CiTRANS 690 series is a solution introduced to cope with the development trend of carrier network packet, large bandwidth and integrated service. It realizes the integration of packet function and optical function in any proportion by adopting the unified cell exchange platform. CiTRANS 690 series covers convergence, core, trunk and other application scenarios, with a maximum exchange capacity of 12.8t, which is a new generation of high-end PTN products.

CiTRANS 690 series consists of 3 devices, CiTRANS 690 U10, CiTRANS 690 U20 and CiTRANS 690 U30, which can support 2.56t / 7.68t / 12.8t exchange capacity, respectively, and can realize comprehensive access to data services such as 100GE, 40GE, 10GE, GE, stm-1, etc. It can also position the core convergence of mobile PTN hosted network, PTN+OTN device iteration, trunk high-capacity business scheduling and other application scenarios. To meet the requirements of LTE wireless service centralized scheduling and integrated service unified load.
