Fast Ethernet to Optical

Media Converter

Datasheet

Media Converter Datasheet Revision A

DESCRIPTION

Firecomms Fast Ethernet CAT5 to optical Media

Converter accepts standard 100 Mbps Fast Ethernet

traffic from 100 Base-Tx source over CAT5

connected via a standard RJ45 jack. Ethernet traffic

is fed to a 100 Base-Fx compatible PHY IC to a

Firecomms Fast Ethernet fiber optic transceiver

(Tx + Rx) housed in an OptoLock® connector format.

Auto-MDIX, a standard feature on the PHY IC used

in this media converter, automatically corrects for

cable cross-over. The PHY provides the optimum

data handling conditions for streaming video with

excellent quality of service (QoS). This link is

particularly suitable for applications such as IPTV

delivered over a POF physical layer. The Firecomms

RCLED based transceiver provides high levels of light

coupling into fiber with short rise and fall times. This

enables Ethernet signalling over large core POF.

The media converter is a plug and play device.

Therefore, it does not require any firmware, driver

or external software to operate.

The media converter may be used wherever it is

required to convert Fast Ethernet traffic from

copper cables to an optical cable. A pair of media

converters may be used to form an optical “bridge”

between two copper-based networks. A single

media converter may be used to link a unit already

equipped for Plastic Optical Fiber into a copper

cable-based network.

Note: DC power supplies, USB power cables, POF cables and CAT5

cables are not included in the above part number. Please see

accessories section on page 7 for more information.
