SFP fiber transceiver CBO SFP-BIDI-1550-10 1550 nm single-fiber bidirectional, up to 10 km

The BlueOptics CBO SFP-BIDI-1550-10 is a compact SFP fiber transceiver designed for bidirectional single-fiber links at 1550 nm with a reach of up to 10 km. Intended for insertion into standard SFP slots on switches, routers and media converters, this module enables duplex communication over a single strand of fiber by using wavelength-division at each end. The transceiver supports point-to-point connections, network extension and restoration scenarios where fiber availability is limited or single-fiber routing is required.

Advantages

This SFP transceiver reduces physical fiber requirements by providing bidirectional data transfer over one fiber while maintaining compatibility with standard SFP ports. Its 1550 nm wavelength and up-to-10 km reach suit metropolitan and campus links. The compact SFP form factor allows easy hot-swap installation and integration into existing network equipment without additional configuration changes on most platforms.

Suitable for

• Extending network links between buildings or floors where only one fiber strand is available
• Point-to-point connections between switches, routers and media converters
• Restoration or temporary links when fiber resources are limited
• Small to medium enterprise and campus backbone segments

Key specifications

• Optical wavelength: 1550 nm
• Fiber type: single-fiber bidirectional operation (single strand)
• Maximum reach: up to 10 km (depending on fiber quality and link budget)
• Form factor: SFP (hot-swappable)
• Compatible interfaces: standard SFP slot on switches, routers and media converters
• Transmission: duplex over one fiber using different wavelengths for TX and RX

How to use

Insert the transceiver into an available SFP slot on the networking device until it seats securely; most equipment will detect the module automatically. Connect a single optical fiber between paired transceivers, ensuring proper orientation and that the remote device uses the complementary wavelength for bidirectional operation. Verify link status via the device’s management interface or status LEDs and confirm that link speed and duplex settings match on both ends where applicable.

Usage recommendations

Use clean connectors and appropriate fiber patch cords rated for single-fiber bidirectional links. Check link budget and attenuation for the chosen fiber path to ensure reliable operation up to 10 km. When mixing vendor equipment, verify compatibility with the host device’s SFP transceiver support list and enable any required firmware settings for third-party modules.
