Módulo SFP CBO SFP-1G-EX-GM-BO, 1 Gbit/s, 1250 Mbps, fibra monomodo, alcance 40.000 m

This CBO SFP-1G-EX-GM-BO is a 1 Gbit/s SFP optical transceiver designed for single-mode fibre links with a line rate of 1250 Mbps and a reach of up to 40,000 m. The module provides a compact, hot-pluggable interface for switches, routers and media converters, enabling long-distance uplinks and backbone connections in communication networks. It is intended for installations that require reliable optical connectivity over extended distances while minimising space in networking equipment.

Advantages

The transceiver supports long-reach single-mode transmission up to 40 km, offering stable 1 Gbit/s throughput at a 1250 Mbps line rate. Its small form-factor pluggable design allows hot-swap replacement without powering down host equipment, reducing maintenance windows. The module is compatible with standard SFP ports, saving rack space and simplifying upgrades of existing network infrastructure. Built for point-to-point optical links, it contributes to predictable latency and consistent performance on long-haul segments.

Suitable for

• Long-distance uplinks between data centres or distribution sites
• Backbone and metro fibre connections requiring single-mode optics
• Network equipment with SFP ports such as switches, routers and media converters
• Replacement or upgrade of existing 1 Gbit/s fibre transceivers

Key specifications

• Data rate: 1 Gbit/s (line rate 1250 Mbps)
• Fibre type: single-mode fibre
• Maximum reach: up to 40,000 m (40 km)
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Interface: optical (SFP port compatible)

How to use

Insert the SFP module into a compatible SFP slot on the switch, router or media converter until it clicks into place. Connect a single-mode fibre cable with the appropriate connectors to the module’s optical port, ensuring correct polarity and clean connector endfaces. After installation, verify link status and negotiate speed on the host device; no special drivers are required for standard SFP support. For maintenance, perform hot-swap replacement by removing the module using the release tab and inserting a replacement without powering down the host, if the equipment supports hot swapping.

Recommendations

Keep optical connectors clean and protected when not in use, use dust caps, and follow fibre handling best practices. Match the module to single-mode fibre and ensure link budget is sufficient for the span, taking into account connectors and splices. Verify compatibility with host equipment SFP port specifications and check link diagnostics after installation.
