A semi-ruggedized housing, used on 1x2 and 2x2 couplers at 633, 780, and 850 nm, consists of a stainless steel outer housing from which 1 m long, 900 µm buffered fibers exit through molded strain relief boots. 【Packing Included】The package contains SC, FC, ST, LC/UPC, SC/UPC-SC/APC, FC/UPC-LC/UPC interchangeable connectors. Optical Connectors Kits are compatible with most SC/FC/LC/ST fibers. 【Low Insertion Loss】OTDR connectors offer precise signal transmission, minimizing signal loss and maintaining. The F-CPL-B12355-FCUPC Broadband Coupler is operational over both the 1310 and 1550 nm windows. This 1x2 coupler has a 50/50 (3 dB) coupling ratio. The F-CPL-B12355-FCUPC can be used directly with the 918D-IS-1 fiber optic detector. It can also be used with the 818 or 918D. 【Dual port PON full link compatibility test】The dual port direct design (1310nm uplink+1490/1550nm downlink) ensures that OLT to ONT communication remains active during testing, and ISP/FTTH installation will not interrupt service. 【Three wavelength accuracy, with an accuracy of ± 0. It further improves display brightness and clarity, greatly enhancing.
