MARCH 25, 2010 -- Mitsubishi Electric Corp. has developed a dual-rate, burst-mode optical transceiver that enables the coexistence of GE-PON and 10G-EPON, which is used in optical line terminals.
This announcement is being made at OFC/NFOEC2010 (Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference) in San Diego.
Company officials anticipate that the transceiver will be integral to cost effectively installing 10G-EPON systems on existing fiber plant networks. It will enable the optical access system to provide a faster, more economic connection by using existing optical fiber networks effectively.
Part of this work was supported by the National Institute of Information and Communications Technology.
Mitsubishi Electric developed optical devices (EML, DFB, APD-preamplifier) and a triplexer optical module, which meet the IEEE802.3av PR30 standards. They are integrated into a XFP-E-sized 2R transceiver. Their transmission performance enables a loss budget of 29dB, split ratio of 32, and a maximum transmission distance of SMF 20km, utilizing existing fiber plant networks for coexistent GE-PON and 10G-EPON systems.
