Description

Farsince 100G QSFP28 LR4 Industrial is a hot‑pluggable optical transceiver that delivers 100‑Gigabit Ethernet up to 10 km on G.652 single‑mode fiber. The module converts four 25G electrical lanes into four LAN‑WDM optical channels around 1295–1310 nm and multiplexes them onto a duplex LC interface. It fits QSFP28 ports on switches, routers and transport platforms, and is used for carrier access uplinks, outdoor cabinet aggregation, industrial plant backbones and data‑center to campus connections where long reach and LC patching are required.

An EML/PIN optical engine maintains link stability across a -40 to +85°C case range, with digital diagnostics (DOM) available for real‑time monitoring. Interoperability with IEEE 802.3ba 100GBASE‑LR4 and QSFP28 MSA ensures seamless integration; FEC is supported when enabled by the host. The compact form factor supports high‑density panels and hot‑swap installation. Farsince provides platform coding for major OEM equipment, project labeling, acceptance testing and stable volume supply for deployment and spares management.
