SFP fiber transceiver CBO SFP-1G-ZX-NV-BO 1.25 Gbps single-mode 1310/1550 nm

CBO SFP-1G-ZX-NV-BO is a single-mode SFP fiber transceiver module that provides 1.25 Gbps data transfer for long-reach fiber links. The module fits standard SFP ports and delivers optical transmit/receive functionality with wavelengths typically in the 1310/1550 nm range. Its compact, hot-swappable form factor allows adding or replacing fiber ports in switches, routers and media converters without powering down equipment, enabling reliable gigabit fiber connectivity over extended distances.

Advantages

The transceiver supports a 1.25 Gbps data rate over single-mode fiber, designed for long-distance transmission. Compatibility with standard SFP slots ensures broad interoperability with networking equipment that accepts SFP form-factor optics. Hot-swappable installation simplifies maintenance and upgrades by allowing module replacement without interrupting system operation. The optical wavelength characteristics make it suitable for long-reach links and wavelength-multiplexed environments where 1310 nm or 1550 nm operation is required.

Suitable for

• Extending gigabit Ethernet or fiber channel links over single-mode fiber for long distances
• Adding fiber uplinks to switches and routers that have SFP ports
• Replacing faulty SFP modules in existing single-mode fiber installations
• Integration with media converters to convert copper ports to single-mode fiber

Key specifications

• Form factor: Small Form-factor Pluggable (SFP)
• Data rate: 1.25 Gbps
• Fiber type: Single-mode
• Typical wavelengths: 1310 nm / 1550 nm (transmit/receive)
• Connector type: LC duplex (standard for SFP single-mode optics)
• Hot-swappable: Yes
• Operating environment: designed for telecommunication and enterprise networking equipment

How to use

Power down is not required for insertion or removal when installed in equipment that supports hot-swappable SFP modules; however, follow the host device vendor instructions before handling optical modules. Insert the module into an empty SFP port until it latches, connect LC duplex single-mode fiber patch cables observing correct transmit/receive orientation, and verify link LED/activity on the host device. When replacing an existing module, remove the old module by releasing its latch and gently pulling it out, then install the new module and confirm link negotiation and signal integrity through the host management interface or status indicators.

Recommendations

Handle the fiber transceiver by its housing and avoid touching the optical connector end faces. Keep connector dust caps on when the module is not connected, use proper ESD protection during handling, and test the link performance after installation. Refer to the network equipment vendor documentation for supported fiber types, maximum link distances at the specified wavelengths, and any required configuration for optical transceiver compatibility.
