The IRT-6580 is a 10/100/1000 Base-T Ethernet optical fibre link for point to point transmission using single mode fibre. It also incorpoartes 1000 Base-X optical transmission allowing it to interface to third party optical interfaces meeting the same standard.
The IRT-6580-EOT transceiver module is designed principally for use as a 10/100/1000 Base-T Ethernet to fibre optic transmission link, using 9/125μm single mode fibre, with optical paths losses up to 30dB1.
The EOT-4580 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 IRT-6580 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 LC/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 IRT-6580-EOT ‘s fibre output is 1000 Base-X and can be directly interfaced into an Ethernet switch with an equivalent optical interface.
The IRT-6580-EOT is designed to fit the openGear® standard 2RU frames which allow a mixture of cards from various manufacturers to be mounted within the same frame.
The DashBoard™ monitoring software is available as a free download.
NOTE: 1 – With the WDM option fitted for combined use on a single fibre, optical path loss is reduced by approximately 2dB.
NOTE: 2 – With the WDM option fitted, when operating as a pair, one IRT-6580-EOT must be fitted with a 1310nm transceiver and the other a 1550nm transceiver.
NOTE: 3 – An optical attenuator is required for optical path losses <9dB.
