VDL-002 Fiber Optic Delay Line

Product information "VDL-002 Fiber Optic Delay Line"

840-1650 nm; Delay Range 0-250 ps; RL 55 dB; Fiber Type SMF-28, HI780, HI1060, PM Panda; IL 1.0 dB; PDL 0.1 dB

General Photonics’ VDL-002 variable fiber optic delay line module is approximately half the volume of the VDL-001 unit . Path length of the VDL-002 delay line is up to 250 ps, compared to the maximum delay of 1,200 ps in the larger VDL-001.

A single VDL-002 device can be used for any data rate, simplifying inventory management. With a footprint of only 78 × 22 × 15 mm for a delay range of 100 ps, the device can be conveniently integrated into network modules, test instruments and OCT equipment for precision optical path length control or timing alignment.

An internal mirror can be installed to cause light to double pass the device, doubling the delay range. The patent-pending design makes hermetically sealed packaging possible and enables Telcordia qualification when required.

Finally, a locking mechanism is provided for locking the delay at a permanent position. The VDL-002 generally comes with single mode (SM) or polarization maintaining (PM) fiber pigtails per customer requirement.
