1G SFP SX Optical Transceiver – 850nm 550m LC MMF | 1000Base-SX Module

SVNK 1G SFP SR Optical Transceiver (MMF, 850 nm)

The SVNK 1G SFP SR Optical Transceiver is a high-performance, short-reach optical module designed for Gigabit Ethernet and CPRI applications. It supports data rates of up to 1.1 Gb/s and transmission distances of up to 500 meters over OM4 multimode fiber and 300 meters over OM3 multimode fiber, using a duplex LC connector.

The module integrates an advanced 850 nm VCSEL laser transmitter and a high-sensitivity PIN photodiode receiver, delivering stable optical output, excellent signal integrity, and low bit-error rates. Precision optical alignment and optimized electrical design ensure consistent performance in dense data center and enterprise networking environments.

Digital Diagnostics Monitoring (DDM/DOM) is supported via a 2-wire serial interface in accordance with SFF-8472, enabling real-time monitoring of temperature, voltage, laser bias current, transmit power, and receive power.

Each SVNK transceiver is individually tested and verified for interoperability with leading platforms, including Cisco switches, routers, servers, and Network Interface Cards (NICs), ensuring seamless deployment and reliable operation.

Housed in a compact, hot-pluggable SFP form factor, the module is optimized for low power consumption, thermal stability, and flexible integration across a wide range of enterprise, cloud, and data center equipment.
