Networking

Cisco is a worldwide leader in the telecommunication industry whose routers, switches are very welcome among the users. To work well with those Cisco networking applications, Cisco SFP transceivers are the best choice. GLC-SX-MM, GLC-SX-MMD, GLC-SX-MM-RGD  and  SFP-GE-S are different types of Cisco 1000BASE SFP transceiver module. All these transceiver modules comply with IEEE 802.3z 1000BASE standard. And since there are similar specifications for these four transceiver modules, users may be confused when they need to choose one SFP module for their Cisco switches. Here we’ll make a comparison of GLC-SX-MM,  GLC-SX-MMD , GLC-SX-MM-RGD and SFP-GE-S transceiver modules to help you choose the suitable one. Which transceiver module will you choose?

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...
