Notes:  
1. 
Optical input power of -3.0 dBm (-20 dBm for the low input version) or greater is required to maintain the full user-settable threshold 
range.  When the optical input power is less than -3.0 dBm (-20 dBm for low input version) there is a 1-for-1 reduction in threshold range.  
Module will remain in Primary (default) state regardless of Primary input level if Secondary input level is below its switching threshold. 
2. 
Insertion loss of module with 0.5 dB loss per mated connector pair for a total connector loss of 1.0 dB.  Actual loss may be less 
depending on mating connector compatibility. 
3. 
With APC connectors. 
4. 
When operating at ambient temperatures below 0
°C, the power consumption can be up to 15W. 
5. 
Air inlet temperature to Prisma II chassis in non-condensing environment.  Up to 10 minute warm-up time required for start-up below 0
°C 
(32
°F). 
6. 
Recommended for use only in non-condensing environment. 
7. 
On low input version, switching time can be delayed from 0 to 1 second in 50 ms increments.  0 seconds is the default. 
 
 
 
 
 
 
 
Unless otherwise noted, specifications reflect typical performance and are referenced to 68
°F (20°C).  Specifications are based 
upon measurements made in accordance with SCTE/ANSI standards (where applicable), using standard frequency assignments.
