Is it possible to interconnect SFP, SFP+, XFP, X2 and XENPAK Optical module.optic transceiver module manufacture

There are many 10G Optical module on the market, such as sfp+, XFP, X2 and xenpak. Can we interconnect sfp+, XFP, X2, and xenpak? Some module users want to know if they can connect SFP to SFP+or single mode to multimode modules. In this article, we will list some common user questions and provide the correct answers based on Cisco optical modules.

1. Is it possible to replace sfp-10g-sr, xenpak-10gb-sr, or x2-10gb-sr?

The answer is yes. If the module is single mode, a single mode jumper is required. If it is multimode, use multimode jumpers. Sfp-10g-sr, xenpak-10gb-sr, and x2-10gb-sr are multimode modules, so multimode fibers can be used to solve this problem.

2. Can the LC-SC jumper be connected to x2-10gb-sr and sfp-10g-sr?

Yes, as long as you use multimode LC-SC jumpers. The actual sfp+requires an LC connector, but x2 requires an SC connector. When connecting sfp-10g-sr to x2-10gb-sr, LC-SC multimode jumper must be used.

3. Can we connect x2-10gb lr to sfp-10g-sr?

The answer is that the X2-10gb-lr module supports a transmission distance of 10km on standard single mode (G.652) fiber. However, the sfp-10g-sr module supports a transmission distance of 300 meters on OM3 multimode fiber. You need to use modules with the same wavelength, such as SR to SR or LR to LR.

4. Can we connect sfp-10g-sr to glc sx mm?

Does this issue mean that we can use 1Gbps speed for SFP-10g-SR? This is a very common question, and the answer is no. Because the speed of sfp-10g-sr is 10Gbps. It operates at a link rate of 10Gbps and has no other speed. GBIC, SFP, X2, qsfp, and CFP modules operate at only one rate and cannot be interconnected.
