Alcatel-Lucent SFP-GIG-BX-D20 Compatible 1000BASE-BX20-D BiDi SFP Module 20km(SMF, 1490nm-TX/1310nm-RX, Simplex LC, DOM)

Product Overview

The HYTOPTODEVICE Alcatel-Lucent SFP-GIG-BX-D20 compatible BiDi SFP transceiver is a professional single-fiber bidirectional gigabit optical module, specially designed for overseas enterprise network renovation, MSP project deployment, and large-scale European and American IT procurement. Featuring accurate Tx1490nm/Rx1310nm wavelength configuration and 20km single-mode fiber transmission capacity, this simplex LC SFP module serves as the perfect downlink pairing solution for 1000BASE-BX-U uplink modules, helping global buyers save half of fiber cabling costs in network construction.
Different from generic ordinary optical modules, this SFP-GIG-BX-D20 equivalent transceiver supports flexible OEM white-label customization, private logo printing, and customized packaging services, fully meeting the personalized branding needs of overseas distributors and system integrators. All products pass strict real-Cisco-device testing and 72-hour high-temperature aging screening, ensuring zero-error plug-and-play operation on mainstream Alcatel-Lucent devices without firmware conflicts or alarm logs. Compliant with SFF-8472 and IEEE 802.3z international standards, it retains complete DDM real-time monitoring functions to support long-term stable operation of commercial network projects.

Key Technical Specifications

Follow standardized operation rules to extend service life and maintain steady link performance of your BiDi SFP Transceiver:

1. Complementary Pairing Requirement Bidirectional transceivers must be deployed in matched wavelength pairs. This TX1490/RX1310 BiDi SFP Module requires a counterparty TX1310/RX1490 transceiver at the opposite fiber end; mismatched wavelength pairs cannot establish valid fiber links.
2. Fiber Type Restriction Only use standard 9/125μm single mode fiber (SMF) with LC/UPC patch cords. This transceiver cannot operate normally on multi-mode fiber (MMF), which triggers severe attenuation and persistent random bit errors.
3. Distance & Attenuation Control Optimized for stable 20km single-fiber links. For lab testing or field deployment under 5km, an external optical attenuator is mandatory to prevent receiver overpowering, signal saturation and permanent internal optical chip damage.
4. Optical Port Dust Protection LC optical ports and fiber end faces are highly sensitive to dust and fingerprint contamination. Always reinstall protective dust caps on idle module ports and unused fiber connectors after disconnection.
5. Hot-Plugging Operation Guidance This MSA-compliant BiDi SFP Transceiver supports safe hot swap. Leave several seconds between removal and reinsertion to let Cisco IOS complete full hardware recognition and avoid unexpected link flapping.
