SFP Fiber Optic Transceiver CBO SFP-1G-EX 1.25Gbps Single‑Mode

CBO SFP-1G-EX is an SFP fiber optic transceiver module designed for 1 Gbps Ethernet links over single-mode fiber. The module conforms to standard SFP form factor and supports hot‑swapping for easy installation in switches, routers and media converters. It is intended to extend Ethernet connections over longer distances where copper cabling is impractical, providing a stable optical interface for telecom and enterprise network environments.

Advantages

The transceiver offers 1.25 Gbps nominal data rate with single-mode optics optimized for extended reach, enabling reliable point-to-point fiber connections. Its standard SFP form factor and hot-swap capability simplify replacement and upgrades without powering down equipment. Compatibility with a wide range of SFP-equipped network devices makes it suitable for mixed-vendor infrastructures while maintaining low power consumption and stable optical performance.

Suitable for

• Extending Ethernet links between network closets and data center racks
• Long-distance connections over single-mode fiber in campus or metro networks
• Interconnecting switches and routers across buildings or floors
• Integration with SFP-capable media converters and optical platforms

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Nominal data rate: 1.25 Gbps
• Fiber type: single-mode (SMF)
• Optical interface: standard single-mode optical connector (LC)
• Reach: designed for extended distance single-mode links (industry-standard ranges)
• Hot-swap: supported
• Power consumption: low-power SFP class
• Operating temperature range: suitable for standard telecom and enterprise equipment environments

How to use

Insert the CBO SFP-1G-EX into an available SFP port on a switch, router or media converter while the host device is powered on; the module supports hot-swapping so no shutdown is required. Connect a single-mode LC-terminated fiber patch cable to the module’s optical interface, ensuring correct transmit/receive orientation. Verify link status and diagnostics via the host device management interface and confirm that the negotiated speed and optical levels meet network requirements.

Recommendations

For reliable performance, use single-mode fiber with appropriate attenuation and connectors, maintain clean optical end-faces, and verify link budget for the required distance. Test transceiver compatibility with the host device and monitor optical power and diagnostic data where available. Replace or clean connectors if link issues occur.
