A high-speed electronic switch type optical cable protector

Abstract

The invention discloses a high-speed electronic switch type optical cable protector. The high-speed electronic switch type optical cable protector is applied to optical cable terminal equipment and arranged between main optical cable terminal equipment and standby optical cable terminal equipment, and conducts signal transmission and control with a peripheral PC through a human-computer interface. The high-speed electronic switch type optical cable protector is characterized by comprising a first light to electricity conversion unit, a second light to electricity conversion unit, a high-speed signal cross switching unit, a 3R amplification unit, an equipment monitoring unit, an electricity to light conversion unit, a passive light splitting unit and a power unit. Under the condition that light paths of optical cables are cut off due to uncontrollable external force or other factors, optical cable lines which are not broken off are automatically switched to, light signals can be transmitted without loss, and safe operation of optical cable communication is guaranteed.

Description

technical field [0001] The invention relates to line protection in the field of optical fiber cable communication, in particular to a high-speed electronic switch type optical cable protector. Background technique [0002] Due to irresistible external force or man-made damage to the optical cable equipment currently in operation, the optical cable communication is interrupted, which seriously affects the safe operation of the optical communication network. [0003] In the prior art, the optical path protector based on the mechanical optical switch is used to protect the optical communication, but because the optical path protector of the mechanical optical switch adopts the mechanical optical switch, the connection loss will inevitably be caused at the mechanical connection. And the mechanical size cannot be completely consistent, resulting in an optical signal with at least 3-5dbm insertion loss caused by light splitting, the insertion loss is large, and this loss may also ...

[0002] Due to irresistible external force or man-made damage to the optical cable equipment currently in operation, the optical cable communication is interrupted, which seriously affects the safe operation of the optical communication network.

[0003] In the prior art, the optical path protector based on the mechanical optical switch is used to protect the optical communication, but because the optical path protector of the mechanical optical switch adopts the mechanical optical switch, the connection loss will inevitably be caused at the mechanical connection. And the incomplete consistency of mechanical dimensions, resulting in at least 3-5dbm insertion loss caused by optical signal splitting, the insertion loss is large, and this loss may also cause the original optical cable transmission to be interrupted; the relay used in the mechanical optical switch It needs current drive to generate magnetic force to control the switch to operate, and all optical signals will inevitably lose information, so the optical signal switching time is long, the signal loss time is long, and it cannot adapt to various optical cable maintenance site conditions
