Design and characterization of dispersion compensating fiber based on the LP/sub 01/ mode

摘要: The practical implementation of erbium-doped fiber amplifiers with gain at 1.55 /spl mu/m allows long unrepeatered transmission distances. However, in order to realize high data rates over these distances already installed standard single mode fiber, techniques must be found overcome the pulse spreading due positive chromatic dispersion this window, we review a compensation technique based on propagating signals through specially designed large negative for LP/sub 01/ mode, thereby ending up zero net spreading. basis concept are discussed and key figure merit compensating devices is defined. design optimization (DC) described special attention concerns including packaging manufacturability. We describe experimental fabrication results DC using make compact modules, outcome recent systems experiments incorporating fiber. >
