SFP Fiber Optic Transceiver CBO SFP-100-LC-SM20 100 Mbps, single-mode, 20 km

The BlueOptics SFP-100-LC-SM20 is a compact SFP fiber optic transceiver supporting a 100 Mbps data rate over single-mode fiber up to 20 km. Designed for insertion into compatible SFP slots, this module provides an LC optical interface for integration with switches, routers and media converters. It enables extension of network links between buildings, connection of remote devices and straightforward replacement of faulty or outdated modules while maintaining standard SFP form factor and compatibility.

Advantages

This transceiver offers a standardized LC connector and SFP form factor for broad compatibility with network equipment. A 20 km single-mode reach allows cost-effective extension of Ethernet links without additional active equipment. The 100 Mbps data support suits legacy and low-bandwidth links while consuming minimal power and occupying a small physical footprint. The device simplifies maintenance by enabling hot-swap replacement and reduces cabling complexity by using optical fiber for long-distance links.

Suitable for

• Extending Ethernet connections between buildings over single-mode fiber up to 20 km
• Connecting remote switches, routers or media converters in campus and industrial networks
• Replacing faulty or upgrading existing SFP modules with a 100 Mbps single-mode LC transceiver
• Low-bandwidth backbone links, monitoring ports and legacy network segments

Key specifications

• Data rate: 100 Mbps (full-duplex or half-duplex depending on host)
• Fiber type: single-mode
• Maximum transmission distance: up to 20 km
• Optical connector: LC
• Form factor: SFP (small form-factor pluggable)
• Transmission medium: single-mode optical fiber
• Typical power consumption: low (module designed for energy-efficient operation)

How to use

Insert the transceiver into a compatible SFP slot on the switch, router or media converter following the host device manufacturer’s guidelines. Connect an LC-terminated single-mode fiber patch cable to the module’s LC port, observing correct transmit/receive orientation. Configure the host port speed and duplex settings if required by the equipment; many hosts auto-negotiate 100 Mbps. Monitor link status indicators on the host device to verify successful link establishment. Remove the module by depressing the SFP latch or release mechanism before pulling it out to avoid damaging the socket.

Usage recommendations

Use quality single-mode fiber and LC patch cables rated for the intended distance to ensure reliable links. Avoid bending the fiber beyond its minimum bend radius and protect connectors from dust using dust caps when not connected. Confirm SFP compatibility with the host equipment and consult vendor documentation for any firmware or hardware restrictions related to third-party transceivers.
