Comnet SFP-20B 100mbps 1550nm 60km Single Mode Sfp

Product Description

The COMNET SFP-20B is a small form-factor pluggable (SFP) fiber optic transceiver module designed for single-mode fiber network infrastructure. Operating at a wavelength of 1550 nanometers with a data rate of 100 Mbps, this module supports transmission distances up to 60 kilometers over single-mode fiber. It is intended for installation by network engineers and low-voltage technicians working on fiber optic communication systems where long-reach connectivity is required. The compact SFP form factor plugs directly into compatible SFP-slot network switches, media converters, and similar equipment.

The SFP-20B is suited for commercial and industrial fiber optic network deployments where extended single-mode runs are needed. Typical applications include campus backbone connections, building-to-building fiber links, municipal networks, and security or surveillance communication infrastructure. It is sold individually and fits SFP-compatible slots in network switching and transmission equipment commonly found in structured cabling and fiber optic system installations.

Key Features

• 1550nm transmit wavelength optimized for long-distance single-mode fiber runs
• 100 Mbps data rate suitable for Fast Ethernet and similar applications
• 60-kilometer reach over single-mode fiber
• Standard SFP form factor for broad equipment compatibility
• Fiber optic connectivity category hardware

Compatibility

Designed as an OEM-style replacement or upgrade SFP module for use in network switches, media converters, and other equipment featuring standard SFP slots that support single-mode fiber at 100 Mbps.

Installation Notes

Installation should be performed by qualified low-voltage or network technicians familiar with fiber optic handling procedures. Power down or disable the host port before inserting or removing the SFP module to avoid optical or electrical damage. Handle fiber end-faces with care and keep dust caps in place when the module is not connected. Follow structured cabling standards and any applicable local codes when routing and terminating single-mode fiber cables.
