General Photonics’ fixed differential group delay (DGD) artifacts eliminate the need for precise measurement of PM fiber lengths to add defined amounts of first order PMD to a system. DGD values of up to 45 ps are available in the standard size package. Larger DGD values are also available by special request.
Applications
PMD emulation
PMD compensation
TDM bit alignment
Key Features
• Large 1st order PMD up to 45 ps
• Low insertion loss
