Description
Pb
OptixCom’s single mode fiber optics transceiver is
designed with high performance 1310 nm FP laser and
GBC-1250LX-ATXXK
(XX = 10, 40, 50)
Lead-Free
compliant with Gigabit Interface Converter (GBIC)
specifications. This product can be used at 1.0625
Gb/s for Fiber Channel or 1.25 Gb/s for Gigabit
Ethernet applications with 10 - 50 km transmission
distance with single mode fibers. .
The transceiver uses duplex SC connector for the
optical interface and SCA-2 host connector for the
electrical interface. The product is hot pluggable in
the z-axis along the transceiver module. The products
are RoHS compliant.
