Coils and Modules

Dispersion Compensation, Optical Delay, and Zero Dispersion

Berkshire Photonics is proud to offer custom optical precision coils and rack mount enclosures for use in telecommunications applications. They are available in three options: precision optical delays, zero dispersion, and dispersion compensating. All options can be purchased as stand alone coils or in a rack mount enclosure. Coils can be purchased with or without connectors already added. Enclosures can be purchased with pigtails or adapters. Berkshire Photonics stocks an assortment of aluminum spools and 19" enclosures, however custom spool and enclosure designs are available upon request. Please see additional information below.  

Dispersion Compensation Module

Part Number: 0301-N
