Problems solved by technology

[0011] Especially in large-scale networks, a variety of new equipment and old equipment are mixed, and various networking methods coexist. The reliability of traditional optical fiber communication nodes and repeaters and other equipment has already affected the work of local or entire communication networks. Stability and Security
[0012] The network is becoming more and more complex, and traditional communication node devices and repeaters will also fail due to emergencies, such as power outages, etc. This failure may cause irreparable damage to the chain network or ring network where it is located. Physical disconnection fault
like figure 1 As shown, when both the intermediate nodes of the master link and the slave link are powered off, the communication between master node A and master node B will be interrupted

Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] see figure 2 , first add the underlying physical unit for the optical fiber communication equipment, including the optical switch and the basic optical fiber communication channel, the optical switch can freely set the gating mode to 1×2 or 2×2 according to different gating modes, figure 2 Shown is 1×2 pattern. In order to achieve smooth gating, the optical switch needs to meet many pre-required parameter values, such as switching jitter, switching time, return loss, switching life, etc.

[0022] Then set the switch automatic switching threshold of the optical switch for the power detection unit. This threshold is a bidirectional trigger threshold, that is, when it is less than the threshold, the optical switch switches to the through state, and when it is greater than the threshold, the light switches to the non-through state.

[0023] see figure 2 As show...

Abstract

The invention belongs to the optical communication field and relates to an optical path direct connection method with power interruption. The optical path direct connection method for optical communication equipment with power interruption can increase light switches to traditional optical fiber communication nodes. Through reasonable configuration of a switching mode of the light switches, shielding failure nodes and the function of direct connecting upstream signals and downstream signals are achieved at the time of power interruption of network link and an equipment trouble of the fiber nodes. Due to the fact that the optical path direct connection method can more flexibly set the proper optical power threshold value, response speed can be fast, and therefore communication chain break of the entire link caused by the power interruption of individual equipment or a equipment trouble can be avoided effectively, and stability and safety of the network link can be greatly improved.

Description

[0001] technical field [0002] The invention relates to a method for connecting an optical path when an optical communication device is powered off. The optical path straight-through method adopts a power-down transmission protection method based on optical switch intelligent monitoring and automatic switching, which can effectively improve the self-recovery ability when the internal communication of the Ethernet fails, and can also ensure the normal transmission of internal data in the ring network when the network load is large. Fast self-healing after the internal link of the Ethernet is broken, ensuring the continuity of the data transmitted by the network communication link when the network is suddenly powered off or the optical fiber transmission equipment is powered off, reducing the ring network disconnection caused by power off, thereby The network signal is interrupted. [0003] Background technique [0004] At this stage, communication systems have a variety of...
