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
