This paper has experimentally demonstrated and analyzed the performance of 2.5-Gb/s × 3-channel upstream transmission in electrical code divided multiplexing-orthogonal frequency division multiplexing access (ECDM-OFDM) passive optical network (PON). The colorless upstream link can be realized in ECDM-OFDM-PON. The experimental results show that the performance degradation due to optical beating interference (OBI) noise can be well suppressed in this network when the three channels adopt the same upstream wavelength. Compared with the WDM-OFDM-PON upstream signals without ECDM, the error floor shows about three orders of magnitude improvement due to the code gain when the same wavelength is used for all upstream signals.
