Powerful GPON / EPON integrated access capabilities

· EPON access capability

Ethernet as the carrier, using point to multi-point structure, passive optical fiber transmission. 1.25Gbit / s uplink and downlink symmetric rate, high-speed broadband, fully meet the bandwidth requirements of access network users.

Downlink uses the way for different users to encrypt the broadcast transmission to share the bandwidth, and uplink uses TDM (Time Division Multiplex) to share the bandwidth.

In this case,

The MA5680T series supports Dynamic Bandwidth Allocation (DBA) algorithm, which supports 64kbit / s control granularity and dynamically allocates the ONT bandwidth according to user requirements.

EPON system uses passive optical transmission technology, optical path separation using P2MP (Point to Multiple Point) approach to support the 1:64 split ratio.

Can achieve maximum access capacity of 20km.

Ranging technology using time ranging, automatic ranging, initial ranging methods.

 Products Imformation

• VoIP service

  After passing through the ONT, the VoIP packets reach the MA5680T. The MA5680T then transmits the packets to the NGN network, or to the PSTN network through an MG.

• Data service

  The PCs are connected to the MA5680T through the ONTs. The PCs are then connected to the IP network through the BRAS.

• Video service

  The video traffic is sent to the ONTs in the IPTV or cable television (CATV) mode.

  Video services in the IPTV and CATV modes are described as follows:

• IPTV

  In the IPTV mode, the video service is delivered over IP multicast traffic, supplying users with various programs.

  The MA5680T manages the multicast user rights and programs based on IGMP proxy and controllable multicast. After the users have passed the authentication of theMA5680T, the MA5680T transmits the IGMP protocol packets to the device at the convergence layer.

  The multicast server transmits the video traffic to the MA5680T through the backbone network and the convergence network. The MA5680T forwards the traffic to the user terminals based on the authentication results.

  At the user end, the STB terminates video signals, performs media conversion, and controls program switching.

• CATV

  Through the electrical-to-optical conversion, video streams are converted into downstream optical waves, and then superposed with downstream optical waves of the GPON in the wavelength division multiplexing (WDM) mode. The superposed waves are transmitted to the ONT in the downstream direction through an optical fiber. Then the ONT separates the video signals from the waves, and sends the signals to the TV. In this manner, the video service is implemented.
