Product Description
Harmonic’s PWRLink II is a family of 1310 nm DFB laser transmitter modules. Designed for advanced broadband networks, PWRLink 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 PWL4900S transmitter modules are very compact with 10 transmitter modules fitting into a single three rack unit high HLP 4200 platform. The transmitter modules fit into the platform via the HMC 4000 module carrier adapter. They are intelligent and easy to configure by means of the user-friendly interface, allowing for set up in minutes. Set up is possible in three ways:
via the HLP 4200WD platform front panel menu, the RF adjustment on the module front panel, or the NETWatch™ Element Management System. Due to its advanced predistortion circuitry, the state-of-the-art PWRLink II transmitter delivers high performance with RF distortion suppression, enabling system designers to 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. The optical components within the PWRLink II transmitter module have been designed for ease-of-use and maintenance. The optical connector is mounted on a removable plate on the back of the unit. This feature facilitates simple cleaning of the connector, ensuring consistently high picture quality.
