Mrežni medijski konverter Longshine LCS-C842MT

The Longshine LCS-C842MT is a compact network media converter designed to bridge copper-based 10/100Base-TX segments and fiber-based 100Base-FX links. It supports multi-mode and single-mode fiber connections, operates in full or half-duplex, and provides a cost-effective way to extend network reach up to 2 km with multi-mode fiber and up to 60 km with single-mode fiber depending on module and fiber type. The device complies with IEEE 802.3/802.3u standards and carries FCC Class A and CE approvals.

Advantages

The LCS-C842MT offers plug-and-play operation with auto-negotiation (NWay) and automatic MDI/MDI-X detection on the RJ-45 port, simplifying installation and reducing configuration time. Built-in Link Fault Signaling (LFS) provides immediate indication of link failures and can switch traffic to a redundant path. Remote and local loopback tests, enabled by DIP switches, facilitate quick troubleshooting without physical inspection. Multiple power options and clear LED indicators support flexible deployment and easy status monitoring.

Suitable for

• Extending Ethernet networks over fiber between buildings or to remote closets
• Migrating or upgrading copper-based LANs to fiber links
• Small office or desktop installations requiring compact media conversion
• Applications needing link redundancy or simple diagnostic testing

How to use

Install the LCS-C842MT on a desktop, wall-mount location, or in a compatible multi-unit chassis. Connect the copper Ethernet cable to the RJ-45 port and the fiber cable to the FX port using the appropriate transceiver type for multi-mode or single-mode fiber. Power the unit using the internal or external power supply option. The device will perform auto-negotiation and configure link settings automatically; use the DIP switches to enable loopback tests or to change specific device options. Monitor LEDs for link status and LFS indications.

Recommendations

For reliable long-distance links choose the correct fiber type and transceiver compatible with the LCS-C842MT; verify fiber losses and use single-mode optics for distances beyond 2 km. Use the LFS feature in environments where rapid failover to a redundant link is required, and run loopback tests during installation to confirm end-to-end connectivity.
