Optical Reflectors

Fiber Optical Variable Reflector

The VRFL Series of Fiber Optical Variable Reflector is a single fiber device that reflection the input light backward with variable ratio between 100-0% by applying a control voltage. It is constructed using an electrostatic rotating mirror hermetically sealed with nitrogen, featuring high repeatability, low power consumption, and low cost. A voltage between 0-9V on the drive pin sets the optical attenuation. When power is removed, the VRFL returns to its default 100% reflection state. The device’s electrical character is capacitive without polarity. It can be mounted directly on printed circuit boards. The component is compliant with RoHS requirements and Telcordia standards GR1221 qualified. We provide customized designs and modular assemblies to meet control and integration applications.

Application context

Why this design is used

Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.

Laboratory optical integration

Fiber Optical Variable Reflector: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1260~1620, 980-1250, 770-1100, 620-850, 600-780, 488-635, 460-600, 850/1310, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, PM1550, PM980, PM780, PM850, PM630, PM460, MM 50/125, MM 62.5/125, SM450, SM460, SM600, SM630, 780HP, HI1060, PM1310) must match the connected components.

Use these checks to connect Fiber Optical Variable Reflector to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Optical interface and fiber: Fiber Type: SMF-28, PM1550, PM980, PM780, PM850, PM630, PM460, MM 50/125, MM 62.5/125, SM450, SM460, SM600, SM630, 780HP, HI1060, PM1310 · Fiber Cover: Bare fiber, 0.9mm tube, Special; Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength and loss budget: Wavelength: 1260~1620, 980-1250, 770-1100, 620-850, 600-780, 488-635, 460-600, 850/1310, Special; Check the Optical Reflectors passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
