Product information

Description

Lightwin Optics LWO-SFP28-SR-BT is a 25 Gbit SFP28 transceiver designed for short-reach multimode fiber links. It supports LC-Duplex connections and delivers up to 25 Gbit/s over multimode cabling, reaching up to 70 m on OM3 and up to 100 m on OM4. The module is housed in a metal enclosure for improved electromagnetic immunity and is compatible with hot-pluggable SFP28 ports commonly used in data center switches and server NICs.

Advantages

The transceiver uses a VCSEL laser and PIN receiver to provide reliable 25 Gbit link performance with low power consumption (power dissipation < 1.2 W). It features an integrated dual CDR, single 3.3 V power supply, and a 2-wire interface offering Digital Diagnostic Monitoring for real-time optical and electrical parameter reporting. The metal case reduces EMI and the module follows the SFP28 mechanical footprint for broad interoperability.

Suitable for

  • Data center server-to-switch uplinks and leaf-spine fabrics
  • High-density switch ports requiring 25 Gbit short-reach multimode connections
  • Top-of-rack connections within the same equipment room using OM3/OM4 multimode fiber

When it may not be suitable

This SFP28 SR module is intended for short-reach multimode fiber and is not suitable for long-reach single-mode links or metro/long-haul applications. It also requires switches or NICs with SFP28 ports; it will not function in devices that lack the appropriate port or do not support 25 Gbit SFP28 optics.

Key specifications

  • Data rate: up to 25 Gbit/s
  • Maximum reach: 70 m on OM3, 100 m on OM4 multimode fiber
  • Connector: LC-Duplex
  • Optical components: VCSEL transmitter and PIN receiver
  • Power supply: single 3.3 V
  • Power dissipation: < 1.2 W
  • Form factor: SFP28 (hot-pluggable)
  • Enclosure: metal (reduced EMI)
  • Features: integrated dual CDR, 2-wire interface with Digital Diagnostic Monitoring

How to use

Insert the Lightwin SFP28 SR module into a compatible SFP28 port on a switch or server NIC while the host device is powered on or off (hot-pluggable). Connect LC-Duplex multimode fiber patch cords to the module's LC connectors, ensuring correct transmit/receive orientation. Verify link status via the host device and monitor diagnostics through the 2-wire DDM interface if supported by the equipment.

What to consider before purchase

  • Ensure your switch or NIC supports SFP28 25 Gbit optics and accepts third‑party transceivers
  • Confirm fiber type and distance: OM3 for up to 70 m, OM4 for up to 100 m
  • Use LC-Duplex multimode patch cords with correct polarity
  • Check power and thermal conditions in high-density environments to keep module power dissipation < 1.2 W within acceptable limits

Usage recommendations

For reliable 25 Gbit short-reach performance, use certified OM3/OM4 multimode fiber, maintain clean LC connectors, and monitor link parameters through the transceiver’s Digital Diagnostic interface when available.
