Prisma II 1310/1550 nm Optical Switches 
 
Features 
•  2X2 switch component for outstanding flexibility 
•  Provides redundancy for 1550 nm or 1310 nm systems 
•  Switch hysteresis prevents the switch from returning to primary input until input 
is stable 
 
•  Large optical power dynamic range: 
Standard Input 
-13 to +18 dBm @ 1550 nm 
-13 to +13 dBm @ 1310 nm 
Low Input 
-30 to 0 dBm @ 1550 nm 
-30 to 0 dBm @ 1310 nm 
 
•  Activated by one of three methods 
- Loss of light 
- Local Craft Interface (LCI) 
- ROSA / TNCS software 
 
•  Status LEDs indicate module condition and simplify troubleshooting 
•  Time delay setting (set by user) prevents false reactivation of switch before a reliable signal has been 
restored 
•  Input power threshold set by user determines when switching occurs 
•  Can be connected to an external alarm system 
•  Multiple set-up and control options 
Local control via Local Craft Interface (LCI) 
Local control via Intelligent Communications Interface Module (ICIM) 
Remote monitoring via ROSA / TNCS software
