## Long description

The BlueOptics ONS-SI-155-SR-MM=-BO is an SFP fiber optic transceiver module designed for multimode optical links with a maximum data transfer rate of 155 Mbit/s. The module is silver-coloured, compact and lightweight (0.02 kg), and conforms to CE, RoHS and FCC standards. It uses an LC duplex interface and follows MSA-compatible SFP form-factor conventions, providing a standard physical connection for network equipment that supports 100BASE-FX style optical interfaces.
Advantages
The module offers a standardized SFP interface for simple hot-plug installation and compatibility with a wide range of network devices that accept MSA SFP modules. Its multimode design and optical LC duplex connector enable simultaneous transmit and receive channels on separate fibers, facilitating full-duplex optical links. Compliance with CE, RoHS and FCC ensures adherence to regulatory and environmental requirements while the lightweight metal housing supports reliable physical handling in rack-mounted and modular network environments.
Suitable for
 100BASE-FX multimode fiber links up to typical short-range distances
 Interconnects between switches, routers and optical patch panels supporting SFP
 Network ports requiring 155 Mbit/s optical transceivers with LC duplex
Key specifications
 Interface type: SFP (MSA compatible)
 Maximum data transfer rate: 155 Mbit/s
 Optical fiber type: multimode fiber (MM)
 Connector: LC duplex
 Product colour: silver
 Weight: 0.02 kg
 Regulatory compliance: CE, RoHS, FCC
How to use
Install the SFP transceiver into a compatible SFP slot on your network device while the device is powered down or following the vendor’s hot-swap procedure. Connect LC duplex multimode fiber patch cords to the module’s connector, ensuring correct transmit/receive alignment. Verify that the host device is configured for the intended 100BASE-FX/155 Mbit/s operation and that any required interface settings are enabled. Monitor link status indicators on the host device to confirm a successful optical connection.
Usage recommendations
Use multimode fiber patch cords and suitable patch panels rated for short-range 100BASE-FX links and avoid excessive bending of fibers. Confirm host equipment compatibility with MSA SFP modules and check whether the device supports any digital diagnostics features before relying on monitoring functions.
