A sliding housing has an arc portion surrounding the insert pipe, a tightening block at each end, and a variable inner cross-section that changes with distance between the tightening blocks. An upper housing is tiltable relative to the sliding housing. A tilt plate is fixed to the upper housing, extends to the tightening block, and has an arc-shaped slot corresponding to a rotation distance of the tilt plate. A locking bolt passes through the arc-shaped slot of the tilt plate and through the tightening blocks. An operation lever is rotatably fitted on the locking bolt. A cam assembly variably applies a force to the tilt plates and the tightening blocks according to a rotation distance of the operation lever.

摘要： There are provided a method and system for monitoring an optical transmission line. The system for monitoring the optical transmission line includes: an OTDR (optical time-domain reflectometer) transmitting a monitoring light to an optical transmission line, measuring a reflected light or backscattered light to monitor the optical transmission line; an optical amplification unit amplifying the monitoring light transmitted on the optical transmission line by using a gain clamped optical amplifier; and a filter unit removing a component having a wavelength outside a wavelength band of the monitoring light from a backward ASE (amplified spontaneous emission) generated by the optical amplification unit. Accordingly, it is possible to extend an optical transmission line monitoring distance of the OTDR. As a result, it is possible to prevent deterioration of the performance of the OTDR because of the backward ASE.
