25G SFP28 LWDM Optical Transceiver 30KM Single-Mode Fiber LC

The FiberMania 25G SFP28 LWDM optical transceiver is a high-performance, long-reach module engineered for bandwidth-efficient optical networks. Utilizing LWDM technology in the O-band spectrum, it allows multiple 25Gbps channels to share a single strand of single-mode fiber, improving fiber utilization and reducing infrastructure costs without compromising performance.

Designed for transmission distances up to 30 kilometers, this module is ideal for 5G fronthaul, metro access networks, and data center interconnect applications. Its advanced DFB laser with TEC control, coupled with a high-sensitivity APD receiver, ensures stable wavelength performance, strong signal integrity, and reliable operation even under challenging environmental conditions.

Housed in a hot-pluggable SFP28 form factor with a duplex LC interface, the transceiver integrates seamlessly with existing 25G network equipment. With low power consumption, a high-speed 25GAUI electrical interface, and real-time digital diagnostics, it offers a scalable, energy-efficient solution for dense optical deployments requiring multiple wavelength channels.
