摘要： A measurement system is a measurement system inspecting an optical transmission line configured by connecting a plurality of optical cables, each of which includes a plurality of optical fibers, wherein the optical transmission line includes a plurality of optical fiber lines configured by connecting the plurality of optical fibers in the plurality of optical cables, the measurement system including: a first measurement device configured to be disposed at a first end of the optical transmission line; and a second measurement device configured to be disposed at a second end of the optical transmission line, wherein the first measurement device and the second measurement device perform a first measurement to inspect whether the optical cable is misconnected, and a second measurement to inspect the plurality of optical fiber lines in a case where it is determined that there is no misconnection in the first measurement.

摘要： An optical fiber rack includes a rack part on which a plurality of termination units are located, a first optical fiber housing part in which extra length wiring parts of a plurality of first optical fibers are housed, a second optical fiber housing part in which an extra length wiring part of a second optical fiber connected with any of the plurality of termination units is housed, a partition plate partitioning the first optical fiber housing part from the second optical fiber housing part, and, a plurality of optical fiber guides attached to the partition plate and arranged in the vertical direction. The optical fiber guide comprises a first guide part housing the first optical fibers toward to the first optical fiber housing part, and a second guide part housing the second optical fiber passing through an opening provided in the partition plate.

摘要： A bracket for attaching an optical unit to a rack is provided. The bracket comprises a bracket body and a fastener. The bracket body has a first wall including a first face and a second face opposite to the first face, and a protrusion extending in a direction intersecting with the first wall from the second face against the first face. The bracket body is provided with a hole penetrating through the first wall from the first face to the second face. The fastener is arranged to pass through the hole on the first wall and is configured to be rotatable with respect to the first wall. The fastener has a first hook including a holding surface substantially parallel to the second face. The holding surface of the first hook faces the second face to define a first gap between the holding surface and the second face of the first wall at least when the fastener rotates from an initial position to a first locking position.

摘要： An optical source that implements a wavelength tunable laser diode (t-LD) and a Mach-Zehnder (MZ) modulator within a single package is disclosed. The optical source, which outputs a modulated signal beam and a local beam of a continuous wave (CW), accompanies a control circuit mounted on several circuit boards. Only one of the circuit boards is rigidly mounted on the housing of the optical source. Rest of the circuit boards is moderately fixed to the housing through the rigidly fixed circuit board to suppress stresses caused in the housing and the circuit boards when the optical source is rigidly installed in the host system.
