The Optokon SFT-S35-01×02-50-CAPM-NPC-NPC is a singlemode fiber optic splitter engineered for dual-window operation across the 1310 nm and 1550 nm bands. This 1×2 fused-technology splitter delivers 50:50 coupling with typical excess loss of 0.2 dB and maintains exceptional performance stability across wide temperature and wavelength ranges. It is housed in an OPTOKON cassette package with NPC connectors on all ports.
