The8F4to1conversionharnessiswiredwiththeLCduplexmatchedwiththeindividualtransmitandreceive
signalsdeliveredbyanySR4typetransceiver.IntheSR4transceiver,fibers1‐4areTXfibersand9‐12areRXfibers.
Intheharness,fibers1,
12;2,11;3,10and4,9arematchedtoprovideproperTX,RXalignmentattheduplexLC
