Description
Cisco GLC-LH-SMD – 1000BASE-LX/LH Gigabit SFP Transceiver Module
The Cisco GLC-LH-SMD is a 1 Gbps Gigabit Ethernet SFP transceiver module designed for use with both multimode fiber (MMF) and single-mode fiber (SMF). It supports long-distance data transmission, making it ideal for enterprise networks, data centers, and service providers that require high-speed fiber connectivity.
Key Specifications:
- Form Factor: SFP (Small Form-Factor Pluggable)
- Interface: LC Duplex Connector
- Data Rate: 1.25 Gbps (Gigabit Ethernet & Fiber Channel)
- Wavelength: 1310 nm (for both MMF & SMF)
- Transmission Distance:
- Single-Mode Fiber (SMF): Up to 10 km (6.2 miles)
- Multimode Fiber (MMF): Up to 550m (1,804 feet) using OM2 fiber
- Power Consumption: 1W (low power usage)
- DOM Support: Yes (Digital Optical Monitoring for diagnostics and performance monitoring)
- Operating Temperature: 0°C to 70°C (Standard version)
- Hot-Swappable: Yes, can be installed or removed without rebooting the switch or router
