25G SFP28 LR Optical Transceiver – 1310nm 20km LC SMF

SVNK 25G SFP28 LR Optical Transceiver (10 km, SMF)

The SVNK 25G SFP28 LR Optical Transceiver is a high-performance module engineered for 25 Gigabit Ethernet connectivity over single-mode fiber. Operating at a nominal wavelength of 1310 nm, it supports transmission distances of up to 10 km, making it ideal for enterprise backbones, telecom access networks, and data center interconnect applications.

Fully compliant with the SFP28 MSA, SFF-8472 Rev 12.2, SFF-8432, and applicable portions of SFF-8431 Rev 3.0, this transceiver ensures seamless interoperability with leading network equipment. It also supports CPRI and eCPRI standards, enabling deployment in mobile fronthaul and 5G transport environments.

The module integrates a high-performance 1310 nm DML (Directly Modulated Laser) transmitter and a high-sensitivity PIN photodiode receiver, combined with internal Clock and Data Recovery (CDR) on both transmit and receive channels to deliver excellent signal integrity, low jitter, and stable long-distance operation.

Housed in a compact, hot-pluggable SFP28 form factor with a 20-pin edge connector, the transceiver is optimized for low power consumption, thermal efficiency, and high port density switch platforms. Built-in Digital Optical Monitoring (DOM/DDM) provides real-time access to critical operating parameters.
