Keysight (Agilent) 3787B Digital Data Test Set

The HP 3787B Digital Data Test Set is a Bit Error Rate Tester (BERT) designed for use on TI leased , Digital Data System (DDS), 56 kbit/s switched and Packet Switched services transmission line and multiplexing equipment. Digital data circuits are sold with a guaranteed Quality-of-Service (eg DDS circuits offer >99.5% Error Free Seconds in a 24 hour period and 99.95% Availability). To maintain this high quality of service, Service Providers need test equipment that will provide in-service network monitoring and fast out-of-service testing. Operating Frequency: DS0 (64kbit/ s), DSI (1.544Mbit/ s) , DS1C (3 .l52Mbit/ s). Framing: DS1 (SF, ESF, T1DM and Ft only), DS1C and DS0B. Line Code: B8ZS, AM1. Error Types: Logic (Binary) , Bipolar Violations, Frame Word, CRC-6 Word. Error Results: Error Count, Error Ratio, Error Seconds, Error Free Seconds, % Error Free Seconds. Error Analysis: % Availability, % Unavailability, % Severely Errored Seconds, % Error Seconds, % Degraded Minutes, Count Consecutive SES, Count SES, Count ES, Count Deg Min. Alarm Seconds: Instrument Power Loss Seconds, Signal Loss Seconds, A1S Seconds, Frame Loss Seconds (ie DS1C, DS1 or DS0B), Test Pattern Loss Seconds. Frame Slips (Controlled): Duplicated frames are indicated as positive frame slips. Deleted frames are indicated as negative frame slips.

Data Rate
Data Rate is the maximum number of bits of information which can be transmitted per second, as in a data transmission link. Typically expressed as megabits per second (Mbps).

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

SONET
Synchronous Optical NETwork (SONET) is a fiber-optic transmission system for high-speed digital traffic. Employed by telephone companies and common carriers, speeds range from 51 Mbps to 40 Gbps. SONET is an intelligent system that provides advanced network management and a standard optical interface. Specified in the Broadband ISDN (B-ISDN) standard, SONET backbones are widely used to aggregate T1 and T3 lines. The European counterpart to SONET is the Synchronous Digital Hierarchy, and the term "SONET/SDH" is widely used when referring to SONET
