This product line is Telcordia qualified. Some Telcordia qualification data (PDF download) is provided (GR-1221-CORE, ISSUE 2) for a 1064 nm fiber to fiber isolator with maximum power handling of 20W. Excellent product stability is observed, via minimal changes in key isolator parameters, over 2000 hours of damp heat testing (85C, 85% RH) and temperature cycling over 500 cycles.
FeaturesDiffraction Gratings for optical communication are the components which take a key role in communication network system in the long term, and high reliability is demanded of them. These products have passed test in accordance with the Telcordia GR-1221-CORE which is required for the passive optical components.These are Au coated replica gratings from master diffraction gratings manufactured by using high accuracy two-beam interference. These have high relative diffraction efficiency for TM-polarized light*1 and are suitable for optical communication, industrial measurement across near infrared spectral regions which high performance and environment resistance are required.For more details, please contact us.

Note: MATH 1220 and MATH 1221 each cover one-half the material of MATH 1231. Because MATH 1221, MATH 1231, and MATH 1252 are related in their subject matter, credit for only one of the three may be applied toward a degree. Information on the placement exam, which is an option for placing into MATH 1051, MATH 1220, MATH 1231, or MATH 1252 is at: -mathematics-placement-test. 2ff7e9595c
