SFP28-25G-SR Optical Transceiver 25G SFP28 SR 850nm 100M Module 25g sfp


The Nufiber SFP-25G-SR is a single-channel, pluggable, fiber-optic SFP28 transceiver module for 25G Ethernet applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125Gb/s up to 70m using OM3 fiber or 100m using OM4 fiber. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector. The optical interface uses duplex LC receptacle. This module incorporates Gigalight Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.


  • Hot-pluggable SFP28 form factor
  • Supports 25Gb/s data rate
  • Maximum link length of 70m on OM3 MMF and 100m on OM4 MMF
  • 850nm VCSEL laser and PIN photo-detector
  • Internal CDR on both Transmitter and Receiver channel
  • Duplex LC receptacle
  • Single 3.3V power supply
  • Power dissipation < 1W
  • Digital diagnostics functions are available via the I2C interface
  • RoHS-6 compliant
  • Commercial case temperature range: 0°C to 70°C
