GPON burst-mode receiver electronics prove challenging

摘要

While systems vendors have readied their GPON offerings for the RBOC showdown, they've had to do so without as much help as expected from their chip suppliers when it comes to burst-mode receiver electronics. Tighter timing parameters and a wider dynamic range make the GPON burst-mode electronics more technically challenging than their BPON and EPON counterparts. The business case for the merchant silicon vendors also may be proving less than attractive. The result is that module vendors have found themselves left to their own devices—literally—when it comes to the development of GPON transceivers.
