1, the space and A 】 HY-7330 A series of optical receiver is our field development and production of A new generation of HFC network light node equipment.
2, the series products fully meet the "GY/T185-2002 radio, film and television industry standard" the design requirements, the computer aided design, microwave simulation software simulation, some functional way according to the module combination, two-way design, 1 GMHz working platform, excellent with inner flatness, bandwidth from 750 MHz-862 MHz can smooth upgrade;
3, 1310 nm wavelength compatible and 1550 nm, made of high quality high sensitivity light detectors and PIN tube core photoelectric integration module, make the photoelectric convert better matching, and ensure the power circuit of the heat;
4, rf circuit using PHILIPS imported amplifier module (optional gallium arsenide module), to ensure that the product performance index and reliability; Light power level indicator for eight level shows, convenient engineering personnel to understand the size of receiving light power, which makes it easy to the engineering personnel for network commissioning;
5, signal channel and the combination of the power supply prevents thunder measures, maximum limit avoids the lightning strikes on equipment damage; The function is all ready, parts are using inserted type structure, put the needle, sockets are gold-plated copper insurable property and good contacts;
6, output form can use branch or distribution, convenient technical personnel design, installation, commissioning;
7, choose professional manufacturer produces high reliable power supply of switching power supply, 150-280 V (optional 35-95 V) of wide working voltage of the influence of the power to lowest;
8, function panel adopts the high quality aluminum, wiredrawing processing, double shielding, effectively prevent electromagnetic radiation; And the silk screen components logo, let the installation technology personnel can clear understanding of product signal flow, convenient engineering commissioning;
9, the shell adopts new diecasted al-alloy shell and special waterproof seals, spray paint grain import hammer handle, heat dissipation, shielding, waterproof properties is admirable, facilitate field installation installed, particularly suitable for large and medium-sized Internet use.
