How to Install or Remove QSFP Transceiver Module

QSFP/QSFP+ Installing Steps

Step 1: Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack.

Step 2: Remove the QSFP+ transceiver module from its protective packaging.

Step 3: Check the label on the QSFP+ transceiver module body to verify that you have the correct model for your network.

Step 4: For optical QSFP+ transceivers, remove the optical bore dust plug and set it aside.

Step 5: For transceivers equipped with a bail-clasp latch:
a. Keep the bail-clasp aligned in a vertical position.
b. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Step 6: For QSFP+ transceivers equipped with a pull-tab:
a. Hold the transceiver so that the identifier label is on the top.
b. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Step 7: Press firmly on the front of the QSFP+ transceiver with your thumb to fully seat the transceiver in the module's transceiver socket.
Please Note: If the latch is not fully engaged, you might accidentally disconnect the QSFP+ transceiver module.

Step 8: For optical QSFP+ modules, reinstall the dust plug into the QSFP+ transceivers optical bore until you are ready to attach the network interface cable. Please Note: Do not remove the dust plug until you are ready to attach the network interface cable.

QSFP/QSFP+ Removing Steps

Step 1: For optical QSFP+ transceivers, disconnect the network interface cable from the QSFP+ transceiver connector.

Step 2: For QSFP+ transceivers equipped with a bail-clasp latch.
a. Pivot the bail-clasp down to the horizontal position.
b. Immediately install the dust plug into the transceivers optical bore.
c. Grasp the sides of the QSFP+ transceiver and slide it out of the module socket.

Step 3: For QSFP+ transceivers equipped with a pull tab latch
a. Immediately install the dust plug into the transceiver's optical bore.
b. Grasp the tab and gently pull to release the transceiver from the socket.
c. Slide the transceiver out of the socket.

Step 4: Place the QSFP+ transceiver into an antistatic bag.

Note: In fact, the installing or removing steps of the mentioned transceiver modules are the general case. Different transceiver modules of different brands have their own features. We should ask the vendor to get more informations when you face a problem that we do not mentioned here. In addition, to save more money, we suggest that compatible 3rd transceiver modules may be another good choice but you should ensure that your vendor is reliable.

Fiberstore's fiber optic transceivers are 100% compatible with major brands like Cisco, HP, Juniper, Nortel, Force10, D-link, 3Com.

Introduction of Cisco QSFP Cables

What is QSFP?

The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver used for data communications applications. It interfaces networking hardware to a fiber optic cable. It is an industry format jointly developed and supported by many network component vendors, allowing data rates from 4x10 Gbit/s. The format specification is evolving to enable higher data rates; as of May 2013, highest possible rate is 4x28 Gbit/s.

What is QSFP+ Cable?

QSFP+ Cable Assemblies are high speed, low latency, twinaxial copper cables used for high speed network backbones, enterprise network switching and network storage. The cables offer a highly cost-effective way to establish a 40 Gigabit link between QSFP+ ports of QSFP+ switches within racks and across adjacent racks. QSFP+ cables are used for 40GBASE and Infniband standards, to maximize performance.We provide QSFP+ cables including 40G QSFP+ passive copper cables, active copper cables and active optical cables. In addition, Optical QSFP cables also have high speed data rates and support Ethernet, Infiniband, Fibre Channel and other applications. One can buy them from various reputable online stores. These cables are reasonably priced and available in different lengths.

Cisco QSFP+ Cables

Cisco 40GBASE QSFP+ portfolio offers customers a wide variety of high-density and low-power 40-Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider applications.

Various types of Cisco QSFP+ cables are:

Cisco QSFP to Four SFP+ Copper Breakout Cables

Cisco QSFP to four SFP+ copper direct-attach breakout cables (Figure 1) are suitable for very short distances and offer a very cost-effective way to connect within racks and across adjacent racks. These breakout cables connect to a 40G QSFP port of a Cisco switch on one end and to four 10G SFP+ ports of a Cisco switch on the other end. Cisco currently offers passive cables in lengths of 1, 3, and 5 meters and active cables in lengths of 7 and 10 meters.

Cisco QSFP to Four SFP+ Active Optical Breakout Cables

Cisco QSFP to four SFP+ active optical breakout cables are suitable for very short distances and offer a flexible way to connect within racks and across adjacent racks. Active optical cables are much thinner and lighter than copper cables, which make cabling easier. Active optical cables enable efficient system airflow and have no electromagnetic interference (EMI) issues, which is critical in high-density racks. These breakout cables connect to a 40G QSFP port of a Cisco switch on one end and to four 10G SFP+ ports of a Cisco switch on the other end. Cisco currently offers active optical breakout cables in lengths of 1, 2, 3, 5, 7, and 10 meters.

Cisco QSFP to QSFP Active Optical Cables

Cisco QSFP to QSFP copper direct-attach 40GBASE-CR4 cables are suitable for very short distances and offer a flexible way to connect within racks and across adjacent racks. Active optical cables are much thinner and lighter than copper cables, which make cabling easier. Active optical cables enable efficient system airflow and have no EMI issues, which are critical in high-density racks. Cisco currently offers active optical cables in lengths of 1, 2, 3, 5, 7 and 10 meters.
