Optical attenuators

Frequently asked questions

 

Fibre coupled variable attenuator(VOA)
VOA is fiber coupled device easy to work with any application . It features low insertion loss, wide attenuation range, small package and it is easy to operate. The attenuation range is from 0 to 40dB, and is continually adjustable. They come with single wavelength and dual wavelength. Variable optical attenuator can supply with FC/UPC, FC/APC, SC/UPC, SC/APC or LC connector types.
- Wavelength: 1310/1550nm
- Singlemode SMF28 fibre
- 0.8~40dB variable range

Fibre coupled fixed attenuators(in-line)           
Fibre coupled attenuators available with SMF28 fiber or Hi1060 fiber and jacketed with 900um loose tube or 3mm tubing. In-line attenuators can be supplied with unterminated or with FC/APC, SC/APC or E2000 connectors. Other terminations are available.
- Wavelength: 1064, 1310 or 1550nm
- Singlemode fibre: SMF28 or Hi1060
- Attenuation values:  5dB, 10dB, 15dB and
  20dB or specify

Fixed adaptor type optical attenuators
Low cost 1310/1550nm Fixed optical attenuators 
are widely used in laboratory testing, optical 
communication systems, CATV, LAN, test 
and measurement.

- SC or FC plug type
- Attenuation values: 3, 5, 10, 15 and 20dB
- Low back reflection
