SFP transceiver CBO J9142B-BO 1250 Mbit/s, 20,000 m reach

The SFP transceiver CBO J9142B-BO is a compact, hot-pluggable module engineered for single-channel fiber links with a data rate of 1250 Mbit/s and an optical reach of up to 20,000 meters. Manufactured by BlueOptics for use in equipment with SFP ports, this transceiver supports long-distance connections over fiber optic infrastructure and is suitable for deployment in service provider networks, campus backbones and metropolitan links. The module is designed for straightforward replacement or upgrade of compatible SFP ports without modifying existing hardware.

Advantages

The transceiver offers stable 1250 Mbit/s throughput and extended optical reach up to 20 km, enabling long-haul fiber connections between sites. Its hot-pluggable SFP form factor minimizes downtime during installations or replacements and simplifies inventory by using a common small form-factor module. The unit is compatible with standard SFP sockets and supports reliable optical link performance over single-mode fiber.

Suitable for

• Service provider long-distance links and dark-fiber connections
• Campus backbone and inter-building fiber connections
• Metropolitan area networks (MAN) and ring topologies
• Interconnecting switches, routers and optical network equipment

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1250 Mbit/s
• Maximum optical reach: up to 20,000 meters (20 km) over single-mode fiber
• Interface type: optical fiber (single-mode)
• Hot-pluggable design for in-service module replacement
• Typical operating environment: indoor telecom and data center installations

How to use

Insert the SFP module into an available SFP slot on compatible network equipment while the device is powered on or following the vendor’s recommended procedures. Connect single-mode fiber cables to the transceiver’s optical ports using appropriate connectors and ensure correct polarity. After insertion, confirm link status through the host device management interface and verify optical levels and link parameters. For replacements, remove the existing module and insert the BlueOptics SFP, allowing the system to detect the new transceiver automatically.

Usage recommendations

Use single-mode fiber with suitable connectors and maintain clean fiber end-faces to ensure optimal link performance. Verify that the host equipment supports SFP modules with 1250 Mbit/s operation and confirm fiber attenuation and link budget for reaches approaching 20 km. Store unused modules in anti-static packaging and avoid exposure to extreme temperatures or mechanical shock during handling.
