TP TO FIBRE OPTIC USB SWITCHED CONVERTER

FEATURES :-

 

TECHNICAL DESCRIPTION: -

The 10/100 U-FX performs a single channel conversion from 10 Base T/100 Base Tx to 100 Base Fx. It has a high speed, non-blocking switch fabric, a high performance address lookup engine and a 1Mbit -frame buffer. The copper interface will automatically sense the Tx and Rx pairs and connect as appropriate, thereby eliminating special cable requirements. Auto negotiation is performed on the copper interface to determine the mode that the converter and its link partner can both achieve to give the highest data transfer rate. This is 100 full duplex (FD), 100 half duplex (HD),10FD and finally 10HD.

100 Tx systems use a three level code, which is scrambled to reduce EMC. It transmits a code as an idle. 10 base T systems use a phase encoded system only transmitting on data, at other times a short pulse, the idle, is transmitted.

The fibre interface conforms to the 100 Fx specification. This is a non-scrambled form of the binary 100 Tx code. Auto negotiation is not specified for fibre and hence must be preset using internal switches. The standard wavelength is 1300nm, which is not in the visible spectrum. It has the advantage that cables have less attenuation at this wavelength. Single mode options are available which will allow transmission over very long distances.

100 Base systems are only capable of transmission to 400m in a normal collision system. Due to minimum packet time, length and transmission delay. This is fundamental to CSMA systems. To operate above this limit a non-collision full duplex system must be used.

Mechanically the unit is housed in a small metal enclosure to limit EMC. Two variants are available; a simple box unit and a unit with flanges for universal fixing.
