Description

Farsince 25G ER SFP28 is a hot‑pluggable optical transceiver designed for long‑distance 25‑Gigabit Ethernet over two strands of G.652 single‑mode fiber. Using a 1310 nm EML transmitter and an APD receiver in a standard SFP28 MSA housing with duplex LC/UPC interface, it supports link spans up to 40 km with digital diagnostics for in‑service monitoring. Typical deployments include metro access rings, campus or enterprise aggregation uplinks, mobile fronthaul/backhaul (CPRI/eCPRI), and long leaf‑spine interconnects where fiber runs exceed 10 km.

The module balances reach and power budget with stable operation across 0–70°C and DOM per SFF‑8472 for real‑time reporting of optical power, voltage and temperature. Built for broad interoperability, it follows SFP28 electrical specifications and common 25G Ethernet optics practice, enabling straightforward integration with switch, router and transport platforms. Farsince provides vendor‑specific coding, project labeling, acceptance testing, and matched LC patch cords to simplify rollout and ensure supply continuity.
