Summarization
With the supernormal development of Internet, service flow loading on network have been changing, data service is exceeding phoneme service bit by bit and becoming the dominant service flow. Traditional technology of building Metropolitan Area Network facing to phoneme can’t satisfy the new service require; RPR—Resilient Packet Ring possesses of advanced technology、superior price relations provide a nice solution of multi-operation convey.
As a kind of new product, RPR is possess of two dominant characteristic: 1) SDH monopolize: support ring technology efficiently and renew from severing fiber and lost losing link. 2) characteristic of Ethernet : high data efficiency、simply and low cost.
Standalone RPR—OPTurbo 3M/3C is exploited independently by Shenzhen MQ technologies industrial CO, LTD, dominant characteristic is:
1. RPR control chip die is designed independently;
2. Excellent impartial arithmetic can converge more smoothly when network is congesting and the accessing to bandwidth of ring crunodes is more impartial. At the same time, in order to ensure the QoS of service convey, it sets up CoS queue basing on IEEE802.17 while cutover control.
3. OPTurbo achieve IPS with hardware mechanism whose speed is 2 times as quick as one achieving IPS with software mechanism, so, it can reduce the loss of packet.
4. IPS of OPTurbo uses unusual edge WRAP more than center WRAP while achieving WRAP, therefore, it reduces route fluctuation and saves the invested capital for clients.
5. OPTurbo with speed mini-trim technology solve the jitter problem efficiently when command is conveyed.
6. OPTurbo can provide 32 tapes of E1 link for user with TDMoP technology and ensure the QoS of conveying phoneme service, moreover, it can connect directly with network equipment and switchboard which is a excellent platform for conveying phoneme and data.
Thanks to the characteristic upwards, bandwidth utility of MQT OPTurbo can increase 2—6 times when conveying data service. At one time, it’s IPS and QoS mechanism can also ensure the quality of conveying phoneme and data, making OPTurbo become one of optical Metropolitan Area Network solution supporting multi- operation.

MQT’s RPR optical Multi-Service Provisioning Platforms deliver a new level of reliability and performance to Metropolitan Area Network (MAN) service providers. RPR provides full support for legacy voice via TDM circuit services, while delivering new differentiated Ethernet, IP, and video services in a powerful yet efficient Multi-Service Provisioning Platform. The OPTurbo 3 M-Series is a NEBS-compliant, fully redundant carrier-class platform for deployment of services in medium- to high-density locations. The OPTurbo 3 M-Series achieves superior cost performance and functionality by integrating MPLS and Resilient Packet Ring (RPR, based on the emerging IEEE 802.17 standard) technologies into the platform. Targeted for central offices, cable TV headends, or co-location facilities, the 3 M-Series can be deployed in linear, mesh and ring topologies, providing service restoration from network outages in less than 50 milliseconds. The OPTurbo 3 M-Series uniquely addresses service providers’ requirements by eliminating network complexity, simplifying management, scaling capacity, and reducing operational and equipment costs.
Metro Ethernet Transport
Optimized for IP/Ethernet transport, the OPTurbo 3 M-Series provides full Layer2 support for transport, aggregation, and switching/grooming. Aggregation of multiple Ethernet services via Gigabit Ethernet interfaces provides carriers with efficient, high-bandwidth LAN/edge to MAN/core interconnect services. Flexible provisioning enables aggregated fractional Ethernet services delivered in private line or routed applications.
MQT Management System
MQT Management System is a scalable software suite to manage OPTurbo networks. It provides utilities for both network and system management. An intuitive graphical user interface facilitates administrative tasks in a simple and efficient manner. Integrated management functions include monitoring, event notification, service provisioning and system configuration for all OPTurbo products.
