SFP transceiver module CBO SFP-1G-EX-NV-BO 1.25 Gbit/s single‑fiber 1250 Mbit/s

The CBO SFP-1G-EX-NV-BO is a hot-pluggable SFP transceiver module designed for single-fiber optical links at 1.25 Gbit/s (1250 Mbit/s). It fits standard SFP slots to extend optical networks and interconnect devices such as switches, routers and media converters. The module supports single-fiber operation, enabling duplex transmission over one fiber using separate wavelengths, and is intended for applications where compact, replaceable fiber optics are required.

Advantages

This SFP transceiver offers easy installation through a hot-pluggable SFP form factor and broad compatibility with devices that accept standard SFP modules. It provides reliable optical link performance at 1.25 Gbit/s and supports single-fiber installations to reduce cabling complexity. The compact design allows straightforward replacement or upgrade of existing ports without reconfiguring the host device.

Suitable for

• Connecting switches and routers over single-fiber optical links
• Extending network segments with media converters and fiber repeaters
• Replacing or upgrading SFP ports in rack-mounted and compact network equipment

Key specifications

• Data rate: 1.25 Gbit/s (1250 Mbit/s)
• Form factor: SFP (hot-pluggable)
• Fiber type: single-fiber operation (single strand with wavelength multiplexing)
• Application: serial optical data links for networking equipment

How to use

Insert the transceiver into an available SFP slot on the host device until it seats firmly. Connect the appropriate single-fiber optic cable, ensuring correct connector type and polarity for single-fiber operation. After connection, verify link status and configure the host device interface if necessary to enable the 1.25 Gbit/s optical port. To remove, power down the link if required by the host and gently pull the module out using the release mechanism.

Recommendations

Use factory-certified single-fiber patch cords and verify wavelength compatibility when deploying in mixed-vendor environments. Ensure the host device supports SFP modules and the intended single-fiber transmission method. Protect transceiver and fiber connectors from dust and mechanical stress; store unused modules with dust caps.
