Variable Fiber Optic In-line Attenuators (VOA)

 

Introduction:
   To reduce signal power in a fiber-optic link. This precision devise can adjust the amount of attenuation, by very small amounts. It can also add large loss to an optical circuit.

Conceptual Usage:
    Attenuation is used, where signal power is too high. For example, in a fiber-optic link, a transmitter may overwhelm the receiver with too much power, or the link may be too short for adequate losses. In each case, too much power may damage or saturate the detector (i.e. receiver). Attenuation reduces the power to an acceptable or usable level. Variable attenuators permit the user, to control the level of power reduction.

 

Features:

•  - Complies with Telcordia GR-910
•  - Beam-blocking technique for higher power handling
•  - Pigtail fiber cable can be used as a cable assembly
•  - Connectors Types: SC, SC/APC, LC, LC/APC, ST, FC, etc.

 

Standard Configurations:

•  - Inline-style
•  - Pigtail fiber at both ends

 

Options:

•  - Fiber types:
        - Multimode (50/125 or 62.5/125)
        - Single-mode (9/125)
•  - Fiber pigtail lengths
•  - Connectors: with or without

 

Variable Fiber Optic In-Line Attenuator with Low Back Reflection -- Blocking Style.

Back Reflection: >40dB Attenuation Range: 2 to 80 dB with 0.01 dB Resolution up to 10 dB, with 0.1 dB Resolution up to 30 dB Attenuation. Wavelength Dependence: <0.3dB Change in insertion loss for 1310-1550 nm. <0.05 dB for 1525-1570 nm Available Wavelengths: 400 - 1625 nm * Bi-Directional: Yes Temperature Range: -35C TO +70C (less than 0.3dB in insertion loss). Humidity Range: +/- 0.2 dB Change in 10% to 90% Humidity Range. Drop Test: +/- 0.2 dB change after 4 drops from a height of 1 meter onto a hard surface. Vibration: Less than 0.05 dB change between 10Hz to 55Hz. Polarization Sensitivity: Less Than 0.01 dB change over all input polarization.

*Note: This attenuator is typically utilized for standard 1300/1550nm wavelengths. It can also be used for wavelengths from 1290-1625nm (it is ideal for CWDM, DWDM, L-Band and C-Band applications). For wavelengths >1290 please specify the exact wavelength required.
