Coherent optical components double optical fiber capacity

Electronics Wireless fiber optics fiber optics Optical opticalNEOPHOTONICS L-Band suite of coherent optical components includes 64 GBaud L-Band High Bandwidth Coherent Driver Modulator (HB-CDM), 64GBaud L-Band Intradyne Coherent Receiver (ICR) and ultra-narrow linewidth L-Band tunable laser Micro-ITLA. Together with firm’s standard C-Band coherent components, products enable customers to double the capacity of optical fiber links. The C-Band is the primary band for telecommunications with wavelengths centred around 1550nm. The L-Band uses wavelengths centred around 1590nm and is primarily used to complement the C-Band to increase data capacity, especially in long-haul networks. 64Gbaud coherent components and tunable lasers enable single channel 600G data transmission over data centre interconnect (DCI) distances of approximately 80km using 64 QAM.
