Compatible 1G SFP Transceiver – 1000BASE-LX/LH 1310nm, LC, 10 km (GLC-LH-SMD Compatible) sfp module

Product Description

This hot-swappable 1G SFP module is engineered for long-reach fiber links, supporting the 1000BASE-LX/LH standard. It operates at a 1310nm wavelength for deployments of up to 10 km on single-mode fiber (short multimode links are supported with a mode-conditioning patch cable). Factory-programmed for broad Cisco compatibility (GLC-LH-SMD profile), it features Digital Optical Monitoring (DOM) for real-time diagnostics of key optical parameters. It serves as a cost-effective, plug-and-play replacement for Cisco OEM modules, ideal for data center uplinks, enterprise backbones, and ISP access networks.

Product Features

• High-Speed Transmission: 1 Gbps (1000BASE-LX/LH) SFP module for Gigabit Ethernet requirements.
• Wavelength & Distance: 1310nm transmitter; up to 10 km on single-mode fiber (SMF); ~550 m on multimode fiber (MMF) with a mode-conditioning patch cable.
• Interface Type: Duplex LC connector for standard fiber patching.
• Intelligent Monitoring: Supports DOM/DDM for real-time reporting of Tx/Rx power, temperature, and bias current.
• Plug-and-Play: Pre-programmed for Cisco SFP ports (compatible with GLC-LH-SMD); hot-swappable for easy field replacement.
• Low Power Consumption: Typical low power draw for the SFP class.

Technical Specifications (Concise)

Note:​ Vendors may publish slightly different numbers (e.g., optical budget, exact temp ranges). For a precise datasheet, refer to the FS QA sheet or OEM documentation.

Typical Usage Scenarios

• Inter-Building Connectivity: Extend Gigabit Ethernet between buildings or floors using single-mode fiber runs up to 10 km.
• Cisco Equipment Upgrade: A cost-effective replacement for upgrading SFP ports in Cisco switches and routers.
• Network Backbone: Ideal for ISP access links, data center uplinks, and enterprise fiber backbones requiring 1 Gbps fiber.
• Legacy MMF Links: Utilize existing campus multimode fiber runs when paired with a mode-conditioning patch cable.
