Fixed Type Attenuator
Introduce
Fiber optic attenuators are used in the fiber optic links to reduce the optical power at a certain level. Adaptor type fixed attenuator are available for singlemode LC, SC, ST, FC types, select from 1310nm or 1550nm, all the products are rigorously tested to meet the needs of optic network, compliance with ROHS standard.
