## Long description

The BlueOptics SFP-BXU35-20KM-CS-BO is a single-port SFP transceiver module designed for fibre-optic network links with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal enclosure with a silver finish, this compact module is intended for use in SFP-compatible switches, routers and media converters. With a lightweight design of 20 g and an MTBF of 1,000,000 hours, it is suitable for deployment in installations that require long-distance, point-to-point optical connectivity.
Advantages
This SFP transceiver provides a stable 1250 Mbit/s transmission over single-mode fiber and benefits from a robust metal housing that supports heat dissipation and mechanical protection. The module’s small form factor and standard SFP interface enable hot-pluggable installation in compatible network equipment. A high MTBF value indicates long operational reliability, reducing the need for frequent replacements.
Suitable for (tasks / use cases)
Long-distance single-mode fibre point-to-point links
Expansion of SFP ports on switches and routers
Data centre uplinks and campus backbone connections
Use in media converters and optical access equipment
Key specifications
Interface type: SFP
Maximum data transfer rate: 1250 Mbit/s
Form factor: Small Form-Factor Pluggable (SFP)
Housing material: metal, silver colour
Weight: 0.02 kg
Reliability: MTBF 1,000,000 hours
How to use
Power off or follow hot-swap procedures for the host device, then insert the BlueOptics SFP-BXU35-20KM-CS-BO into an available SFP slot until it seats securely. Connect appropriate single-mode fiber cables with compatible connectors to the module’s optical port, observing correct transmit/receive orientation. After insertion, verify link status and configure the host device’s port settings as required for 1250 Mbit/s operation and any specific optical parameters supported by the network equipment.
Usage recommendations
Install the module in an environment within the host equipment’s specified temperature range and maintain clean fiber connectors to minimise insertion loss. Use single-mode fiber rated for the intended distance and avoid bending the fiber beyond recommended radius to preserve signal integrity. For critical links, monitor the port status and plan for periodic inspections to ensure long-term reliability.
