Cisco GLC-SX-MMD SFP Module is 1000BASE-SX SFP transceiver module, MMF, 850nm, DOM -option This part is also known as CSC-GLCSXMMD.
Cisco GLC-SX-MMD SFP Module Product Overview
this SFP s designed for use with Cisco networking equipment and is functionally equivalent to Cisco part number GLC-SX-MMD=. This transceiver is manufactured to meet or exceed the specifications of the original Cisco unit and to comply with the Multi-Source Agreement (MSA) standards. Tripp Lite guarantees 100% compatibility with Cisco networking hardware and will initialize and perform identically to an OEM transceiver.
The information about the optical modules contained in the labels of the Cisco optical modules can help us distinguish optical modules. For example, SX and SR in optical module models represent short distances. Transmission, ZX, EXZ stands for long-distance transmission, etc. However, due to the variety and type of Cisco optical modules, we still easily confuse different types of optical modules. In this article, we will focus on the differences between Cisco GLC-LH-SMD, GLC-SX-MMD, and GLC-ZX-SM optical modules. Divided into several types of optical modules.

See the package type, speed, interface, and commercial temperature of the three optical modules are the same, but the other aspects are different. For example, we can see from the model. In addition to the “D” in the model of the GLC-ZX-SM optical module, the other two optical modules are available, and the “D” at the end of the model represents DOM work.From GLC-LH-SMD, GLC-SX-MMD, and GLC-ZX-SM optical modules. We can
Yes, this means that the GLC-ZX-SM optical module does not support DOM functionality, while the other two optical modules support it.
