Microwave Modules for Fiber-Optical

 

 

 

Our company, collaborating with ETRI (Electronics and Telecommunications Research Institute), has developed modules for 40 Gb/s clock and data recovery (CDR) in a fiber optical communication receiver. Our 40 Gb/s CDR module uses a phase-locked loop with a stable DRO source to reduce jitter of the recovered clock. The module integrates a DRO, multipliers, phase shifters, amplifiers, etc. to recover stable clock from 40 Gb/s binary signal, and to retime the input data with the recovered clock. We also offer low-cost phase shifters at 40/43 GHz with phase-locked loop technique.

 

Clock-Data Recovery Modules

 

 

Description:

The CDR-40G/CDR-43G module is a Clock and Data Recovery Module. This module extracts a clock component from 39~43 Gb/s NRZ signals, and stabilizes the signal using a phase-locked loop (PLL) with a dielectric resonator oscillator (DRO). In addition, this module contains phase shifters, and optionally retimes the input data with a decision circuit.


Features:

Low cost.

Low jitter in the recovered clock.

High-Q oscillator (DRO) is used.

Phase shifters at 40/43 GHz.

Minimum 130 mV single ended input signal is required.

Description:

The PS-40G/PS-43G module is a reflection-type analog phase shifter with a phase-locked loop (PLL) at 40/43 GHz. The input signal is phase-locked with a dielectric resonator oscillator (DRO), and continuously phase-shifted electrically. These PS series modules can be used to phase-shift 40/43 GHz clock signal for data retiming.


Features:

Uses phase-locked loop.

Produces constant output power.

Low return loss.

Low jitter.

Continuous phase shifting.

30 MHz bandwidth (with a mechanically tunable DRO).
