Attenuators
Voltage-Controlled Optical Attenuators (PDF, 0.13 MB)
The JDSU VCB Series of voltage-controlled optical attenuators is specifically designed for highly reliable optical power control in network applications. These devices are available with an input tap for optical monitoring purposes, eliminating the need for external tap couplers. They are Telcordia GR-1221 compliant, through the use of hermetic sealing technology, and feature latching capabilities. They show excellent optical performance over the C and L bands.
Each attenuator uses a stepper motor driven by an external IC driver to achieve fine attenuation resolution. The driver for the stepper motor is user-supplied to move the motor up or down in uniform step sizes. Latching operation is a standard feature; upon removal of the drive voltage, the most recent attenuation setting is retained.
JDSU attenuators withstand the diverse environmental conditions encountered in network applications. They ensure high reliability, particularly during long quiescent periods.
