Description

Overview:

The 1.25GB 1550nm GBIC transceiver is a SFP transceiver used with Single-mode fiber to reach up to 49.7 Miles(80Km). The Transmitter section uses a DFB transmitter to transmit optic signals. These Gigabit Interface Converter transceivers (GBIC) are easy to use transceivers that are compact and swappable complying with the SFF 8472 standards.

Key Features:

  • Compliant with SFF-8472
  • Up to 1.25Gb/s data links
  • DFB laser transmitter and PIN photo-detector
  • Up to 49.7 Miles(80Km) on 9/125µm SMF
  • GBIC footprint
  • Duplex SC/UPC type pluggable optical interface
  • Low power dissipation
  • Metal enclosure, for lower EMI
  • RoHS compliant and lead-free
  • Single +5V power supply
  • Case operation Temperature range from 32°F to +158°F(0°C to +70°C)
