It uses a single fibre (simplex LC) to provide point‑to‑point links up to 20 km and is intended for data centre, campus and network interconnect use in switches, routers and servers. Supports hot‑plug and digital diagnostic monitoring (DDM\/DOM) for real‑time optical diagnostics.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSingle‑fibre BiDi — saves fibre by using one strand (paired with complementary module).\u003c\/li\u003e\n\u003cli\u003e1.25 Gbps (1000BASE‑LX) operation — compatible with Gigabit fibre ports.\u003c\/li\u003e\n\u003cli\u003eWavelengths: TX 1550 nm \/ RX 1310 nm (this SKU).\u003c\/li\u003e\n\u003cli\u003eReach: up to 20 km over single‑mode fibre (SMF).\u003c\/li\u003e\n\u003cli\u003eDigital Diagnostic Monitoring (DDM\/DOM) for optical parameter reporting.\u003c\/li\u003e\n\u003cli\u003eLow power consumption (≤ 1.5 W typical).
