HP 59552A Fiber Optic Distribution Amplifier

The HP 59552A Fiber Optic Distribution Amplifier provides a simple, modular approach to signal routing. The fiber-optic products provide clean, timing-quality transmission for precise frequency and time signals, or distributing timing signals for applications including the analysis, monitoring, and control of power utility substations. In a typical application requiring distribution of one pulse per second (pps) and IRIG-B time code, the HP 59552A provides an identical, synchronous clock signal and precise time of day to every distribution point.

The HP 59552A Fiber Optic Distribution Amplifier, used with HP 59553A Fiber Optic Receivers, receives a digital (TTL) signal and an analog signal via two BNC connectors. The distribution amplifier combines the signals, and transmits the result on eight fiber-optic outputs. Signal integrity is maintained over fiber-optic cable lengths of up to one kilometer. One HP 59553A is required for each of the outputs used.

[ Features ]

Configurable for two distribution modes
High-integrity distribution meets stringent requirements
Electrical noise immunity of fiber-optic cabling
Front panel LEDs provide quick status indication

Complete Compatibility

The HP 59552A distribution amplifier is completely compatible with the HP 59551A, which provides high-quality timing signals (both 1 pps and IRIG-B) as standard back panel outputs.

Configurable

The unit is factory-configured for "combined mode" to distribute one analog and one digital signal. If your application requires transmission of only one digital signal, the HP 59552A can be reconfigured for "digital mode" to pass signals without the delay or throughput restrictions associated with combining digital and analog information.
