“…However, the number of optical devices used in this scheme increases linearly with the code length, which may lead to high cost when long codes are used. Recently, we have proposed an CDM over fiber system based on spatial coding and subcarrier multiplexing (SCM) [8]. The concept of electrical spatial encoding/decoding and SCM is illustrated in Fig.…”

The downlink transmission of a 1 Gb/s 15-user code-division multiplexing (CDM) over wavelength-division-multiplexing passive optical network (WDM-PON) based on electrical spatial coding and subcarrier multiplexing is experimentally demonstrated. Two wavelengths with 100-GHz spacing are used to carry the 15 spatial encoded subcarriers generated by an arbitrary waveform generator. Our results show that error-free operation can be achieved after 20-km standard single-mode fiber (SSMF) transmission when 15 simultaneous users are present assuming that forward-error correction coding is used.Index Terms-Code-division multiplexing (CDM), digital signal processing (DSP), passive optical network (PON), subcarrier multiplexing.

In this paper, we analyze the impact of analog-todigital convertor (ADC) bandwidth and clipping ratio on the performance of a 1 Gb/s × 15 user CDM-over-fiber-PON (COF-PON) system based on 16-QAM modulation, spatial coding and subcarrier multiplexing. We consider the clipping ratio, resolution and bandwidth of ADCs with fixed sampling speed in both back-to-back and 25 km standard single mode fiber (SSMF) transmission cases, taking into account nonlinear propagation effects in fiber transmission. We find that the best error vector magnitude (EVM) performance can be achieved when a clipping ratio (CR) of 1.5-1.8 is applied for different ADC resolutions, and that in order to achieve an EVM of smaller than 0.12, an ADC with at least 5-bit resolution should be used.

Electrically Processed OCDMA System Based on Spatial Coding and Subcarrier Multiplexing

Abstract: A low-cost electrically processed OCDMA system based on spatial coding and subcarrier multiplexing is proposed. The simulation shows that at least 10 simultaneous users can be supported in a 16-code OCDMA system with 40-dB OSNR.
