Harmonic 1GHz 4dB Transmitter SC/APC Connector

Harmonic’s Powerlink™ family of 1310 nm DFB laser transmitter modules is designed for advanced broadband networks. Powerlink II transmitters can operate alone in local distribution or narrowcasting applications and in combination with Harmonic’s externally modulated transmitter family for complete system solutions. The PWL 4100S transmitter modules are very compact with 10 transmitter modules fitting into a single three rack-unit high HLP 4200 platform via the HMC 4001 module carrier adapter. They are intelligent and can be set up  in  a matter  of  minutes by  means  of the  user-friendly  interface. Configuration  can  be done  in  three different  ways: via  the  HLP 4200WD  platform  front panel  menu,  the RF  adjustment  on the  module  front panel or the NET Watch™ Element Management System.

Advanced   predistortion    circuitry    enables   the state-of-the-art    Powerlink    1GHz   transmitter    to deliver    high   performance    with    RF   distortion suppression.   As   a  result,   system   designers  can achieve   very   high  carrier-to-noise   performance while    avoiding   receiver    overdrive    problems. Continuous high performance and reliability of the transmitters  are  assured by  a  microprocessor  and associated  firmware which  control  and  monitor all  vital   functions.   Monitored  functions   include laser   temperature  and   operating   point,  optical power and module temperature. The transmitter’s flat    frequency   response    and    wide   operating temperature range maximize overall broadband network performance.
