NOR1GT-4 CWDM

Query



        NOR1GT/4 CWDM type is a two ways optical station and the ideal platform for delivering video (digital or analog) as well as high-speed data services over advanced hybrid fiber/coax (HFC) network; this Optical Node combines the superior proven technologies of both the RF amplifier and optical components. Available with four high levels RF output ports. With its modular design of fiber receiver reverse fiber transmitter and RF amplifier electronics, the NOR1GT/4 can provide the full complement of functions required by advanced networks.


       Features

 Four high level output ports with Ga As power double amplifier module

 25 ampere current capacity (steady state) and 25 ampere surge survivability

 Surge Resistant Circuitry ensures gain stage protection without fuses or other nuisance failure-causing device.

●Two 40-90V AC high-efficacy switch mode power supplys

 Forward redundancy with two 1310/1550 nm optical receivers (optional)

 Standard fiber management tray provides fiber and connector storage for up 6 connector pairs.

●Four reverse transmitters according to four ports and xixed witch CWDM using only one pieces of fiber for up and down streams.

 Local test points and LED indicators on optical receivers, transmitters, and optical simplify installation and maintenance

 Optical status monitoring and control

 The NOR1GT/4 launch amplifier uses fixed-value plug-in accessories

 Forward output test point and Reverse input test point for each port on NOR1GT/4 launch amplifier allow optimum design and alignment
