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
-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
- 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
