Network media converter for 100Base-FX fibre

The TP-Link MC100CM converts 100BASE-FX multi-mode fibre to 100Base-TX copper and vice versa. It operates at 100Mbps in full-duplex mode on both ports. The unit complies with IEEE 802.3 and IEEE 802.3u standards. It is suited for extending a Fast Ethernet link over fibre up to 2km.

Thermals noise and power draw

Maximum power consumption is 2.4W supplied by an external DC 5V / 2A adapter. The device runs in a 0° ~ 50° C temperature range with 10-90% non-condensing humidity. No fan is fitted so operation is silent. The compact external form factor measures 3.7" x 2.9" x 1.1" and weighs .8.

Upgrade from copper-only links

This converter replaces a direct copper run when the distance exceeds 100m. It bridges a single RJ45 device to an SC multi-mode fibre link at 1310nm wavelength. The jump is worth it when you need to span up to 1.24 mile without adding a switch. It does not serve links that require gigabit speeds or single-mode fibre.

Questions about this item

How do I install the MC100CM and what step is often missed?

Connect the SC fiber cable to the SC port and the Cat.5 cable to the RJ45 jack, then plug in the external DC 5V / 2A power adapter; the step often missed is setting the FX port to Force or Auto transfer mode via the switch to match the link partner.

What maintenance or replacement will the MC100CM need later?

The external DC 5V / 2A power adapter is the only field-replaceable part; the converter itself has no moving components or user-serviceable modules.

What limit appears first during sustained use of the MC100CM?

The operating temperature ceiling of 50° C is the first limit; the unit draws 2.4 W maximum, so adequate airflow must keep it below that threshold during continuous operation.
