GENERAL:

The EOT-4581 transceiver module is designed principally for use as a 10/100/1000 Base-T Ethernet to fibre optic transmission link, using 9/125?m single mode fibre, with optical paths losses up to 30dB1.

The EOT-4581 conforms to the IEEE 802.3i, 802.3y and 802.3ab standards for Ethernet over CAT-5 cable, and the IEEE 802.3z (1000 Base-X) standard for Gigabit Ethernet over optical fibre.

The Ethernet port has automatic MDI/MDI X detection, this detects whether the Ethernet interconnect cable is a straight through or cross over type and automatically switches itself to accommodate, and will automatically select the link speed of the connected network (10/100/1000 Mb/s).

The EOT-4581 is also able to support Jumbo frames, which are Ethernet frames with more than 1500 bytes of payload data, up to a maximum frame size of 10,240 bytes.

A fibre transceiver is incorporated on the one card allowing bi directional communication over a pair of SC/PC single mode fibre optic cables.

Optionally a 1310/1550nm WDM1,2 optical combiner can be fitted to allow for combined use on a single fibre.

As well as being able to be used as a pair for a point to point fibre link, the EOT 4581's fibre output is 1000 Base X and can be directly interfaced into an Ethernet switch with an equivalent optical interface.

The EOT-4581 is a Eurocard module designed to fit IRT's 1RU frame or IRT's 4000 series frames for use with IRT's SNMP system and may be used alongside any other of IRT's Eurocards.


NOTE:1 With the WDM option fitted, optical path loss is reduced by approximately 2dB.
          2 With the WDM option fitted, when operating as a pair, one EOT-4581 must be fitted with a
             1310nm transceiver and the other a 1550nm transceiver.
          3 An optical attenuator is required for optical path losses <9dB.
