25G LR SFP28 Optical Transceiver Module 1310nm 10KM DDM LC SMF

A 25G LR SFP28 optical transceiver module is a hot-pluggable optical module designed for 25Gbps Ethernet transmission over single mode fiber (SMF). This sfp28 module uses a 1310nm DFB laser, LC duplex connector, and supports transmission distance up to 10km, making it suitable for telecom access, metro networks, 5G bearer links, and data center interconnection.

The main advantage of a 25GBASE-LR SFP28 module is that it provides 25Gbps transmission over 10km single mode fiber, offering higher bandwidth than 10G modules while maintaining low power consumption and compact SFP28 form factor. This makes the sfp28 optical module suitable for networks that need higher capacity but still require efficient port density and stable long-reach optical performance.

An sfp28 transceiver module is used in high-speed optical networks to connect switches, routers, servers, and transport equipment over fiber. Typical applications include 5G fronthaul and backhaul, metro access, enterprise private optical links, and data center interconnection. For 25G network upgrades, the sfp28 module provides a practical solution for medium-distance SMF transmission.

The main difference between SFP, SFP+, and SFP28 modules is the supported data rate and typical application scenario.

Compared with SFP and SFP+, the SFP28 module provides higher bandwidth in a similar compact form factor, making it a practical choice for next-generation 25G optical networks.
