Description

This Farsince SFP28 SR optical transceiver provides 25‑Gigabit Ethernet connectivity over multimode fiber in a compact, hot‑pluggable SFP28 form factor. It integrates an 850 nm VCSEL transmitter and PIN‑TIA receiver in a standard MSA housing with a duplex LC/UPC interface and digital diagnostics. Designed for short‑distance links, it supports up to 100 m on OM4 or 70 m on OM3, ideal for top‑of‑rack to aggregation, server NIC uplinks, storage networks, and switch‑to‑switch connections inside data halls and enterprise wiring rooms.

Engineered for predictable deployment, the module offers DOM per SFF‑8472 for real‑time monitoring of temperature and optical power to simplify operations and troubleshooting. Compliance with IEEE 802.3by 25GBASE‑SR and SFF‑8431/8432 ensures broad interoperability with SFP28 ports on switches, routers and adapters, and supports hot‑swap installation with standard OM3/OM4 cabling. Farsince can provide platform‑specific coding, project labeling and acceptance testing, and matched LC patch cords to streamline rollout and maintenance across large sites.
