JDS Uniphase SB0108-Z000522

The JDS Uniphase SB0108-Z000522 is a programmable optical switch that routes a single fiber optic input to multiple output channels, supporting up to 48 outputs in certain configurations. Bidirectional operation enables flexible signal routing in both directions. The unit delivers insertion loss as low as 0.5 dB (SM) or 0.4 dB (MM) typical, with switching speeds of 10 ms typical and 15 ms maximum. Lifetime exceeds 10 million cycles at 5 Hz duty cycle. ## Technical Specifications **Optical Performance**
