GLC-ZX-SMD

The Cisco GLC-ZX-SMD is a transceiver module designed to extend fiber optic communication distances. It converts electrical signals into optical signals at a 1550nm wavelength, making it suitable for long-haul data transmissions over single-mode fiber.

Often found in enterprise and service provider networks, this module suits installations requiring connections beyond typical short-range distances, such as campus backbones or metropolitan networks. Network engineers and IT professionals use it to maintain stable links over extended fiber runs.

Key Features

• Operates at 1550nm for enhanced reach across single-mode fiber
• Supports distances up to 80 kilometers without signal degradation
• Compatible with Gigabit Ethernet standards ensuring broad interoperability
• SFP form factor allows easy installation and replacement
• Designed for stable performance in various network environments

This transceiver module is commonly deployed in environments where long-distance fiber connections are necessary but without the complexity of more expensive equipment. It plays a reliable role in backbone links and inter-building connectivity where maintaining signal integrity over distance is critical.
