Title: Tunable optical add/drop device and method
Inventor: LIOU KANG-YIH
IPC: H04B10/43
Filed: 2001-02-14
Abstract: PROBLEM TO BE SOLVED: To realize reduction in data loss and improvement in bandwidth efficiency when tuning by incorporating a hitless tunable optical filter in an optical add/drop device. SOLUTION: The hitless wavelength-tunable optical filter is provided with a broadband reflective region and a tunable filter region, and a reflective surface and a filter surface are positioned adjacent to each other. Hitless tuning of the device is accomplished by changing (moving) a point from which an optical beam is made incident on the filter region along a constant wavelength channel track whenever the optical beam strikes the filter region of the device. Realignment (moving) to a position related to a new wavelength channel track is performed in a state where the optical beam strikes the broadband reflective region.  First, the optical beam is moved to a position corresponding to the new wavelength to be added/dropped on the filter region (in the broadband reflective region), subsequently the optical beam is realigned (moved) along the new wavelength channel track within the filter region.

The vicinity of the pivotally supported section of the braking lever and the vicinity of the pivotally supported section of the braking piece are connected by respectively inserting spindles 25 and 26 in both end sections of a link 16. When the braking lever is rotate-operated, the spindle 24 of the braking lever and the spindles 25 and 26 are arranged on one straight line, and the braking lever is prevented from returning by further exceeding the state being arranged on the straight line.  Then, the pressing section is locked under a state wherein the pressing section is pressed to the tire 3 of a wheel 2. At the same time, a spring 17 which urges the braking lever in the returning direction is provided. Thus, the braking piece is towed by a remote control from the handle lever 9, and the pressing section is pressed to the tire. In this case, the braking lever is returned by the elasticity of the spring when the spindle 24, and the spindles 25 and 26 are arranged in one straight line by the control of the handle lever.
