OTOA-1000 – In-Line, Step-Variable, Singlemode Optical Attenuator

Description

• Low-cost method for adding step-variable optical attenuation without interrupting connections
• Passive device intentionally induces macrobend losses around a series of restrictive curvatures
• Combination of 1dB, 2dB and 4dB “loops” provides step-variable attenuation from 1dBthru 7dB
• Built-in strain-relief mechanismminimizes changes in attenuation over time and temperature
• Ideally suited for single mode 1310nm applications, including:
• Reduction of the optical signal at the receiver to attain the “sweetspot”
• Optical receiver protection during initial optical transmitter turn-up
• CATV/HFC video and high speed data distribution networks
• PON (passive optical networks)
• Laboratory testing
