Product Positioning

CiTRANS 690 series products are metro transport device for packet transport introduced by FiberHome Telecommunication, which are mainly used in metro aggregation layer to realize multi-service carrying by end-to-end networking with PTN of metro core layer and metro access layer, and can also be applied to metro core layer to realize flat networking according to service and networking requirements.

Product Profile

With the large-scale deployment of LTE network and the promotion of full-service development strategy, various emerging IP-based service applications have increasingly higher requirements for the bandwidth, scheduling flexibility and service quality of the carrying network.

CiTRANS 690 series products adopt unified cell switching, which is flexible in scheduling, and can realize unified transport of packet,

TDM and other services. The products include CiTRANS690U10, CiTRANS 690U20, CiTRANS 690 U30, providing solutions from low-end to high-end devices, and the product external view is shown in Figure 1-1, Figure 1-2 and Figure 1-3 respectively.

Network Application

CiTRANS 690 series products are mainly used in the aggregation layer and core layer of metro transport network, responsible for transport of packet service in the network, and aggregate the service to IP/MPLS backbone network.

The application of CiTRANS 690 series products in network is as shown in Figure 1-4
