Variable Switched Delay Systems

The Optical Zonu Switched Delay Line System is a highly configurable 19” rack mount system that supports up to 212 (4096) switched delays (assumes three J-Chassis J-OPS plug-in modules). The RF input and output of the system are Optical Zonu RF over fiber pluggable modules that support the required RF frequency bands and RF performance. Optical switching modules control the routing through, or bypass of, discrete optical delay line elements. In this way, a maximum of 2N (N is the number of discrete delay elements) resulting delays may be realized. Alternately, N delays may be realized by selecting just one delay at a time.

Actual delays and delay resolution are customizable and fixed at the factory per customer requirement. Delays are based on actual fiber lengths in the delay spool chassis which is external to the J-OPS switching modules.

The RF gain through the system may be set to be proportional to the delay amount or may be set in an optical AGC mode where the system RF output is at a constant RF power level.

All RF over Fiber, Optical Switch, Power Supply, and JS14 Management & Control modules are pluggable and field replaceable. The system may operate from AC or -48 VDC power sources. The standard RF interface is 50 Ohm SMA, however specialized RF connectors may be required for the higher RF frequencies.

RF status and optical switching may be monitored and controlled via SSH command line interface, HTTP Web user interface, Optical Zonu J-Control graphical user interface, and/or SNMP v2 and v3 (see JS14 Managed Switch datasheet).
