Product Overview
Huawei SmartAX MA5633 distributed converged cable access platform (D-CCAP) head end device (MA5633 for short) is a
full-service, digital cable network device designed for Fiber Deep migration. Installed at the edge of an HFC network, the
MA5633 delivers a Gigabit bandwidth to a single group of users at a lower cost than FTTH. With the built-in EQAM or optical
receiver, the MA5633 is fully backward compatible to existing QAM-based services. A Huawei OLT located at the head end
aggregates up to hundreds of distributed MA5633s and provides space, power, and cooling efficiencies required for a large-
scale transition toward Fiber Deep. Positioned to support the SDN framework, the D-CCAP further evolves HFC.
Product Highlights
High Bandwidth
Supports a maximum downstream rate of 1600 Mbit/s in QAM 256 mode and a
maximum upstream rate of 320 Mbit/s in QAM 256 mode.
High Integration
Built-in optical receiver or transceiver
Significantly simplifies installation and cable connections because only
one chassis needs to be installed.
Reduces installation space, resolving issues caused by space
limitations on installing a ground-based network box.
Supports remote management and alarm generation for the optical
receiver or transceiver.
Built-in wavelength division multiplexing (WDM)
The built-in WDM applies in newly deployed networks where feeder fibers
are insufficient, which reduces optical fiber investments and fiber routing.
Built-in edge quadrature amplitude modulation (EQAM)
The built-in EQAM applies in newly deployed networks or the networks
requiring reconstruction in both downstream and upstream directions. On
these networks, no external EQAM needs to be purchased or installed in
a hub equipment room, which reduces investments and maintenance
costs and simplifies hub equipment room deployment.
Comprehensive QoS Measures
Supports traffic burst, which transiently improves user bandwidths using
idle bandwidth resources without changing QoS parameter settings. This
feature shortens user waiting time and enhances user experience.
Supports the configuration of downstream and upstream committed
information rates (CIRs), preferentially ensuring the bandwidths of VIP
users.
Converged Services
Supports heterogeneous access and shared platform for provisioning
cable and fiber to the home (FTTH) services, which simplifies coordinate
network construction.
Supports L2VPN business services over DOCSIS (BSoD).
Dot1Q-based and Dot1ad-based L2VPN services
MPLS-based L2VPN service (An OLT model MA5800 is required.)
Provides an integrated solution for video and data services using a built-in
EQAM, which simplifies network deployment.
Dual-channel 60 V AC power supply
Ensue that the device functions normally when one-channel 60 V AC power
supply fails.
Complete Maintenance and Management
Supports centralized management. In this mode, the MA5633 is plug-and-
play and regarded as a service board of the OLT. The functions of the
combined OLT and MA5633 are the same as those of centralized CCAPs.
All maintenance operations are performed on the OLT. The OLT supports
remote configuration, upgrades, and O&M for the MA5633. This allows
simple and efficient maintenance and management.
Supports Internet Protocol Detail Record (IPDR), an efficient data statistics
and reporting mechanism used for accounting, fault locating, and network
running status monitoring purposes to meet routine O&M requirements.
Supports upstream spectrum scanning. Upstream cable channels are
prone to interference from external noises, which adversely affect CMs
and user services.
In spectrum planning, this function enables the MA5633 to obtain noise
distribution on upstream channels so that the MA5633 can configure
services in the frequency bands with weakest noises, minimizing noise
interference on services.
In network O&M, this function can be used to detect line noises to
assist fault diagnosis.
This function supports the spectrum scanning file storage for follow-up
manual analysis.
The U2000 supports upstream spectrum scanning. Spectrum range 0–
81.92 MHz supports quiet noise scanning. The sampling is performed
at an interval of 1s and step of 20 kHz. The collected data is displayed
at a delay of 1s.
Controls RF port status. The MA5633 supports two-status configuration.
The two statuses are enable and disable. The two statuses work with the
upstream spectrum scanning function provided by the U2000. In this way,
the MA5633 can rapidly identify an RF line where a noise source locates,
thereby improving troubleshooting efficiency.
Supports proactive network maintenance (PNM): Before a network fault
adversely affects user services, the fault diagnosis system connected to
the MA5633 detects this fault based on the analysis on the pre-
equalization coefficients obtained between CMs and the MA5633. This
function maximally decreases faults, thereby reducing network O&M costs
and improving carriers' service level agreement (SLA).
Supports maintenance using mobile Apps. Using mobile Apps, CMCs,
cables, and CMs can be maintained, and the following information can be
queried: CMC statuses and locations, downstream and upstream channel
parameters of cables, MAC and IP addresses of CMs, and working
channels of CMs.
Reliability Design
The MA5633 features wide temperature range, low power consumption and
noise, and can be used in extreme weather conditions.
It complies with IP65 when its 60 V AC voltage transmitted over the cable, and
complies with IP20 when a port is used for 220 V AC power supply and 60 V
AC power supply.
The shell of the MA5633 is made of die casting aluminum alloy, which enables
the bottom layer of the shell to use cooling grooves to implement passive
cooling.
The surge protection level of the MA5633 is as follows: 6 kV in both common
and differentiated modes for the AC power port; 10 kA in common mode and 3
kA in differentiated mode for RF ports.

built-in optical receiver scenario and GE upstream transmission is used as an example in embedded optical receiver and embedded WDM scenarios.
Typical D-CCAP networking of the MA5633
D-CCAP Network Structure
A distributed converged cable access platform (D-CCAP) network consists of an optical line terminal (OLT), coaxial media converters (CMCs), and a U2000
network management system, complying with the remote MACPHY architecture requirements specified by CableLabs DCA (Data-Over-Cable Service Interface
Specifications).
OLT: an aggregation device (CMC controller) that terminates the PON protocol and locates in a central office (CO). The OLT manages CMCs in a centralized
manner.
CMC: forwards data signals at Layer 2 between the upper-layer network and the HFC network.
U2000: virtually manages and maintains NEs and services in the D-CCAP network.

Module
Function
Power
module
Converts the input 220 V AC or 60 V AC voltage to the 24 V or 12 V DC voltage required by each module.
WDM
module
The WDM combiner located in the branch equipment room combines data signals with CATV signals for transmission over one feeder fiber and
the WDM module built in the MA5633 on an FN separates data signals from CATV signals.
In the downstream direction, the WDM module sends the CATV signals to the optical receiver or transceiver module and the data signals
through PON or GE optical module to the CMC module for forwarding.
In the upstream direction, the WDM module sends the data signals to the upper-layer device.
Optical
receiver
The functions of an optical receiver module are as follows:
Optical receiver module: converts optical signals to RF signals. An optical receiver module consists of optical receiving components, an RF
power amplifier, a gain regulator, and an EQ regulator.
The RF signals after O/E conversion are sent to the RF module.
CMC
module
Converts data between the upper-layer network and the HFC network.
In the downstream direction, the CMC module modulates data signals to RF signals and sends the RF signals to the RF module.
In the upstream direction, the CMC module demodulates the RF signals sent by the RF module to data signals for data conversion.
RF module
In the downstream direction, the RF module uses a combiner to combine downstream signals with CATV signals. The combined signals are
high-frequency signals. These signals pass through a high-pass/low-pass filter to CMs connected to RF ports.
In the upstream direction, upstream signals are low-frequency signals. They pass through RF ports and a high-pass/low-pass filter over
upstream channels to the RF module for modulation.
EQAM
Multiplexes and modulates IP-based media data to RF signals and sends these signals over downstream channels to the RF module and then to
STBs.
