## Summary description

The BlueOptics JL781A-BO is a fiber optic SFP transceiver module designed for high-speed data transmission over long distances up to 10000 m. It features an aluminum housing for durability and weighs only 20 g. This module is ideal for network applications requiring reliable connectivity.

## Long description

The BlueOptics JL781A-BO SFP 10000 m is a fiber optic transceiver module designed for long-distance single-mode connections. Housed in aluminium and weighing approximately 20 g, this SFP module implements a standardized LC duplex interface and is intended for integration into network equipment that accepts SFP form-factor transceivers. It supports optical transmission over distances up to 10,000 metres and is suitable for high-speed point-to-point links where reliable fibre connectivity is required.
Advantages
The aluminium enclosure provides mechanical durability and improved thermal dissipation while keeping the module lightweight. Compliance with SFP interface standards ensures broad interoperability with compatible network switches, routers and storage systems. Designed for single-mode fibre operation with LC duplex connections, the module offers stable optical links over extended distances and a compact footprint that preserves port density in network racks.
Suitable for
Long-distance single-mode fibre links up to 10 km
Interconnection of switches, routers and storage systems with SFP ports
Upgrading or replacing SFP transceivers in existing fibre networks
Key specifications
Form factor: SFP (Small Form-factor Pluggable)
Maximum transmission distance: up to 10,000 m on single-mode fibre
Connector type: LC duplex
Housing material and colour: aluminium, aluminium-coloured
Weight: approximately 0.02 kg
How to use
Install the module into an available SFP port on compatible network hardware while the device is powered off or according to the vendor's hot-plug guidelines. Connect LC duplex single-mode fibre patch cords to the module’s LC connectors, ensuring correct transmit and receive orientation. After insertion and fibre connection, verify link status and signal levels via the host device management interface. Follow the host equipment documentation for any required configuration to enable the optical port.
Usage recommendations
Use single-mode LC duplex patch cords and, where possible, route fibres through patch panels or protective conduits to maintain connector cleanliness and mechanical integrity. Before deployment, confirm compatibility with the intended host device and, if available, enable any digital diagnostic functions supported by the system to monitor optical parameters and ensure stable operation.
