Can We Interconnect SFP, SFP+, XFP, X2 and XENPAK?

FacebookTwitterGoogle+LinkedInRedditTumblrShare

There are many kinds of 10G optical transceivers in the market such as SFP+, XFP, X2 and XENPAK. So when we use these modules, the most confusing problem is if we can interconnect SFP+, XFP, X2 and XENPAK. Besides this, some module users also want to know if they can connect SFP to SFP+ or if then can connect 10GBASE-SR modules to 10GBASE-LR modules. In this article, I will display some common questions often asked by module users and give the right answer mainly based on Cisco optical transceivers.

1. Can we interconnect SFP-10G-SR to XENPAK-10GB-SR or X2-10GB-SR?
The answer is yes. For this problem, you just need the correct optic on each side. If your optics are singlemode you need singlemode patch cord. If your optics are multi-mode then you need multi-mode patch cord. SFP-10G-SR, XENPAK-10GB-SR and X2-10GB-SR are all multi-mode optics, so a multi-mode fiber can solve this problem.

2. Can LC-SC patch cord connect X2-10GB-SR between SFP-10G-SR?
Yes, it’ll work fine as long as your fiber patch cord is multi-mode. Actually, the SFP+ requires LC connector but the X2 may require a SC connector. So when connect SFP-10G-SR to X2-10GB-SR, we must use a LC-SC patch cable (LC connector on one fiber end, SC connector on the other fiber end).

3. Is it possible to connect X2-10GB-LR to SFP-10G-SR?
The answer is not possible. The Cisco X2-10GB-LR module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652). However, the Cisco SFP-10G-SR module supports a link length of 300m on OM3 multi-mode fiber (MMF,OM3) and 400m on OM4 multi-mode fiber (MMF,OM4). Actually, you need to use modules with the same wavelengths, i. e. SR to SR or LR to LR.

4. Can we connect SFP-10G-SR to GLC-SX-MM?
The SFP-10G-SR is 10 Gbps only. The GLC-SX-MM is 1 Gbps only. This question means can we force SFP-10G-SR to use 1Gbps speed?  This is a very common question and the response will always be the same. The answer is NO. Because the SFP-10G-SR is 10 Gbps only. It runs at 10 Gbps link rate and no other speed. GBIC, SFP, X2, QSFP, CFP modules will only negotiate to one speed and one speed only. You cannot interconnect them.

5. Can we connect GLC-SX-MM to GLC-LH-SM?
Some users wonder if they can use GLC-SX-MM together with GLC-LH-SM? In fact, the GLC-SX-MM is multi-mode LED-based. The GLC-LH-SM is singlemode laser-based. They may (sometimes) work with mode conditioning patch (MCP) cables but it’s not generally a good idea unless it’s completely unavoidable.

FS offers a variety of fiber optic transceivers (SFP+, XFP, X2 and XENPAK) at very economical prices which can satisfy your requirements from 1G to 100G Ethernet.

Cisco SFP Transceiver Modules for Opitcal Network

Cisco Systems, Inc. is an American multinational corporation headquartered in San Jose, California, that designs, manufactures, and sells networking equipment. With the rapid development of optical communication, Cisco’s products of optical networking are being used more and more widely all around the world. Among them, the SFP transceiver module is a critical component. In this article, Cisco SFP will be introduced.

Cisco Products Refer To Optical Communication

In fact, Cisco produces many optical networking equipment, such as optical services modules, optical transponders, optical transceiver modules and a comprehensive portfolio of WDM transmission modules, which includes optical terminal filters, optical amplifiers, optical service channel, and others, to support the network applications of enterprise and service provider customers.

Cisco SFP Transceiver Modules

Cisco SFP transceiver modules support Ethernet, Sonet/SDH and Fibre Channel applications across all Cisco switching and routing platforms. The Cisco portfolio of hot pluggable interfaces offers a rich set of choices in terms of speeds, protocols, reaches and supported transmission media. Generally, these SFP transceiver modules are divided into three types as following three sorts:
