Convertitore di media Microsense MS400249 — 1x10/100/1000Base-T su 1x1000Base-X fibra ottica

Microsense MS400249 is a bridging media converter that connects a copper Ethernet port (1x10/100/1000Base-T) to a single fiber uplink (1x1000Base-X). It converts electrical signals on twisted-pair copper to optical signals for gigabit fiber links, enabling network extension, backbone connections, or segment isolation. The device is intended for integrating fiber segments into existing copper networks and providing stable gigabit connectivity over longer distances while maintaining standard Ethernet framing and link negotiation on the copper side.

Advantages

The Microsense MS400249 provides transparent media conversion between 10/100/1000Base-T and 1000Base-X without altering network protocols or requiring configuration. It supports automatic MDI/MDI-X crossover on the copper interface and standard link speed negotiation, enabling simple plug-and-play deployment. By converting to fiber it extends link distances and reduces susceptibility to electromagnetic interference while keeping a compact footprint suitable for rack or desktop placement.

Suitable for (tasks / use cases)

• Extending Ethernet networks over longer distances using fiber backbone links
• Connecting copper-based switches or servers to fiber distribution or aggregation equipment
• Isolating network segments or creating fiber uplinks in small to medium office environments
• Migrating parts of a network to fiber while retaining existing copper endpoints

Key specifications

• Copper port: 1x 10/100/1000Base-T (RJ-45) with auto-negotiation and auto MDI/MDI-X
• Fiber port: 1x 1000Base-X (single-mode or multimode compatibility depends on fiber transceiver type used)
• Function: Layer 1 media conversion (transparent bridging)
• Data rate: Supports up to 1 Gbps on fiber and copper links
• Operation: Plug-and-play, no configuration required

How to use

Install the Microsense MS400249 by connecting the RJ-45 copper Ethernet cable to the 10/100/1000Base-T port and the appropriate fiber cable to the 1000Base-X port using a matching transceiver or connector type. Power the unit according to the manufacturer's instructions and verify link LED indicators on both ports to confirm established connections. The device operates transparently at Layer 1; connected hosts and switches will see the link as a standard Ethernet connection and negotiate speeds and duplex on the copper side as usual.

Recommendations

Use matching fiber types and transceivers for the 1000Base-X port (single-mode or multimode) and verify connector compatibility. Place the media converter in a ventilated location, avoid exposure to strong electromagnetic sources near the copper cable run, and use quality patch cables to maintain signal integrity. For critical links, monitor link LEDs and consider redundant paths at the network design level.
