Kuitu-SFP-lähetin-vastaanotin BlueOptics ONS-SI-GE-SX-BO 550 m

The BlueOptics ONS-SI-GE-SX-BO is a fiber optic SFP transceiver for 1000Base-SX multimode links, designed to transmit data at gigabit speeds over distances up to 550 metres. The module uses an LC duplex connector and operates with 850 nm transmitter and receiver wavelengths. Housed in aluminium and weighing approximately 20 g, the transceiver follows MSA specifications and is suitable for integration into network equipment that supports 1000Base-SX SFP modules.

Advantages

The transceiver offers compatibility with a wide range of network hardware that accepts 1000Base-SX SFPs, providing a compact SFP form factor with an aluminium casing for mechanical robustness and lightweight handling. Support for multimode fiber and LC duplex connections allows simultaneous transmit and receive channels over a single duplex fiber pair. Digital Diagnostic Monitoring (DDM/DOM) support enables real-time monitoring of supply voltage, laser bias current, output power, received power and temperature when the host device supports this function.

Suitable for

• Short-reach multimode fibre connections in enterprise LANs
• Switch-to-switch and switch-to-server uplinks up to 550 m
• Storage area network links and SAN front-end connections supporting 1 Gbps
• Upgrading or replacing compatible 1000Base-SX SFP modules in supported hardware

Key specifications

• Interface type: SFP (small form-factor pluggable)
• Data rate: up to 1.25 Gbps (1000Base-SX)
• Wavelength: 850 nm transmitter and receiver
• Maximum reach: up to 550 metres over multimode fiber
• Connector: LC duplex
• Housing material and colour: aluminium
• Weight: approx. 0.02 kg
• Supports Digital Diagnostic Monitoring (DDM/DOM) per SFF-8472 when supported by host hardware

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or other network device with the connector aperture oriented according to the host device instructions. Connect LC duplex multimode patch cables to the module, ensuring correct transmit-to-receive pairing. Verify link status on the host device and, if available, check DDM/DOM parameters through the device management interface to confirm optical power and temperature readings. Follow standard hot-plug handling precautions and ESD protection when inserting or removing the module.

Recommendations

For reliable performance, use multimode fiber with appropriate attenuation characteristics and quality LC patch cords. Confirm that the target hardware officially supports 1000Base-SX SFP modules and that firmware or software settings do not restrict third-party transceivers. Use DDM/DOM monitoring for proactive maintenance and keep connectors clean to minimise insertion loss and reflections.
