Glasvezel-transceivermodule BlueOptics JD493A-BO SFP 550m

The BlueOptics JD493A-BO SFP 550m is a fiber optic transceiver module designed for multimode fiber links and short-range high‑speed data transmission. It implements the SFP (small form-factor pluggable) interface with an LC duplex connector and supports 1000Base‑SX optical signalling at 850 nm, enabling data rates up to 1.25 Gbit/s over distances up to 550 metres. The transceiver housing is aluminium and the module weighs approximately 20 g, making it suitable for use in switches, routers and other network devices that accept SFP modules.

Advantages

The BlueOptics JD493A-BO is manufactured to MSA-compliant physical and electrical specifications for SFP modules and is tested for compatibility with major hardware platforms. It uses industry-grade optical and electronic components to provide stable signal transmission, integrable LC duplex connectivity for simultaneous transmit/receive operation, and a compact aluminium form factor that simplifies installation and heat dissipation. The module supports standard digital diagnostic monitoring (DDM/DOM) when the host device exposes that functionality, allowing remote readout of operating parameters such as optical power and temperature.

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or other networking device while the device is powered down if recommended by the equipment manufacturer. Connect an LC duplex multimode fibre patch cable to the transceiver, observing correct transmit/receive orientation. Power on the host device and verify link status through the device’s management interface or LEDs. If the host supports digital diagnostics, access the DDM/DOM readings via the management system to monitor optical power, temperature and supply voltage for maintenance and troubleshooting.

Recommendations

Use high-quality multimode fibre patch cords and maintain proper bend radius to achieve the specified 550 m reach. Ensure the host device firmware supports third-party SFP modules and DDM/DOM if diagnostics are required. When installing or removing the module, follow electrostatic discharge (ESD) precautions and keep dust caps on unused fibre ports.
