FOA is a plug-type single mode attenuator. It is used directly on the fiber optic connectors and provides a fixed level of optical attenuation. It has low return loss and works at both 1310nm and 1550nm wavelength range. FC and SC connector types with PC or APC polish are available, as well as ST and LC types of attenuators.

Features:

• Good repeatability
• High precision
• High return loss
• Small size
• Good directivity
• FC, SC, ST and LC types available

Application:

• Fiber communication
• Fiber CATV
• LAN
• Test equipment

Ordering Information:

FOA-a-b-c
a: ID of the operating wavelength; a=1310 for 1310nm, a=1550 for 1550nm, a=1315 for dual windows, etc.
b: Attenuation in dB; b=5 for 5dB attenuation; b=20 for 20dB attenuation, etc.
c: Connector type of the attenuator; c=FU for FC/UPC connector/adapter, c=STP for ST/PC connecctor/adapter, c=LU for LC/UPC connector/adapter, etc.

Example: FOA-1550-3-FA
