Description
Reviews (0)

The Cisco GLC-LH-SMD SFP adheres to the industry-standard small form-factor pluggable (SFP) design, enabling seamless integration with Cisco switches and routers. It supports 1000BASE-LX/LH Ethernet over both single-mode and multimode fiber, facilitating flexible and scalable network routing on a port-by-port basis.

Operating with a 1310 nm wavelength, this SFP offers data transmission distances up to 10 km over single-mode fiber and approximately 550 m over multimode fiber (with the proper mode-conditioning patch cord). Built-in Digital Optical Monitoring (DOM) provides real-time insights into key performance metrics such as optical power, temperature, and voltage. The SFP is hot-swappable, enhancing uptime by allowing replacement without powering down network devices.

Physically, it features a robust metal housing with dual LC/PC fiber connectors and operates on a standard +3.3 V power supply. The design complies with IEEE 802.3z standards and includes eye safety certification. It’s engineered for reliability, ease of installation, and consistent interoperability across a wide range of Cisco and third-party platforms.
