Visint’s  HXT  Transceiver  Product  Family  is  a collection of high performance, cost effective XFP transceiver modules ideal for 10G SDH/SONET, 10G Ethernet and other fiber optic transmission applications. Designed to support data rates from

9.95Gbps  to  11.3Gbs  and  distances  up  to  80km, the  HXT  family  of  products  is  the  premier  choice for transceiver applications.

 

This transceiver contains both transmit and receive sections.  An  EML,  (1550nm,  ITU  channel  specific laser)  a  laser  driver  and  the  supporting  circuits constitute the transmit section while an APD or PIN ROSA and the supporting circuits form the receive section.        A        microcontroller          handles         the communications  between  the  module  and  the host  board  as  well  as  the  control  and  monitoring functions for both transmit and receive sections. A Clock  and  Data  Recovery  circuit  (CDR)  functions for both transmit and receive.

 

The transceiver module is fully compliant to the XFP MSA  standard  and  can  be  hot-plugged  into  the30-pin XFP connector on the host board. By limiting inrush   currents,   the   device   will   not   disturb   the operations   of   the   host   board.   The   high-speed electrical  interface  is  fully  compliant  with  the  XFI standard, providing transmission paths for the 10G signals.
