Lightwaves2020 Variable Optical Attenuators

Lightwaves2020 Variable Optical Attenuators

Lightwaves2020's state-of-the-art Liquid Crystal based VOA products have recently added new family members in order to meet customers' versatile applications.
Lightwaves2020 is one of the few fibre optic component manufacturers to bring to market the benefits of using Liquid Crystal technology in VOA components. Our proprietary device structure and laser-welded packaging guarantees the simplified assembly with high alignment accuracy and reliability. There is no moving part during the adjustment process. Lightwaves2020's LC VOA offers many advantages including static charge resistance, continuous tuning, low PDL, high attenuation, low WDL and ripple, voltage controllability, and low power consumption. It is also capable of high power handling, the critical parameter for optical amplifier applications. Due to our LC VOA's innovative design and high manufacturing standards, it is extremely stable and insensitive to vibrations of nearly all frequencies and mechanical shock.

Agiltron MEMS VOAs

Agiltron MEMS VOAs

Single-crystal silicon is an ideal material for miniature mechanical devices. Silicon is inexpensive and has virtually no hysteresis and hence almost no energy dissipation, as well as little fatigue to ensure service lifetimes over trillions of flexing cycles without breaking. The lightweight and thin format enables optic devices with improved vibration resistance and compactness. Based on proprietary Si micro-machined VOA chips, Agiltron’s MEMS Electrical Fibre Optic Attenuator family features industrial leading performance in low insertion loss, low WDL/PDL, and low cost. The MM VOAs are conveniently controllable by directly applying a voltage. The MM VOA series is in full compliance with the Telcordia 1209 and 1221 reliability standards. We offer a wide range of configurations covering singel mode, multi-mode, polarisation maintain, single channel, multi-channels, and integrated tap versions.

Agiltron NanoSpeed Variable Optical Attenuators & Splitters

Agiltron NanoSpeed Variable Optical Attenuators & Splitters

The NanoSpeed™ High Speed Variable Optic Attenuator family features ultra-fast sub-millisecond response, non-mechanical high reliability, and a wide operating temperature range from -50°C to +90°C. These VOAs are designed to meet the most mission-critical high speed optical switching applications. The patent pending NanoSpeed™ VOA is non-mechanical, controlled by an electrical filed inside an inorganic optical crystal to facilitate fast light intensity control. With a compensation technique, the out-put light intensity is highly stable against environmental variations. Having an integrated electronic driver, the switch is conveniently controllable by a low voltage with speed up to 150KHz. The high speed VOA can also be operated at a fixed 5MHz with full attenuation. With partial attenuation, the high speed VOA can be modulated up to 500KHz.

High Precision Electronically Controlled Optical Attenuator

High Precision Electronically Controlled Optical Attenuator

The High Precision Series VOA is based on a micro-electro-mechanical system (MEMS) device platform driven by a mini-motor integrated with an optical position sensor. It uniquely offers advantageous performances that are unmatched in the industry. It features ultra-broadband from 200 to 2500nm, ultra-low insertion loss of less than 0.2dB, ultra-high setting precision, high optical power handling, and latching function. Once, the VOA attenuation value is set, it will latch to and remain at the value regardless of the environment variations and the loss of electrical power. It is available with all types of fibres having a 125 micron outer diameter.
The VOA is driven by a attached PCB having USB or RS232 computer interfaces with GUI software. A USB connection will provide sufficient power for the device. A wall-mount 12V DC supply is provided for RS232 function.
