10G APD Photodetector AT10GC Bookham(Oclaro)
The detector has a fiber tail fiber input with a speed of 10Gbps and a built-in low noise preplay.It can be used for digital optical fiber communication.The sensitivity can reach -26.5dBm and the saturation light power -1dBm.It can work in the C and L bands and output differential voltage swing 1000mVpp. The AT10GC receiver consists of an avalanche photodiode,a low-noise preamplifier and a precision NTC thermistor in a hermetic coplanar package with a connectorized single-mode fiber pigtail.Differential outputs are provided to improve noise rejection for enhanced sensitivity. It has been optimised for use in 10Gb/s metro applications,either as a discrete device or within a transponder,using NRZ modulation,with or without FEC,at data rates up to 10.709Gb/s.
