Description

This 1000BASE‑SX SFP optical transceiver enables 1.25‑Gigabit Ethernet over multimode fiber using a duplex LC interface. It integrates an 850 nm VCSEL transmitter and PIN receiver in an SFP MSA housing with digital diagnostics (DOM). Designed for short‑reach campus and data‑center connections, the module supports links up to 550 m on 50/125 μm OM2‑grade fiber and is widely used between access switches, aggregation layers, and storage or server NICs where reliable, low‑power optics are preferred over copper.

Engineered for straightforward deployment, the unit is hot‑swappable, supports real‑time monitoring via I2C DOM, and follows IEEE 802.3z and SFF standards for broad host compatibility. Consistent optical parameters and stable temperature performance simplify provisioning across large fleets. Farsince can supply coding for major switch platforms, project‑specific labeling and testing, and matched patch cords to streamline installation and ongoing maintenance.
