OPTEK to develop POF components for industrial control Product News 1/10/2005 Post a comment OPTEK Technology, a subsidiary of TT electronics, is developing a series of plastic optical fiber (POF) products as a replacement for traditional copper wiring that are designed to support the SErial Real-time COmmunications System (SERCOS) interface protocol for industrial control applications. SERCOS is an open, standardized digital interface for fiber optic communication between digital controls, motor drives, I/Os, sensors and actuators in computer numerical control (CNC) systems.
Reflective optical sensors operate up to 40 mm Product News 1/6/2005 Post a comment A new reflective optical sensor from Vishay Intertechnology is capable of detecting objects at operating distances of up to 40 mm. The new surface-mount TCND5000 reflective sensor also integrates an IR emitter and PIN photodiode in a single package. This new device is designed for use in object presence sensors, touch sensors, and proximity sensors in a broad range of consumer, industrial, and automotive applications.
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.
