CFP module transceivers. How to replace them?

CFP is a hot-pluggable form-factor module used in fiber optic networks. CFP is an acronym from 100G (C = 100 in Roman numerals; Centum) Form-factor Pluggable. This optical transceiver is designed for 100G interfaces. 

Since 2009 the CFP has evolved into the CFP2 and CFP4 standards, which are 1/2 and 1/4 respectively the size of the original specification. CFPs are currently manufactured in these categories:

10 x 10Gb/s (CFP, CFP2 & CFP4), 4 x 25Gb/s (CFP, CFP2 & CFP4), 8 x 25Gb/s (CFP2) & 8 x 50Gb/s (CFP2).

In 2015 a new CFP8 specification was proposed, supporting data rates of 16 x 25Gb/s, 8 x 50Gb/s & 4 x 100Gb/s.

The C form-factor pluggable is both hot-insertable and hot removable. When removing a transceiver, the line card keeps functioning, but the removed module is not able to transmit or receive data any longer.

How to remove a CFP module quang?

Put an antistatic mat on a flat surface to receive the transceiver. Make sure you have a rubber safety cap somewhere handy for the CFP and the cable.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
Label the cable connected to the CFP transceiver so that you can later reconnect it to the correct CFP transceiver.
Disconnect the cable from the CFP transceiver and cover the transceiver and the end of the cable with a rubber safety cap.
Arrange and secure the cable.
Unseat the CFP transceiver from the line card. Pull the transceiver out of the line card and place it on the antistatic mat.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
Make sure that a rubber safety cap covers the transceiver.
Place CFP over the port in the line card in a way that the connector end enters the slot first. Slide the CFP into the slot.
Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver.
Arrange and secure the cable.
Make sure that the CFP is functioning correctly.
PeakOptical offers a broad selection of C form-factor pluggable together with other fiber optic products such as multimode and single-mode cables, accessories, and a complete matrix of the latest transceivers. For more information about the items we can provide, please check our Netsystem.

Which one should you choose?

It depends on the switch or line card you are using. Usually, they come with empty slots that fit either GBIC or SFP and you will need to adapt to that.

Also, when it comes to choosing if GBIC or SFP suits you more, the required number of interfaces and the availability of switches and line cards influence your decision a lot. Let’s take this example: if you want to fiber interfaces on a line card of 6500 switch, you will not use a 48 port SFP line card, instead, you will use a 2 port GBIC line card. But, if you need a 24 fiber interfaces, you will definitely not use a 16 port GBIC line card, but rather a 48 port SDP line card.
