GBIC and SFP Information Specifications

When configuring bill of materials, some times ago, in Cisco’s Nextgen configuration tool available in commerce workspace, I found a new fiber modules in the option list. Tried to investigate what are those and that leads to the below findings.

Surprisingly found that Cisco announced end of sale for GLC-T. While GLC-XX-XMD= is the replacement product for GLC-XX-XM.

PrimusIT offers cost-effective standards-based compatible Cisco Transceivers. Just compatible Cisco SFP transceivers include: multimode optical modules GLC-SX-MM; Single-mode optical module GLC-LH-SM, GLC-ZX-SM; SFP copper module GLC-T; DWDM/CWDM SFP; 2.125G SFP transceiver module; 4G SFP module; BIDI SFP optical transceiver; SFP with DDM transceiver such as GLC-LH-SMD and so on.

The 1000BASE-LX/LH (long wavelength/long haul) GBIC module interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2miles(10 km) over single-mode fiber (SMF) versus the 3.1 miles (5km) specified in the standard.
