PON evolution start from APON, BPON and now it is time for GPON and EPON to dominate the FTTH network, however for future deployment EPON already have clear path to upgrade from 1Gbps for upstream and downstream to 10Gbps both upstream and downstream. For GPON network, these technologies still enjoy 2.5Gbps downstream and still not have clear path to catchup with EPON technology. By using WDM technology GPON try to deploy multiple wavelength to carry more bandwidth to compatible with 10GEPON network in the future. In CWDM PON system project proposed by TMR&D, the combination of EPON that can provide simple network through Ethernet packet can manipulate WDM technology by using CWDM PON system in the network. TMR&D is one of the pioneer that provide CWDM PON system already proof the prototype concept that EPON can be combine with multiple CWDM wavelength to provide more bandwidth with simple Ethernet packet transmission. TMR8D proof the system can provide 4 wavelengths by using CWDM wavelength in a single board. Using AWG, all 4 wavelength multiplex and carried by Fiber link up to maximum 20km to the nearest premises. Using second AWG de-multiplex the wavelength each of wavelengths will be split into maximum 32 users. Every 32 user will shred the same wavelength. This concept combining two technology which is TDM that used by EPON and GPON and also WDM technology to maximized the number of wavelength carried into a single fiber.
