## Summary description

The BlueOptics MP-S85123-3CDLM5-BO is a fiber optic SFP transceiver module designed for high-speed data transmission over distances up to 550 m. It features an aluminum housing, weighs only 20 g, and is ideal for networking applications requiring reliable performance. This module is compatible with various SFP interfaces, making it versatile for different setups.

## Long description

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.
Suitable for
Gigabit Ethernet links over multimode fiber in campus and data center networks
Switch-to-switch, switch-to-server and switch-to-storage connections within the specified 550 m range
Storage area networks and Fibre Channel over Ethernet deployments using SFP ports
Network repairs, upgrades, or spare-parts stocking where MSA-compatible SFP modules are required
Key specifications
Form factor: SFP (small form-factor pluggable)
Data rate: up to 1.25 Gbit/s (1000Base-SX)
Optical wavelength: 850 nm (TX and RX)
Connector: LC duplex
Fiber type: multimode fiber (MMF)
Maximum link distance: up to 550 m (dependent on fiber type and conditions)
Housing material and colour: aluminium, aluminium colour
Weight: approx. 0.02 kg
Digital diagnostics: supported when host hardware provides DDM/DOM support
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.
Usage 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.
