A dedicated line service processing board-P222&P422 OTU Board
The transmission requirements for optical transmission dedicated line services mainly revolve around core indicators such as bandwidth, latency, reliability, security and stability. Besides commercial high-capacity dedicated lines, we have also launched small-capacity dedicated line service processing boards--P222 &P422 OTU board.
1. Support hot-swappable and FE~OTU2e service type
2. Support line-side online delay measurement at the ODU layer
3. Support Latency Measurement & Port Loopback
4. On-board 1+1 protection
5. Alarm and Performance Monitoring
Under the demand for high-speed and large-capacity services, the demand for low-rate dedicated line services is not widely utilized. However, dedicated line services, as a common requirement, cannot be ignored. This type of board precisely meets the security of the physical layer, exclusively utilizes the optical path, supports E2E QoS strategies, and uses OTDR cable detection to control the annual failure rate of the optical fiber link. It is the optimal choice for low-rate dedicated line services.
