MEMS Variable Optical Attenuators: Single and Multi-Channel

Name: MEMS Variable Optical Attenuators: Single and Multi-Channel
Brand: OZ Optics
Availability: InStock

Description

The MEMS-based variable optical attenuators (VOAs) offered by OZ Optics are fast, low-cost, and available as single units or arrays. They feature independent continuous attenuation control for each channel, low insertion loss, high dynamic range, and stable and repeatable open-loop operation.

The attenuation is controlled by an analog DC voltage input signal, and they are available with either single-mode or polarization-maintaining (PM) fibers. These VOAs are ideal for signal power management, power balancing, gain equalization, and channel balancing in optical networks.

Frequently Asked Questions

What is a MEMS-based variable optical attenuator (VOA)?

A MEMS-based variable optical attenuator (VOA) is a device that can control the amount of light passing through an optical fiber by using a micro-electromechanical system (MEMS) to adjust the attenuation of the signal.

What are the features of OZ Optics' MEMS-based VOAs?

OZ Optics' MEMS-based VOAs are Telcordia GR-1209 and GR-1221 qualified, small in size and low cost, available in single channel and 4 & 8 channel arrays, and have independent continuous attenuation control for each channel. They also have low insertion loss, high dynamic range, and stable and repeatable open-loop operation.

What are the applications of OZ Optics' MEMS-based VOAs?

OZ Optics' MEMS-based VOAs are ideal for signal power management, power balancing, gain equalization, and channel balancing in optical networks. They can also be used for dynamic optical power control and channel equalization in add/drop multiplexers, power balancing before modulation and multiplexing, active gain equalization in DWDM systems, and channel balancing for optimizing transmission performance in long-haul and metro networks.

What is the difference between single-mode and polarization-maintaining (PM) fiber options?

Single-mode fiber is a type of optical fiber that allows only one mode of light to propagate through it, while PM fiber is a type of optical fiber that maintains the polarization of the light signal as it travels through the fiber. The choice between single-mode and PM fiber options depends on the specific application requirements.

What is the voltage input signal required to control the attenuation of OZ Optics' MEMS-based VOAs?

The attenuation of OZ Optics' MEMS-based VOAs is controlled by an analog DC voltage input signal. The voltage input signal can be either low voltage (6.5 V) or high voltage (18 V), depending on the specific application requirements.
