APPLICATION NOTE 4922

Design a Low Power Consumption Optical Module Using PHY1040


Abstract: The Phyworks PHY1040 is a VCSEL/laser driver and limiting amplifier for use within fiber optic modules for SFP and SFF applications. This application note explains how to reduce the power consumption of a PHY1040-based optical transceiver module. The power-saving techniques that are discussed include disabling some of the device’s features and reducing bias trims. The document also shows how to calculate the IC’s current consumption at various bias and modulation current settings.
