Hybrid Fiber Coax (HFC) - the ultimate
solution for cable network operators
Based on our long and extensive experience in the field of cable
TV networks, we are able to offer special solutions for a cost
efficient installation of flexible and modular HFC networks which
can be expanded as needed at any time.
Flexible configuration
A flexible configuration of the network is possible because all
major functionalities are modular in nature and can be added to
the system configuration as needed. Insertion of certain
additional modules and thereby incrementing system
performance is possible at any time.
Extension of bandwidth
Our DWDM and CWDM solutions allow establishment of
bandwidth as the need arises and subsequent upgrading is no
problem. Single signals can be added or filtered with optical
add-/drop multiplexers.
Network management
All BKtel components are designed for configuration and
monitoring by either SNMP or web browser. BKtel's element
management system CABLEwatch provides special features
which make the operation of our equipment even more efficient.
DOCSIS 3.1
The new standard for data transmission in HFC networks,
DOCSIS in the latest version 3.1, provides the basis for efficient
data transmission at speeds that can otherwise only be
achieved by a fibre-to-the-home network. BKtel already has the
complete product family for optical transmission available
according to the new standard.

Distributed access architecture (DAA) enables the evolution of
HFC networks by digitizing the optical transmission and
decentralizing headend functionality. The new converged
interconnect network (CIN) replaces the analog optics with digital
optics while the analog fibernode is replaced with Remote PHY
or MACPHY. A massive increase in network capacity can be
realized with this new approach. Huber+Suhner Bktel offers a
comprehensive CIN solution and a roadmap to RPHY and
MACPHY products.
