2 April 2003 Berlin, Nuremburg, Germany -- Measurement module specialist SHF Communication Technologies and modules and subsystems developer CoreOptics are jointly developing a stand alone clock recovery module for 40Gbit/s component testing, transmission system and fibre loop experiment applications.
The module extracts a clock frequency of half the input bit rate from both RZ and NRZ signals. Optionally, a full 40GHz clock output can be provided, as well as up to two internal reference oscillators selectable from a range of fixed frequencies. These features will enable the users to test the full range of standard and FEC-supported line codes.
The key element of SHF's clock recovery solution is CoreOptics' small form factor multi-chip module (MCM). The MCM is based on a thermally enhanced ceramic substrate using CoreOptics' ultra high-speed SiGe mixed-signal integrated circuits in a flip-chip mounting configuration.
"This clock recovery module provides extremely low jitter clock signals from RZ or NRZ signals even at data signal input levels below 50mV," said Michael Martin, CTO at SHF.
"We are excited to enable SHF to build compact stand-alone clock recovery solutions at 40 and 43Gbit/s with our IC and MCM technology. This should help SHF to improve its 40Gbit/s test suite", said Christoph Schulien, CoreOptics' VP of Business Development for Europe and Asia.
