SFP transceiver CBO SFP-GLS-20A-A 20 km 1310 nm single-mode

SFP transceiver CBO SFP-GLS-20A-A 20 km 1310 nm single-mode is a compact optical module for use in devices with SFP ports. Operating at a wavelength of 1310 nm, this single-mode transceiver supports point-to-point links with a maximum reach of 20 km, enabling extension of Ethernet and fiber-based networks in enterprise and telecom installations. The module is designed to fit standard SFP cages and interfaces transparently with compatible switches, routers and media converters.

Advantages

The transceiver provides stable single-mode transmission over distances up to 20 km while maintaining low power consumption and compact SFP form factor. It supports hot-pluggable operation and standard optical interfaces for straightforward integration into existing network equipment. Constructed to industry specifications, the module delivers predictable optical performance and interoperability with a wide range of SFP-compatible devices.

Suitable for

• Extending LAN and MAN links between switches and routers
• Point-to-point fiber connections in enterprise and telecom networks
• Connecting media converters and optical distribution equipment
• Long-distance uplinks for access and aggregation layers

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Fiber type: single-mode fiber
• Wavelength: 1310 nm
• Maximum transmission distance: up to 20 km (depending on fiber type and link budget)
• Data rate: compatible with standard SFP line rates (consult equipment for supported speeds)
• Optical interface: LC duplex
• Hot-pluggable: yes

How to use

Insert the SFP transceiver into an available SFP slot on a switch, router or media converter until it seats firmly. Connect single-mode fiber with LC duplex connectors, ensuring correct transmit/receive orientation. Power on the network equipment and verify link status via device indicators or management interface. Observe fiber handling precautions to avoid contaminating or damaging connector end faces, and use a compatible fiber patch cable and transceiver settings in the host device.

Recommendations

For reliable long-distance links, use single-mode fiber with appropriate attenuation and dispersion characteristics, keep connectors clean with proper inspection and cleaning tools, and confirm link budget and supported data rates in the host equipment. Replace the module if optical power levels or link stability fall outside expected ranges.
