JDS Uniphase SB1C10081+27XF000SC

The JDS Uniphase SB1C10081+27XF000SC is a 1×8 optical fiber switch engineered for signal routing in telecommunications and data networking infrastructure. It directs optical signals across eight output channels from a single input, enabling rapid reconfiguration of fiber optic test paths and network topologies. The switch employs JDS Uniphase expanded beam lens technology with precision stepper motor alignment to achieve low insertion loss and exceptional return loss performance. Single-mode fiber compatibility across the C-band and L-band wavelength range makes it suitable for broadband testing applications.
