FlexPoint transceiver for copper and fibre

The Black Box LMC1017A-MMSC converts between 10/100/1000Base-T copper and 1000Base-SX multimode fibre. It suits network teams extending LAN segments beyond standard copper limits without replacing switches.

Sustained line-rate conversion across the link

The module maintains gigabit throughput over the full 1804.46 ft multimode reach. Protocol handling covers Ethernet, Fast Ethernet and Gigabit Ethernet without throttling during continuous traffic.

Passive operation with flexible mounting

No active cooling is required and the unit draws power from the host port. Rail, rack or wall mounting options let installers place the converter where cabling is most convenient.

Questions about this item

How much power does the LMC1017A-MMSC draw when converting 1000Base-SX to 10/100/1000Base-T continuously?

The FlexPoint LMC1017A-MMSC is a media converter that requires an external power adapter; it supports rail-mountable, rack-mountable and wall-mountable power options.

What cabling and patch panels must I already have to use the 1000Base-SX port on this transceiver?

You need multimode fibre patch cords with SC connectors and a compatible SC patch panel or switch port for the 1000Base-SX link.

Will the LMC1017A-MMSC link at 1000Base-SX with legacy 100Base-FX equipment over the same fibre?

No, the SX port operates at Gigabit Ethernet speeds only; it does not negotiate down to Fast Ethernet on the fibre side.
