| Description
OPR-1285D is a latest version of bi-directional optical fiber CTAV terminal equipments. It contains an optical receiver and a reverse channel transmitter. It adopts low noise high sensibility PIN diode as optic-electric converter, GaAs amplifier module to amplify, With high performance, reliability, low cost and compact design, it is especially suitable for HFC CATV bi-directional networks.
Features
(1) Excellent linearity, flatness and low return loss
(2) Compact construction, low power consumption
(3) WDM option to achieve single fiber bi-directional transmission
(4) Single out (75Ω Impedance )
(5) Amplifying circuit adopts GaAS material
