The DFB laser's wavelength is stabilized and aligned to one of eight wavelengths on the ITU grid with 200 GHz (1.6 nm) spacing. By using Dense Wavelength Division Multiplxing (DWDM), multiple return path signals can be carried on a single fiber. The HLD 7205 transmitters can operate alone or in combination with Harmonic's METROLink family of gain flattened optical amplifiers, and DWDM multiplexers and demultiplexers for complete system solutions. The HLD 7205 transmitter modules are compact, intelligent and easily configurable by means of the user-friendly interface, allowing for set-up in minutes. The transmitters can be set up via the HLP 4200WD platform front panel menu, the module front panel function slide switch and set-up adjustment, or via the NETWatchTM Element Management System. 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, module temperature and composite RF drive level. The optical components within the HLD 7205 transmitter module have been designed for ease-of-use and maintenance. The module features an optical connector on a removable plate on the back of the unit, facilitating simple cleaning and maintenance. The innovative design of the HLD 7205 transmitter and Harmonic's complete line of METROLink products offer many advantages to address the needs of today and tomorrow, making it the industry's leading solution for return path digital services: DWDM offeres high-performance alternative to frequency stacking. Shares common platform with the METROLink gain flattened EDFA, forward path transmitter and wavelength selected broadcast transmitter. Integrated element management with SNMP compatibility. Microprocessor control of all key parameters provides consistent and optimum product performance and monitoring. 200 MHz bandwidth provides flexibility in RF channel allocation. Unparalleled flat frequency response provides high performance and efficient system integration. Integrated RF pre-amplifier reduces transmitter drive level requirements. Simple "plug and play" operation reduces time and cost of installation. Applications Two-way HFC system High-quality replacement for frequency stackers Targeted digital services (Video on Demand (VOD), Internet, cable telephony, IP telephony)
