Although both Princetel's MJX and RPTPC series FORJs can be used under water (2,500 psi and 5,000 psi respectively), the RPC series was designed for the ultimate pressure (20,000 psi). Standard units come with stainless steel armored jackets, which can be terminated with ST, FC, or SC connectors or their APC counter parts.

Similar to model RPT, RPC features extremely low insertion loss and high return loss performance for both singlemode and multimode fibers. Model RPCA guarantees 50 dB return loss. These rugged devices can operate under arctic temperature environment (See insertion loss and return loss temperature cycling plots on the left).
