The GBS-GLX10 is a high performance 1310nm multimode/singlemode GBIC transceiver supporting full duplex, gigabit speeds on multimode/singlemode fiber for distances of up to 50m/550m/10km on 62.5µ /50µ /9µ respectively. This hot pluggable unit has a metal housing to reduce EMI and to increase durability. The GBS-GLX10, 1000BaseLX interface fully complies with the IEEE 802.3z 1000BaseLX standard. However, the higher optical quality allows them to reach 10 km over single-mode fiber (SMF) versus the 5 km specified in the standard. 1310nm Multimode/Singlemode Transceiver Duplex SC Connector Metal Enclosure Reduces EMI 3.3V Power Supply Hot Pluggable Multi-Vendor Device Support Up to 550m on 50/125µ Up to 550m on 62.5/125µ Up to 10km on 9/125µ Up To 1.25Gbps Bi-Directional (Gigabit) Up To 1.0625Gbps Bi-Directional (Fiber Channel).
