ESL rolls out fiber-to-RS485/422/232 interface converter Product News 7/2/2007 Post a comment Aimed at defense applications, Electro Standards Laboratories' (ESL) Model 4149 high speed ruggedized fiber-to-RS485/422/232 interface converter provides typical operating speeds of 1.5-Mbits/s for RS232 to fiber conversion and 20-Mbits/s for RS485/422 to copper conversion.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
