Product information "VDL-001 Fiber Optic Delay Line"

840-1650 nm; Delay Range 0-1,200 ps; RL 50 dB; Fiber Type SMF-28, HI780, HI1060, PM Panda; IL 1.0, 1.5 dB; PDL 0.1 dB

The General Photonics VDL-001 module is a manually controlled variable fiber optic optical delay line. Multiple versions are available with path length of up to 1,200 ps. A low insertion loss and low variation of insertion loss is critical for most applications, and the VDL-001 has less than ±1 dB variation even up to 1,200 ps.

The delay line is packaged in a small aluminum box to prevent dust or noxious vapors from contaminating the optical path. The compact, rugged design makes the VDL-001 device ideal for integration in network equipment, test instruments, and optical coherence tomography (OCT) systems for precision optical path length or timing alignment.
