GLC-BX40-U-I-RF

1000BASE-BX40 SFP, 1310NM REMANUFACTURED

GLC-BX40-U-I-RF is a professionally remanufactured Cisco GLC-BX40-U-I SFP transceiver module, designed for single-strand single-mode fiber Gigabit Ethernet connectivity in enterprise and service provider network deployments. This bidirectional (BiDi) transceiver supports transmission distances of up to 40 kilometers, making it well-suited for long-haul campus and metropolitan area network links.

This remanufactured SFP transceiver meets Cisco performance specifications and has been thoroughly inspected and tested to ensure reliable optical operation. Validation includes verification of transmit power output and receive sensitivity, confirmation of proper wavelength separation for upstream and downstream channels, and functional testing for Gigabit Ethernet link establishment and stability.

Key Features:
• Single-strand single-mode fiber operation using WDM BiDi technology — TX at 1310 nm, RX at 1490 nm
• Gigabit Ethernet (1000BASE-BX40-U) data rate at 1.25 Gbps
• Reach of up to 40 km over G.652 single-mode fiber
• LC simplex connector interface for single-fiber cabling infrastructure
• Industrial temperature rating (-40°C to 85°C) for extended environment deployments
• Compatible with Cisco Catalyst, ASR, and ISR platforms supporting SFP slots
