Newport’s Single-Mode Fixed Attenuators offer low return loss, high mode stability and a variety of attenuation values: 3, 5, 10, 15 and 20 dB.
The F-FIA Series In-Line Attenuators are configured for dual window use at both 1310 and 1550 nm. Attenuation accuracy is <±0.3 dB for values up to 10 dB, and <±0.5 dB for values 10–20 dB. The one-meter fiber pigtails can be terminated in any one of 5 connector styles.
The F-ADAT Series Adaptor Type Attenuators are optimized for operation at either 1310 or 1550 nm and have a bandwidth of ±40 nm. These compact attenuators have a male connector at one end and a female connector at the other end, enabling them to be placed in the optical path without additional fiber pigtails and connectors. Attenuation accuracy is <±1.0 dB for values less than 10 dB, and <±10% for values greater than 10 dB.
