Ricetrasmettitore SFP in fibra ottica BlueOptics JL745A-BO 550 m alluminio

The BlueOptics JL745A-BO is a single‑mode SFP transceiver in an aluminium housing designed for reliable 1.25 Gbps optical links over multimode fiber up to 550 meters. The module implements a 1000Base‑SX interface with LC duplex connector and uses 850 nm wavelength for transmit and receive. With a compact SFP form factor and a lightweight aluminium enclosure (approx. 20 g), this transceiver is intended for use in network switches, routers and storage systems that accept MSA‑compliant SFP modules.

Advantages

The transceiver follows MSA standards and is physically compatible with devices that support the original JL745A module. An aluminium housing offers mechanical protection and improved heat dissipation while keeping the module lightweight. It supports high‑speed Ethernet and related protocols at up to 1.25 Gbps over multimode fiber, and the LC duplex connector enables simultaneous transmit and receive channels. The module is suitable for installations where electromagnetic immunity of fiber is required and where a compact, standard SFP footprint is needed.

Key specifications

How to use

Insert the SFP transceiver into an empty SFP slot of a compatible switch, router or other network device according to the device manufacturer’s service instructions. Connect LC duplex multimode fiber patch cords to the TX and RX ports, ensuring the correct orientation for transmit and receive channels. After insertion, verify link status on the host device and configure the interface as required by your network settings. For accurate diagnostics, enable hardware support for digital diagnostic monitoring (DDM/DOM) on the host if available.

Recommendations

Use high‑quality multimode fiber (OM3/OM4 where applicable) and matching LC patch cords to achieve the specified reach and performance. Verify host device compatibility with MSA SFP modules and ensure firmware or driver policies do not block third‑party transceivers. For permanent installations, avoid excessive bending of fiber and maintain clean connector end faces to reduce optical loss.
