Unlike common SFP transceiver, BiDi SFP transceiver is only with one port which uses an integral WDM coupler to transmit and receive signals over a single strand fiber.
1.25G Bidi SFP Optical transceiver module with DDM/DOM
- Data Rate: 1.25Gb/s
- Wavelength:
– 20KM (TX1550nm/RX1310nm)
– 40KM (TX1550nm/RX1310nm)
– 80KM (TX1550nm/RX1490nm) - Distance: 20KM/40KM/80KM
- Source: DFB+PIN(20KM/40KM/80KM) DFB+APD photo-detector(120KM)
ATZ BiDi SFP optical transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.063Gbps up to 120km transmission distance.
The Bidi SFP transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor ,the 1550nm DFB laser transmitter + PIN photodiode + APD photo-detector integrated with a trans-impedance preamplifier (TIA) and MCU control unit. The module data links up to 120KM on 9/125um single mode fiber. All modules satisfy class I laser safety requirements.
The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
