Product Description

Cisco Compatible 1000BASE-SX 1310nm MMF 2km DOM Duplex LC SFP Optical Module





The GIGAOPTO's GTS-L1312-M2DC multi-mode transceiver is a small form factor pluggable module for bi-directional serial optical data communications such as Ethernet and SDH/SONET. This transceiver allows hot plug capability with the SFP 20-pin connector. It’s compatible with the IEEE 802.3z 1000BASE-SX standard and can operate on standard multimode fiber optic link spans of up to 2 km. The module has a built-in DOM (Digital Optical Monitoring) function to allow monitoring parameters of modules. This SFP module series is compliant with RoHS6 standard and SFP MSA specification.
