Specifications
Outdoor DOCSIS3.0 CMTS , added more RF port in order to connect current optical equipment.It is Chassis cooling mode, no fan rain-proof design, mute operation. The data port can connect upward to Ethernet and EPON. As to RF port, there are 4 TV IN for connecting TV signals from the optical receiver while other 4 RF OUT for connecting coaxial cable network.
The Outdoor CMTS forward lead the data signal and tv signal mixture from the machine room to optical node, narrowed the upstream funnel and reduced the noise interference accordingly. It can rapidly cover and connect all users without reconstructing original optical network structure.

4. Typical Application
1) HFC+Ethernet Application
2) HFC+EPON Application
5. Several Connection Ways of Outdoor CMTS on Optical Node
1) Type Ⅰ
Independent DS/US Ports
This mode is suitable for having optical receiver(or the light station) of reserving descending input port and uplink output port.
Advantage: the least cable change, the minimum cost, no affection on output level.
Disadvantage: for the requirements of the optical receiver or the light station.
2) Type Ⅱ
Combined 4/2 Output Ports Type
It’s suitable to retain the original optical receiver, but there is no reserving upstream and downstream port.
Advantage: retain the original optical receiver, but do not waste existing resources.
Disadvantage: the cable change a lot, so that bring the insertion loss of 1-4dB for output level.
3) Type Ⅲ
4 Input & 4 OutputPorts
Smile the type Ⅱ, but the cable connection is simpler, more intuitive, less change.
