Description

The GLC-LH-SMD is another Cisco SFP (Small Form-factor Pluggable) transceiver module designed for long-range fiber-optic connections. It is built to work with single-mode fiber (SMF) and supports Gigabit Ethernet (1GbE) speeds. Here’s a breakdown of its key features:

Key Features:

• Form Factor: SFP (Small Form-factor Pluggable).

• Speed: Supports 1 Gigabit Ethernet (1GbE).

• Connector Type: LC Duplex connectors.

• Wavelength: Typically operates at 1310 nm, which is common for long-range fiber connections.

• Transmission Distance:

  • This module can transmit over single-mode fiber (SMF) at distances of up to 70 kilometers (43.5 miles), depending on the type of fiber used and the specific network conditions.

  • It’s ideal for long-distance interconnects between network devices such as switches, routers, and other fiber-optic enabled systems.

• Power: Powered by the host device through the SFP slot, no external power supply is required.

• Compliance: Meets IEEE 802.3z standards for Gigabit Ethernet.

• Temperature Range: Typically designed for standard temperature ranges (0°C to 70°C), but always double-check the specific datasheet for exact ranges.

• Optical Budget: Offers a higher optical budget, making it ideal for longer fiber links compared to standard short-range modules.

Applications:

• Long-Distance Fiber Links: The GLC-LH-SMD is specifically designed for long-distance transmission, supporting distances up to 70 km. It’s commonly used in large enterprise networks or service provider environments where long-distance fiber connections are needed.

• Data Centers & Campus Networks: This transceiver is useful in connecting data centers, campus networks, and interbuilding links, where high-speed connections over long distances are a requirement.

• Metro and Wide Area Networks (WANs): It’s also a solid choice for metro and wide-area network links where distance and reliability are important factors.

Compatibility:

• Compatible with Cisco switches and routers that feature SFP slots. It’s important to note that, like most SFPs, it’s most optimized when used with Cisco equipment, though it may work with other compatible devices that accept standard SFP transceivers.
