Product Application

CiTRANS610A is the next-generation miniaturized optical transport device for packet transport based on MPLS-TP.

Brief introduction of device

CiTRANS610A is the next-generation miniaturized optical transport device for packet transport based on MPLS-TP. The device has a maximum switching capacity of 6G, provides interfaces such as GE, FE, E1, clock and time synchronization. It is located in the remote access layer of packet transport network, which can meet the demand of increasing IP services for bandwidth and enable flexible scheduling of bandwidth resources.

CiTRANS610A has the following features: 

  • Packet transport technology is used to meet operators' increasing demands for bandwidth and flexible bandwidth scheduling of the transport network

  • PWE3 technology is adopted to realize connection-oriented service carrying

CiTRANS610A device has two models: CiTRANS610A-8A (AC type) and CiTRANS610A-8D (DC type). The external view of the device is shown in Figure 1-1 and Figure 1-2.

Network Application

CiTRANS 610A is located in the far-end access layer of the packet transport network. It converges services at the edge access layer. 

The typical networking of the CiTRANS 610A is shown in Figure 1-3.
