## Summary description

25 Gbit SFP28 fiber optic transceiver from Lightwin Optics (model LWO-SFP28-SR-BT) for short-reach multimode links. Supports up to 70 m on OM3 and 100 m on OM4 using LC-Duplex connectors, with an SFP28 interface and 25 Gbit/s maximum throughput. RoHS compliant and backed by a 3-year warranty. Ideal for data center uplinks, switches and server connections.

## Long 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.
