HFC 45-862MHz 4 Outputs Outdoor Bidirectional CATV Optical Receiver with AGC Control
Main difference between 9924 and the normal receiver
The receivers in the current market have the following problems:
Without bi-directional function
Frequency division is not changeable
Forward bandwidth cannot be widened
9924 is designed with the purpose of solving these problems, as a HFC bi-directional communication platform, all the components are plug-in type, it can be configured and upgraded flexibly according to the development of network.
Main function and features of 9924
Aluminum-casting housing, surface passivation, waterproof, heat-dispersing, electric conduction, antisepticising.
Flexible: (configurable, upgradeable)
HFC bi-directional communication platform, all the components are plug-in type; it can be configured and upgraded flexibly according to the development of network.
Function is configurable:
Frequency division is changeable:
Duplex filter, adopting mini plug-in component, a few kinds of filters are optional. Users can change uni-directional into bi-directional, low frequency division into high frequency division by filter.
In uni-directional network, choose 9940208/0 (47-862MHz).
In bi-directional network, choose:
9940207/0 (5-35/47-750MHz) (keep 1CH)
9940207 (5-42/53-750MHz) (no keep 1CH)
9940208 (5-65/87-860MHz) (high division)
Bandwidth can be widened:
9924 is designed as 1GHz passive platform, both the forward splitter and distributors are plug-in structure, with the development of integrated circuit technology, user can change the amplifier module to change 550MHz into 750MHz, 751MHz into 860MHz (or higher).
With perfect operating select display and test port.
Each RF output level has -30dB test port.
Each RF return input level has -30dB test port.
Forward receiving, with 10V/mW optic power detect, <-8dBm power lacking alarm.
Return path transmitter module, with 10V/mW power and 0.01V/mA bias current, <0.5 dBm power lacking alarm, -20dB RF input level test port.
Convenient to install and adjust:
Each RF output level, slope can be adjusted separately.
Each RF return input level can be adjusted separately.
Input of Return path transmitter module can be adjusted separately.
