HIGH-PERFORMANCE OTDR MODULE RELEASED FOR USE WITH REMOTE FIBRE TEST SYSTEMS


high-performance optical time- domain reflectometer (OTDR) module has been released by Yokogawa for use with remote fibre-test systems (RFTS).


A


An RFTS is a test system designed to improve the efficiency of operation and maintenance


management of optical fibre lines installed at a fibre-optic cable termination station by constantly monitoring individual fibres in the cable using the OTDR technology for continuous measurements. The system indicates the failure location on an electronic map and notifies the maintenance staff by means of e-mail or telephone.


As a result, it speeds up the identification and location of


failures (such as increased loss, fibre


breaks and water ingress) and facilitates restorative maintenance. It also enables the maintenance centre to test the installed


equipment as a remote manual test during cable installation.


The ability to perform automatic testing of multiple fibres at once saves installation labour time and costs and reduces the work period. Today’s regulatory regime has made it more important than ever for telecom carriers to proactively

monitor and maintain their fibre networks. In particular, the huge penalties specified in service level agreements and quality of service commitments give carriers financial incentives to invest in maintaining their fibre networks.


Yokogawa’s AQ7 OTDR module is The hardware


of the AQ7277B


280 OTDR, with its based on


short dead zone (0.6m typical) and high dynamic range (up to 50dB). www.yokogawa.com

MLX81112 and dual-channelMLX81115 are able to help drive LEDs via constant current sources. High levels of


integrationmean that it is possible to rationalise LINRGBmodule designs by combining a singlemixed-signal chip with less than half the passive components compared to similar

code. Additionalmemory resource is provided by a 16kByte ROM(which contains the necessary RGBmix algorithms and LINdriver), a 2kByte RAMand a 380Byte EEPROM.Other on-board functionality comprises a 10- bit analogue-to-digital converter (with integrated pre-divider), a LINprotocol controller, a LINtransceiver, four configurable constant current outputs and four 16-bit PWMoutputs.
