integrated input tap
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.
