1000Base 2 Channels BIDI CSFP Transceiver Module TX1490nm/RX1310nm 20km LC DOM
Description
The CSFP BIDI LX20 transceiver is with two independent data communication channels, for each separate channel this transceiver unit uses a highly reliable 1490nm DFB Laser transmitter and a 1310nm PIN Photodiode receiver, which will enable network system vendors to increase port density and data throughput, while reducing network equipment cost.
This CSFP BIDI LX20 module supports 1.063-1.25Gbps data rate and such applications as Gigabit Ethernet (1.25Gbps) and 1G Fiber Channel (1.0625Gbps), a max link up to 20km, operates in Standard 0°-70°C temperature range and has Double LC interface.
It is with the SFP 20-pin connector to allow hot plug capability. DDM/DOM optical diagnostic monitoring functions are available through an I2C interface, with provide diagnostic information about the present operating conditions.
This CSFP BIDI LX20 Transceiver is fully compliant to compact Small Form-Factor Pluggable (CSFP) MSA option 2 and CE/RoHS certified.
