Multimode Inline Optical Attenuator

The MPS-2150 Multimode In-line Optical Attenuator is a “fixed value” attenuator that is integrated into a standard fiber optic jumper cable. MPS-2150 Multimode In-line Optical Attenuators utilize Corning fiber and are offered in two different connector brands; Our Corning line is built using Corning connectors and our Value line uses quality connectors at a substantial discount. They are available in a single window or dual window format with a user specified attenuation value up to 25 dB. The In-Line Attenuator is available in fiber diameters of 250 micron, 900 micron or 3mm and comes integrated into any length jumper. It can be supplied with or without connectors, or as a pigtail version. Every assembly exceeds Telcordia standards and is tested for insertion and return loss. In addition, each attenuator is individually tested and is supplied with it’s individual test record sheet.
