SKU: STI-OPB1250-3540-5340SDTR Category:


Optcore’s OPB1250-3540DCR is a hot-pluggable SFP bi-directional (BiDi) transceiver module specifically for duplex optical data communications such as 1000BASE-BX Gigabit Ethernet per IEEE802.3z and 1G Fiber Channel extended reach application. This 1G BiDi SFP module provides 40km transmission distance over a single strand of single-mode fiber. Compared with commonly used dual fiber SFP transceiver modules, this BiDi SFP transceiver allows end users to reduce the total cost on fiber cabling infrastructure by requiring half of the fiber cables, providing increased transmission capacity very convenient without installing new fibers.

The transmitter section uses a 1310nm DFB laser that is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses a high-speed 1550nm InGaAs PIN photodiode (PD) integrated with a trans-impedance preamplifier (TIA). The BiDi SFP module is fully compliant with the SFP Multi-Sourcing Agreement (MSA) and SFF-8472. For further information, please see SFP MSA and SFF-8472 standard.
