Delaylines

The VDL-002 is a miniaturized variable optical delay line designed specifically for OEM applications. With a delay range of up to 250 ps, this device is a superior replacement for the variable RF phase shifters inadequately adapted from the RF/wireless field for fiber optic communications.

General Photonics Manual Variable Optical Delay Line VDL-001 generates optical delays up to 600 ps (~18 cm).

Winding a large fiber spool is easy, but making compact, low loss fiber coils requires attention, precision, and skill.

Generating programmable time delay from nanoseconds to milliseconds is important for various applications ranging from data center testing to wireless communications to radar, optical communications, and measurement systems.

A suite of advanced polarization test instruments specially designed for testing the quality of fiber coils ensures the consistent production of high performance coils. GPCs' PM coils can be wound with different winding patterns such as quadrupole, octupole, or other types to minimize the Shupe effect, which degrades the performance of a fiber gyro under temperature-varying conditions.

General Photonics’ motorized variable optical delay line provides low cost, precision optical path length adjustment and delay scanning functionality. This addition to the MDL product line is specifically designed for OEM applications that require continuous scanning capability and a small footprint.

GPCs' motorized variable optical delay line provides precision optical path length adjustment of up to 560 ps, single-pass. Driven by a DC motor with an integrated encoder, the MDL-002 has a resolution of less than 0.3μm (1 fs).
