Product Positioning

CiTRANS 650 is a compact POTN product launched to meet various flexible transport needs of access layer. It is compatible with MPLS-TP technology and OTN technology, and is targeted at the access or edge aggregation node of MAN to meet the full-service access requirements of operators.

Product Profile

CiTRANS 650 uses a unified VC/ODUK/Packet switching platform to provide customers with Ethernet, TDM, OTN, SAN, CPRI, video services, and other access services. The product supports multi-device stacking to realize the expansion of access services and channel number. At the same time, the product has perfect QoS mechanism, reliable service processing and operation and maintenance capabilities.

CITRANS 650 series products include CITRANS 650U2 DC, CITRANS 650U2 AC, CITRANS 650U3 and CITRANS 650U5. The external views of the four devices are shown in Table 1-1.

CiTRANS 650 series products support the expansion of access services and channel services through extended subframes. Devices supporting the extended subframe function include CiTRANS PRO and U3 WDM function subframe. The external view of the extended subframe is as shown in Table 1-2.

Network Application

CiTRANS 650 is mainly used in the access or edge aggregation node of MAN, as a multi-service convergence carrying platform, Aggregate services into the core/backbone network. The application of CiTRANS 650 in the network is shown in the following figure.
