Three-in-one chassis CMTS
Overview
This is a three-in-one chassis CMTS products containing optical receiver module,ONU module and
the CDOCSIS module. It is deployed at the optical nodes for the integrated solutions. The CDOCSIS
module is strictly according to its standard. With a high degree of standardization, it effectively fulfills
the requirements of the existingand future CDOCSIS technical standards . The optical receiver module
and the ONU module adopt matured ones and go for commercial use stably and reliably over five years.
The three-in-one modules are mutually independent and field replaceable . And the maintenance
is also very convenient.
The product provides 16 downstream channels, bandwidth to 800Mbps; 4 upstream channels ,
bandwidth to 160Mbps,fulfilling the broadband accessing of 960Mbps. It can support 511 Cable Modems
online simultaneously, fully compatible with the DOCSIS2.0,3.0 Cable Modem.
Key Features
