Economical outdoor super low power optical receiver

Detailed

Introduction

 

E-8721 series outdoor super low power optical receiver is one extraordinary product that is manufactured by our company by selecting Japanese FUJITSU highly sensitive optic radio-detector, and renovated through further technological improvement on basis of our series optical receiver. Equipped with FUJITSU highly sensitive optic radio-detector for internal integrated GaAs low noise pre-positioned amplifying circuit, it ensures normal receiving of signal even if optic power receiving range is as low as -9dBm, and enables easy restoration of normal operation of those optic nodes that could not operate normally due to lower optic power. It is the choice of high performance-price ratio product suitable for medium and small sized CATV network.

 

Features

 

l         Japanese FUJITSU super highly sensitive optic radio-detector as optic receiving part; original PHILIPS or MOTOROLA low noise push-pull amplifier module as RF amplifying circuit at front position, and PHILIPS or MOTOROLA diplex amplifier module as output. (GaAs amplifier module is available according to customer’s requirement.)

l         With built-in inserted (reserve) return-path reverse transmission optic emitting assembly, it is easy to open return path.

l         Inserted diplex filter, inserted fixed equalizer, fixed attenuator, inserted output tap, 8-level optic power indication, are scientifically and reasonably laid out at test port, allowing easier engineering debugging.

l         Al casting waterproof casing, highly reliable switching power supply, rigorous anti-thunder system, ensure the product’s constant stable operation under outdoor abominable condition.

l         Able to operate normally under -9dBm super low optic power condition, with high performance-price ratio, suitable for medium and small sized CATV network.
