The F-CPL-2x2-OPT 2 x 2 Fiber Optic Coupler is configurable based on your needs. Please specify the input connector, output connector, and 2 x 2 coupler model at time of quote. Standard connectorization options (except for F-CPL-S22151) are FC/APC on all ports. FC/UPC can be ordered on all ports as well. For all other connectorization options (including ST, FC/PC, FC/APC, SC/PC or SC/APC) please call Newport. Connectorized couplers can be used directly with our 918D or 818 series detectors using any of the various fiber adapters offered by Newport and the 818-FA fiber adaptor mount.
