1G SFP EX Optical Transceiver – 1310nm 40km LC SMF | 1000Base-EX

SVNK 1GBASE-SX SFP Optical Transceiver (MMF, 850 nm)

The SVNK 1GBASE-SX SFP Optical Transceiver is a high-performance, small form-factor pluggable module designed for bidirectional serial optical data communications in Gigabit Ethernet (1000BASE-SX) and Fibre Channel (FC-PH2) applications. It supports reliable short-reach optical transmission over multimode fiber, making it ideal for enterprise networks, data centers, and high-density switching environments.

The module operates at a nominal wavelength of 850 nm and utilizes an advanced VCSEL laser transmitter with a high-sensitivity photodiode receiver to deliver stable performance and low bit-error rates. It supports data rates up to 1.25 Gb/s and provides transmission distances of up to 550 meters over 50/125 µm multimode fiber and 300 meters over 62.5/125 µm multimode fiber.

Housed in a compact hot-pluggable SFP form factor with a standard 20-pin edge connector, the transceiver enables flexible deployment, easy upgrades, and seamless integration into a wide range of networking platforms.
