On top of regular two-port isolators, Primanex offers some special isolators such as 2-in-1 isolators, and WDM-Isolator hybrid (WDIH) etc. The 2-in-1 isolators integrate two isolators into the body of one regular isolator without any compromise in terms of optical performances, hence not only save cost for customers but also save precious space especially for space-demanding applications. The WDIH combines isolating and WDM functionalities into the body of one regular isolator, provides both savings and flexibility for customers.
