Variable Optical Attenuator - Collimator Type

Collimator type variable optical attenuator (VOA) utilizes miniature collimator structures to achieve continuous, accurate and variable optical attenuation in a wide spectrum. It can achieve 0.6dB to 60dB attenuation with a precision of 0.1dB.

1310nm, 1550nm or dual-window products are available. Within each operating window, the VOA has +/-40nm working bandwidth.

VOA for 850nm or 1310nm multimode fiber (50/125 or 62.5/125um) is also available.

Features:

• Collimator based variable optical attenuator, compact size (26x18x8mm)
• Wide operation wavelength
• High precision
• Low excess loss
• Two adjustment types: by handle or by screwdriver

Applications:

• Optical communication system tests
• Optical passive component tests

Specifications:

Note: products for multimode fiber at 850nm or 1310nm are also available.

VOA adjustable by handle

VOA adjustable using screwdriver

Ordering Information:

VOA-C-a-b-c-d
a: Operating Wavelength, a=1310 for 1310nm, a=1315 for 1310 and 1550nm dual wavelengths, etc.
b: Optical Fiber Type, b=9 for 9/125 SMF; b=50 for 50/125 MMF; b=62.5 for 62.5/125 MMF, etc.
c: Pigtail Type, c=3 for 3mm jacket pigtail, etc.
d: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc.

Example: VOA-C-1550-9-1-SU
