The presence of common-mode noise in differential lines is a major contributor to signal integrity problems in high-speed digital systems. Common-mode noise is typically excited by skew. It can occur due to timing mismatches at the driver, length mismatches due to routing constraints, or phase velocity mismatches due to inhomogeneous dielectrics with fiber-weave effect. Common mode noise results in...
A compact 8 lane Integrated ROSA with low optical loss 1:8 Optical de-multiplexer is developed. The package size is 22.3 mm × 12.0 mm × 5.3 mm. The total optical insertion loss is estimated to be 1.0dB.
The fiber optic data transmission system plays an important role in broadband communication. According to the market trend, data traffic is significantly increasing and larger throughput of communication systems is required. Many opto-electronic conversion devices (so called optical transceivers) are used in the system. Because of that, the electro-magnetic noise radiation becomes a serious consideration...
