Description
The 3Com SFP-GE-LH40-SM1550 is a high-performance Small Form-Factor Pluggable (SFP) transceiver module engineered for extending Gigabit Ethernet networks over significant distances. This module specifically adheres to the 1000Base-LH standard, which dictates operation over single-mode fiber optic cable at a wavelength of 1550nm. Its primary application is in scenarios requiring reliable, high-speed data transmission across metropolitan or campus area networks where distances can exceed the capabilities of shorter-range transceivers. The module supports a maximum transmission distance of up to 40 kilometers (approximately 24.8 miles), making it an ideal choice for connecting geographically dispersed network segments, data centers, or critical infrastructure. The use of single-mode fiber allows for lower signal attenuation over long hauls, ensuring data integrity. The standard LC duplex connector ensures a secure and robust physical connection to the fiber optic cabling infrastructure. Designed for hot-swappable insertion into compatible SFP ports on switches, routers, and network interface cards, the 3Com SFP-GE-LH40-SM1550 offers flexibility and ease of deployment without requiring network downtime. It complies with industry standards, ensuring interoperability with a wide range of networking equipment. The module provides a cost-effective solution for upgrading network infrastructure to support higher bandwidth demands over extended reach.
