155M-BiDi-SFP-GOXS-BI5403-120D

155M-BiDi-SFP-GOXS-BI5403-120D

155Mbps SFP Bi-Directional Transceiver, 120km Reach 1550nm TX / 1490 nm RX

  •  Dual data-rate of 155Mbps/125Mbps operation
  • 1550nm DFB laser and PIN photo detector for 120km transmission
  • Compliant with SFP MSA and SFF-8472 with single LC receptacle
  • Digital Diagnostic Monitoring: Internal Calibration or External Calibration
  • Compatible with RoHS
  • +3.3V single power supply
  • Operating case temperature: Standard : 0 to +70°C Industrial : -40 to +85°C

The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of 125Mbps/155Mbps and 120km transmission distance with SMF.

The transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472.

Applications

  • SDH STM-1, S-1.1,L-1.1, L-1.2
  • SONET OC-3 IR1,LR1,LR2
  • Router/Server interface
  • Other optical transmission systems
