A proprietary, passive, input matching circuit ensures that the no energy is reflected in the stopband. The SL070 is a five pole design, optimised for OC192/STM-64 systems. Other designs for OC48 and OC768 are available on request. Bessel Lowpass Filter SL070 Series Mechanical & Environmental • • • • • SMA Connectors Epoxy Sealed Black Epoxy Finish Through Mounting Holes -30 to +70C Filtronic Components Limited, Airedale House, Acorn Park, Charlestown, Shipley, West Yorkshire, BD17 7SW, England Tel: +44 (0) 1274 531 602, Fax: +44 (0) 1274 595 724 Filtronic Components Inc. 11 Huron Drive, Natick, MA 01760-1314 Tel: (508) 653 0844, Fax: (508) 653 5671 E-mail: sales@fcl.com, www.filtronic.com Filtronic reserve the right to change this specification without notice, no liability is accepted for omissions or errors
