Filtronic Suspended Substrate Stripline low-pass filters for optical communication
systems have been designed with a Bessel phase performance and are suitable for
use in TX/RX systems for pulse shaping and noise reduction and in BER test sets. 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.
