Amg Systems SFP-SM-1G-BX20-55 1G Single-mode Sfp 20km

Product Description

The AMG SYSTEMS SFP-SM-1G-BX20-55 is a single-mode, bidirectional (BiDi) small form-factor pluggable transceiver rated for 1 Gbps data throughput over a single fiber strand at distances up to 20 kilometers. Operating on a 1550 nm transmit wavelength, this module is designed for enterprise and industrial network infrastructure. It fits standard SFP slots on managed switches, media converters, and routers. Network technicians and low-voltage integrators install this module in applications where long-distance, single-fiber links are required, reducing fiber infrastructure costs while maintaining gigabit performance.

The SFP-SM-1G-BX20-55 is suited for enterprise backbone connections, campus fiber runs, and industrial network deployments where single-mode fiber is already in place. It is commonly used in media converter chassis and managed switches that support SFP-based uplinks. The 20 km reach makes it appropriate for inter-building links and distributed network segments. It is sold as a single unit and is intended for installation by qualified network technicians or low-voltage cabling professionals.

Key Features

• 1 Gbps single-mode fiber transceiver with up to 20 km reach
• BiDi single-fiber operation reduces fiber strand consumption by half
• 1550 nm transmit wavelength for standard single-mode BiDi pairing
• Standard SFP form factor fits a wide range of compatible switches and media converters
• Sold individually for flexible deployment and sparing

Compatibility

Designed for use in standard SFP-slot equipment including enterprise media converters, managed switches, and routers that support 1000BASE-BX single-mode BiDi SFP modules.

Installation Notes

Installation should be performed by a qualified network technician or low-voltage professional. Power down or disable the SFP port before inserting or removing the module to prevent damage to the host device or the transceiver. Use appropriate fiber cleaning tools on all connectors before mating, as contamination is a leading cause of link failure on single-mode fiber. Verify that the paired remote transceiver uses the complementary BiDi wavelength (1310 nm TX) to establish a valid link.
