical Transceiver Overview

What is an Optical Transceiver Module?

A fiber optical transceiver is a device that can send and receive optical information. By using an optical transceiver, network spend less space and steer clear of the necessity of getting a transmitter and receiver in the network. Able to transmit information further and faster than older models, the more recent transceivers are utilized and appearance, creating more compact, smaller sized modules than ever before.

How does it work?

A fiber optic transceiver is a accessory acclimated to forward and accept optical information. There are a number of different components on these devices, including a light source and an electrical component. The transceiver has two ends, one that an optical cable plugs into and accession for abutting an electrical device. Fiber optic transceivers combine a fiber optic transmitter and a fiber optic receiver in a single module. They are arranged in parallel so that they can operate independently of each other. Both the receiver and the transmitter have their own circuitry and can handle transmissions in both directions. In fiber optic data links, the transmitter converts an electrical signal into an optical signal, which is coupled with a connector and transmitted through a fiber optic cable. The light from the end of the cable is coupled to a receiver, where a detector converts the light back into an electrical signal. Either a light emitting diode (LED) or a laser diode is used as the light source.

Principle of Optical Transceiver Modules

Optical transceiver generally includes both a transmitter and a receiver in a single module. The transmitter and receiver are arranged in parallel so that they can operate independently of each other. Both the receiver and the transmitter have their own circuitry so that they can handle transmissions in both directions. The transmitter takes an electrical input and converts it to an optical output from a laser diode or LED. The light from the transmitter is coupled into the fiber with a connector and is transmitted through the fiber optic cable plant. The light from the end of the fiber is coupled to a receiver where a detector converts the light into an electrical signal which is then conditioned properly for use by the receiving equipment.

Application of Optical Transceiver Modules

Optical transceiver, essentially just completed the converted of data between different media, can realize the connection between two switches or computers in the 0-120km distance. Its main function is to achieve the conversion between optical-electrical and electrical-optical, including optical power control, modulation transmission, signal detection, IV conversion and limiting amplifier decision regeneration. In addition, there are some functions like security information query, TX-disable. Here is a summary in the practical application.

1. Optical transceivers can interconnect with switches.


2. Optical transceivers can interconnect between the switch and the computer.


3. Optical transceivers can interconnect with computers.


4. Optical transceivers can act as the transmission repeater.
   When the actual transfer distance exceeds the nominal transmission distance of the transceiver, in particular, the actual transfer distance exceeds 120km alerts, with 2 sets transceiver back to back in the case of on-site conditions allow, repeaters or the use of "optical-optical" conversiona relay, is a very cost-effective solution.


5. Optical transceivers can offer conversion between single-mode and multimode fiber connection.
   
   When the networks appear to need a single multimode fiber connection, you can use a multimode transceiver and a single-mode transceiver back-to-back connections, which can solve the problem of single multimode fiber converted.


6. Optical transceivers can offer WDM transmission.
   
   The lack of resources of long-distance fiber optic cable, in order to improve the utilization rate of the fiber optic cable, and reduce the cost, transceiver and wavelength division multiplexer (WDM multiplexer) with the use of two-way information on the same fiber transmission.

Optical Transceiver modules can be classified according to the following aspects.

1. Optical Fiber Type

Single-mode fiber transceiver and Multimode fiber transceiver. The single-mode version has a transmission distance of 20 to 120 km, while the multimode one's is 2 to 5 km. Due to the different transmission distance, the transceivers' transmit power, receiver sensitivity and the use of wavelength will be different.

2. Optical Fiber Count

Simplex fiber transceiver and Duplex fiber transceiver. The simplex version receives the data sent in a single fiber transmission, While the duplex one receives data transmitted on a dual fiber transmission.By definition, single fiber devices can save half of the fiber, a fiber that is in the receive and transmit data, where the fiber is very applicable to resource constraints. These products use the wavelength division multiplexing techniques, mostly using the wavelength 1310nm and 1550nm.

3. Transmission Rate

Transmission rate refers to the number of gigabits transmitted per second, per unit of Mbps or Gbps. Optical modules cover the following main rate: low rates, Fast, Gigabit, 1.25G, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G and 40G.

4. Package

SFP, SFP+, GBIC, XFP, XENPAK, X2, 1X9, SFF, 200/3000pin, XPAK, etc.

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

• 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.

Knowledge You Should Know About HP ProCurve Mini-GBICs and SFPs

For the above products, there usually are many questions about them. The following infomation will make you to know more about them.

Supported Platform
According to HP ProCurve Networking Mini-GBIC Support Matrix, we can easily find out which Mini-GBICs and SFPs are supported on which ProCurve Systems. General rules are:

• Please use only genuine or high-quality 100% compatible ProCurve Mini-GBICs and SFPs on ProCurve System.


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

About the Version A, B, C

HP ProCurve Mini-GBICs and SFPs have three version, but you may not find A and B anymore in HP's official website. In fact, the version A, B and C are the development of HP ProCurve Mini-GBIC and SFP. Though there is no big difference between these three version, some improvement will be added in the newest version, and the supported platforms adjustment. The "revision C" Mini-GBICs (eg. J4858C, J4859C, J4860C) are supported in all ProCurve products that support Mini-GBICs. In addition, "revision B" and "revision C" mini-GBICs can be used together in any ProCurve switch that supports mini-GBICs. Actually, as the transitional products, HP stops offering the version A and version B. But version C are not supported on some old switches, thus, some users have still used the version A or version B. Fiberstore can support the 100% compatible HP ProCurve Mini-GBICs and SFPs at version A, B and C, such as J4858A/B/C, J4859A/B/C, J4860A/B/C.

Mini-GBICs and SFPs hot-swappable

All ProCurve 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 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.
