4.3.4 PON Transceiver Modules
PON transceivers still represent a very active area in industry research and
development due to the huge market opportunity. Because of the PON point-to-
multipoint nature, PON burst-mode transceiver must face several unique char-
acteristics to meet the requirements. Despite widespread interest, there is still no
related PON transceiver multisource agreement (MSA) defined to support this
application. Optical module vendors normally collaborate with system vendors
on a case-by-case basis in specifications for diverse systems. Because of the
EPON influence, SFF and SFP MSAs [44] gained some popularity, while other
form factors like GBIC [45] and proprietary triplexer designs still exist for this
application [46].
