Product information "FDE-002 Fixed Differential Group Delay"
1550 nm; DGD 0-45 ps; RL 55 dB; IL 0.8 dB; Fiber Type SMF-28; PDL <0.2 dB
General Photonics’ FDE-002 fixed differential group delay (DGD) artifacts eliminate the need for precise measurement of polarization maintaining (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 FDE-002 fixed differential group delay standard size package. Larger DGD values are also available by special request.
