2 Safety Information

WARNING

Do not install or terminate fibers while a light source is active. Care

must be taken to ensure that the instrument has been turned OFF

before inspecting the end face(s) of the instrument, or any optical

patch cords connected to this instrument. Never look directly into a live

fiber and ensure that your eyes are protected at all times.

The use of controls, adjustments and procedures other than those

specified herein may result in exposure to hazardous situations or

impair the protection provided by this unit.

CAUTION

The VOABlade expansion modules are sensitive to electrostatic

discharge (ESD). Please be sure to store the modules that are not

installed in protective electrostatic packaging.

IMPORTANT

For electromagnetic compatibility, this instrument is a Class A product. It is

intended for use in an industrial environment. There may be potential

difficulties in ensuring electromagnetic compatibility in other environments,

due to conducted as well as radiated disturbances.

3 Introducing the VOABlade - Modular Variable Optical Attenuator

Coherent Solutions’MTP1000 & VOABlade is a reliable, fast and high density attenuation solution for research

and continuous-production environments. The attenuators are installed as modules with 2 or 4 attenuators.

Each module has an integrated power meter for precise output power control, even with fluctuating input.

With up to 9 VOABlades in a single unit, you have up to 36 individual attenuators - which can be controlled

individually or in sync through one, intuitive software application.

The modular chassis design of the MTP1000, with nine (9) expansion slots, can hold up to thirty six (36)

variable optical attenuators providing great flexibility to manage the number of attenuators to meet changing

laboratory demands.

All MTP1000 mainframes connected to the

network can be managed remotely from a

single client using the simple and intuitive

‘Test Instrument Manager’software

interface.

Alternatively, VISA programming

environments such as MATLAB can also be

implemented to integrate with existing test

software or data collection procedures.
