Introduction

introduction

The HP OmniBER 717 is a modular, portable analyzer that supports optical and electrical interfaces for TCarrier, PDH, SONET, SDH, ATM, jitter and LAN applications from 704 kb/s to 622 Mb/s (OC-12/STM-4).

The HP OmniBER 717 has an easy-to-read color display. It offers an extensive range of T-carrier, PDH, SONET, SDH, ATM, jitter and LAN measurements.

Each analyzer provides dedicated slots for an optical interface and the printer/ remote-control module, plus up to eight slots for other interface and measurement modules. This provides the analyzer with the flexibility to offer dedicated modules for T-Carrier, PDH, SONET/SDH, SDH only, ATM, and jitter which can be combined together in the one mainframe enabling a range of test requirements to be covered.

The test and interface modules offer a range of measurements including detailed overhead, parity and alarm testing as well as frequency offset tolerance

tests, frequency measurement and optical power measurement. The analyzers also offer enhanced test features like pointer sequence generation, overhead access and manipulation, overhead sequence generation and capture, service disruption measurement, plus thru mode capability. The structured T-carrier and PDH modules also offer ITU-T M.2100/ M.2101/M.2110/M.2120 testing with comprehensive ITU-T G.821 and G.826 in-service and out-of-service analysis. Dedicated test hardware provides all results and analysis simultaneously, so all relevant measurements are made in one test run saving time and hence money.

For transmit and receive testing of short-, intermediateand long-reach optical circuits, there is a choice of 1310 and/ or 1550 nm OC-1/STM-0, OC-3/ STM-1 and OC-12/STM-4 optical modules. Electrical interfaces at STS-1/STM-0 and STS-3/STM-1 are also available, as are jitter generation and measurement interfacing options.
