It supports single‑mode fibre links up to 40 km using an LC BiDi interface (TX 1310 nm \/ RX 1550 nm). The complementary opposite‑wavelength module (TX1550\/RX1310) is required at the remote end to form a working link.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSupports 1000BASE‑LH at 1.25 Gbps (IEEE 802.3z).\u003c\/li\u003e\n  \u003cli\u003eBiDi single‑fibre operation: TX 1310 nm \/ RX 1550 nm — pair with complementary module on other end.\u003c\/li\u003e\n  \u003cli\u003eMaximum reach: up to 40 km over single‑mode fibre (SMF).\u003c\/li\u003e\n  \u003cli\u003eSFP form factor (mini‑GBIC), hot‑pluggable and MSA compliant.\u003c\/li\u003e\n  \u003cli\u003eDigital diagnostics monitoring (DDM\/DOM) for optical power and temperature reporting.\u003c\/li\u003e\n  \u003cli\u003eLow power consumption (≤ 1.5 W typical) and commercial operating range.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUse cases \u0026amp; compatibility\u003c\/strong\u003e\u003cbr\u003eIdeal for point‑to‑point Gigabit links where single‑fibre BiDi connectivity reduces fibre count.
