SERIAL-PARALLEL CHANNEL-COMPATIBLE TRANSMITTING DEVICE IN AN OPTICAL TRANSPORT NETWORK CAPABLE OF MANUFACTURING A SMALL OPTICAL MODULE OF LOW POWER BY MINIMIZING THE ADDITIONAL LOGIC OF A 40GBASE-FR OPTICAL MODULE AND A METHOD THEREOF

摘要

PURPOSE: A serial-parallel channel-compatible transmitting device in an optical transport network and a method thereof are provided to guarantee intercompatability between 40GBASE-LR4 optical modules or 40GBASE-FR optical modules and also guarantee intercompatability between an existing 40G 300pin MSA(Multi Source Agreement) optical module and a new 40GBASE-FR optical module.;CONSTITUTION: An SFI(SerDes Framer Interface)-5.2 interface unit includes an SFI-5.2 receiving interface unit(10) and an SFI-5.2 transmitting interface unit(13). An OTL(Optical Transport Unit)3.4 interface unit includes an OTL3.4 receiving interface unit(11) and an OTL3.4 transmitting interface unit(14). When a 40G 300pin MSA(Multi Source Agreement) optical module is interfaced with a 40GBASE-FR optical module, a 40G serial-parallel channel compatibility transmitting device(1a) and the 40GBASE-FR optical module are operated in an SFI-5.2 interface mode.;COPYRIGHT KIPO 2013
