## Summary description

CBO MFB-F40 is a fiber optic transceiver designed for single-channel data transmission at 1.25 Gbps over distances up to 40 km. It provides reliable optical connectivity for network equipment supporting compatible SFP-style modules. Suitable for telecom, ISP backbone links and enterprise fiber runs where long-distance, low-latency links are required.

## Long description

CBO MFB-F40 1.25 Gbps 40 km is a single-channel fiber optic transceiver designed for long-distance optical links. The module supports 1.25 Gbps data rate and is intended for installation in equipment that accepts SFP-style fiber modules. It is suitable for establishing point-to-point optical connections over single-mode fiber up to 40 km, offering a compact form factor for telecom, ISP backbone and enterprise network infrastructure.
Advantages
The transceiver provides stable single-channel transmission at 1.25 Gbps with a nominal reach of up to 40 km, enabling long-distance links without intermediate amplification. Its SFP-compatible form factor allows hot-pluggable installation in a wide range of switches, routers and media converters. The design emphasizes reliable optical coupling and compatibility with standard single-mode fiber, ensuring predictable performance in backbone and access networks.
Suitable for
 Telecommunication point-to-point links over single-mode fiber
 ISP backbone connections and metro aggregation
 Enterprise campus or data center fiber runs requiring long reach
 Replacement or upgrade of SFP fiber ports in network equipment
Key specifications
 Data rate: 1.25 Gbps single-channel
 Maximum transmission distance: up to 40 km over single-mode fiber
 Interface: SFP-compatible hot-pluggable module
 Fiber type: single-mode (SMF)
 Application: point-to-point optical links for telecom, ISP and enterprise networks
How to use
Install the transceiver into an SFP slot on compatible network equipment while the device is powered on or off according to the host’s guidelines; the module supports hot-plug operations on most systems. Connect a single-mode fiber patch cable to the optical port, ensuring correct alignment and clean connectors to maintain signal integrity. Configure the host port settings as required for a 1.25 Gbps link and verify link status and diagnostics through the network device management interface.
Usage recommendations
Use certified single-mode patch cords and maintain clean connector endfaces to minimize loss. Verify compatibility with the host device's SFP module list and configure appropriate interface parameters (speed, duplex and administrative state) in the network equipment. For runs approaching 40 km, check link budget and consider dispersion and connector/splice losses during planning.
