HP 87441A STM-1/OC-3 Filter

The HP 87441 family of filters is designed for use with broadband optical/electrical converters used in transmitter eye-pattern conformance testing. The filters are measured to comply with Synchronous Digital Hierarchy (SDH), Synchronous Optical Network (SONET) and Fibre Channel standards. The HP 87441 family is fourth-order, Bessel-Thomson, low-pass filters that have –3 dB cutoff frequencies at 0.75 x the data rate of the SDH, SONET, and Fibre Channel rates being used. Each filter is supplied with measured performance data that meets the ITU-TS G.957 standard for frequency response.
