Fiber optic transceiver module BlueOptics MP-S85123-3CDLM5-BO 550 m

The BlueOptics MP-S85123-3CDLM5-BO is a 1000Base-SX SFP fiber optic transceiver module designed for reliable short-range multimode fiber links up to 550 m. Housed in an aluminium enclosure and weighing approximately 20 g, this SFP module provides a compact, industry-standard SFP form factor with LC duplex connectivity and support for 1.25 Gbit/s Ethernet and similar high-speed protocols. The module incorporates 850 nm wavelength transmit and receive lasers suitable for multimode fiber and is compatible with a wide range of networking equipment that accepts MSA-compliant SFP modules.

Advantages

The module offers plug-and-play compatibility with SFP ports that support 1000Base-SX and follows MSA form-factor standards for broad interoperability. Its aluminium housing ensures mechanical durability and thermal dissipation in rack and chassis environments. Designed for multimode fiber, the transceiver supports bidirectional optical transmission over an LC duplex connector and provides stable operation for common LAN and storage networking tasks. Digital diagnostic monitoring (DDM/DOM) capability is available when supported by the host hardware, enabling real-time monitoring of supply voltage, laser bias current, optical output/input power and temperature.

Key specifications

How to use

Ensure the host device supports 1000Base-SX SFP transceivers and, if required, DDM/DOM functions. With the network equipment powered down or following hot-swap guidelines from the vendor, insert the SFP module into an available SFP port until it seats firmly. Connect an appropriate LC duplex multimode patch cable between the module and the remote transceiver or patch panel, observing correct TX/RX orientation. Power up the host and verify link status through the device management interface; when supported, read DDM values for link diagnostics. Follow vendor guidance for any required firmware or compatibility settings.

Recommendations

Use high-quality multimode fiber (OM3/OM4 as appropriate) and LC duplex patch cords to maximize the achievable link distance and signal margin. Verify that the host equipment explicitly supports 1000Base-SX SFP modules and, if you need remote diagnostics, confirm DDM/DOM compatibility. Avoid exposing the module to excessive mechanical shock or contaminating optical endfaces—clean connectors before mating and use dust caps when the module is not connected.
