Network transceiver module MicroOptics SFP-SX-D — SFP, multimode SX

MicroOptics SFP-SX-D is an SFP network transceiver module designed for short-range multimode fiber connections. The module fits standard SFP cages in compatible switches and routers and supports duplex optical links over multimode fiber (SX). It is intended for short-reach Ethernet connectivity in data centers and enterprise networks where compact, hot-pluggable fiber links are required.

Advantages

The transceiver offers a compact SFP form factor for easy hot-swap installation without powering down equipment, enabling flexible uplink and interconnect options. Its multimode SX design delivers reliable short-range optical links suitable for server uplinks, switch-to-switch connections, and edge fiber runs. The product follows common SFP specifications for interoperability with a wide range of networking hardware.

Suitable for

• Short-range multimode fiber links in data center racks
• Server uplinks to switches and aggregation devices
• Switch-to-switch interconnects within the same building or campus
• Network edge fiber connections that require SX multimode optics

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Fiber type: Multimode fiber (MMF)
• Optical mode: Short-range SX
• Connector type: Duplex optical connector
• Hot-pluggable: Yes
• Typical use: Short-reach Ethernet and fiber interconnects

How to use

Insert the MicroOptics SFP-SX-D module into a compatible SFP port on a switch or router until it seats securely. Connect duplex multimode fiber cables to the module's optical connector, observing correct transmit/receive orientation. The module is hot-pluggable, but follow your equipment vendor's guidance for link negotiation and interface configuration to ensure proper speed and duplex settings. Monitor link status indicators on your networking device to confirm successful link establishment.

Recommendations

Use appropriate multimode fiber patch cords and clean connectors to maintain signal quality. Verify compatibility with the host device and configure interfaces according to network design. For best performance in short-range multimode deployments, keep fiber runs within the recommended distance for SX optics and avoid tight bends or stress on the fiber cable.
