H3C SFP-GE-LX-SM1490-BIDI 1000BASE-BX-D BiDi SFP 1490nm-TX/1310nm-RX 10km DOM LC SMF Transceiver Module Full English Datasheet

Basic Parameter Table

Core Product Features

1. Original H3C gigabit single-fiber BiDi SFP module, must be used in pairs with SFP-GE-LX-SM1310-BIDI (BX-U), fully compatible with H3C S5130/S5560/S6520 series enterprise switches.
2. Complies with SFP MSA BiDi single-fiber bidirectional standard, only one simplex LC single-mode fiber is needed for simultaneous transmit and receive, cutting fiber cost by half, stable 10km transmission over G.652 SMF.
3. Built-in DOM digital optical monitoring circuit, real-time monitoring of transmit optical power, receive optical power, supply voltage, chip temperature and laser bias current for quick fault location.
4. Hot-swappable plug-and-play SFP design, no need to power off equipment during replacement, ideal for FTTH, community broadband and campus access networking.
5. Sealed metal housing with integrated heat dissipation structure, strong anti-electromagnetic interference performance, suitable for weak current cabinets and indoor computer room deployment.
6. Cost-effective fiber-saving BiDi solution, widely deployed in FTTH broadband access, small park cross-building gigabit interconnection and short-distance HD video monitoring links.

Typical Application Scenarios

1. FTTH, residential community and campus broadband aggregation within 10km single-mode fiber coverage (matched BX-U & BX-D pair set).
2. Short-distance cross-building fiber interconnection for offices and small factories, low-cost HD monitoring signal transmission.
3. Restrictions: Not applicable for multi-mode fiber, 40km+ long-distance links and 10G/25G high-speed Ethernet; must be matched with opposite wavelength BIDI-U module.
