Bulkhead Attenuator

Bulkhead attenuator also called fixed fiber-optic attenuators. Bulkhead attenuators used in fiber optic systems may use a variety of principles for their functioning. Preferred attenuators use either doped fibers, or miss-aligned splices. Inline style attenuators are incorporated into patch cables.

The alternative build out style attenuator is a small male-female adapter that can be added on to other cables. Non-preferred attenuators often use gap loss or reflective principles. Such devices can be sensitive to: modal distribution, wavelength, contamination, vibration, temperature, damage due to power bursts, may cause back reflections, may cause signal dispersion etc.
