SFP-4.25G-30KM,4.25Gbps SFP 10km Optical Transceiver

SFP-4.25G-30KM,4.25Gbps SFP 10km Optical Transceiver

Features

  • Single 3.3 V supply
  • Supports 1.0625/2.125/4.25Gb/s Fibre Channel Operation
  • Gigabit Ethernet compatible
  • 1310nm DFB Laser
  • SFP MSA SFF-8074i compliant
  • Digital Diagnostic SFF-8472 compliant
  • Compatible with RoHS
  • Operating case temperature:

Standard : 0 to +70°C
Industrial : -40 to +85°C

Applications

  •  Tri Rate 1.0625 / 2.125 / 4.25Gbp/s Fibre Channel
  •  1.25Gbp/s 1000Base-LX Ethernet and 1000Base-LX10 (Rate selectable version)


Description
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 the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA)1. They are compatible with Fibre Channel per FC-PI-2 Rev. 10.0. also simultaneously compatible with Gigabit Ethernet as specified in IEEE Std 802.3.
