Optický SFP transceiver BlueOptics JL780A-BO 550 m hliník

The BlueOptics JL780A-BO is a fiber optic SFP transceiver designed for reliable 1.25 Gbps optical links over multi-mode fiber up to 550 meters. Housed in an aluminium casing and weighing approximately 20 grams, this SFP module uses an LC duplex connector and conforms to MSA form-factor expectations to ensure physical compatibility with standard SFP ports. The module integrates an 850 nm transmitter and receiver and is intended for use in network equipment that supports 1000Base-SX protocols.

Advantages

The aluminium housing provides mechanical durability and thermal stability while keeping weight low. Compatibility with the 1000Base-SX optical standard and MSA-compliant SFP form factor enables straightforward replacement or upgrade of existing SFP ports. Designed for multi-mode fiber and an 850 nm wavelength pair, the transceiver supports Ethernet and related high-speed applications up to 1.25 Gbps across distances up to 550 m. The compact SFP format allows flexible deployment in switches, routers and other networking devices.

How to use

Insert the BlueOptics JL780A-BO SFP module into a compatible SFP port on the network device until it clicks into place, observing proper orientation for the LC duplex connector. Connect an appropriate multi-mode fiber patch cable with LC duplex ends to the module and to the corresponding transceiver or patch panel. Ensure the host device supports 1000Base-SX and, if required, enable any software or firmware settings that accept third-party SFP modules. Verify link status and speed in the device management interface and perform basic link tests to confirm signal integrity.

Recommendations

Use high-quality multi-mode fiber and properly seated LC duplex connectors to achieve the rated 550 m range. If digital diagnostics (DDM/DOM) are required for monitoring, confirm that the host hardware and firmware support DDM functions for this SFP module. Keep the module and connectors free of dust and store unused transceivers in protective caps to avoid contamination.
