Description

Springtek SFP transceivers are high performance, cost effective modules supporting data rate of 2.5Gbps and 20km 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 and SFF-8472 digital diagnostics functions.

Features

  • Supports up to 2.5Gbps bit rates
  • Hot-pluggable SFP footprint
  • 1310nm DFB laser and PIN photo detector, Up to 20km for SMF transmission
  • Compliant with SFP MSA and SFF-8472 with single LC receptacle
  • Single +3.3V power supply
  • Real Time Digital Diagnostic Monitoring
  • Operating case temperature:0 to +70°C,-40 to +85°C
  • RoHS compliant (lead free)

Applications

  • SDH STM-16 and SONET OC-48 system
  • 2x Fiber Channel
  • Router/Server interface
  • Other Optical links
