Modified Square Lattice Photonic Crystal Fiber (SLPCF) Incorporating EDFA and Definite Power CW Laser for Improved RoF Link

In this work, a modified SLPCF Radio-over-fiber (RoF) link incorporating erbium doped fiber amplifier (EDFA) and continuous wave (CW) laser of definite power is proposed as a new approach of forward error correction (FEC). In particular, the RoF model operates with CW laser driven at 1 dBm, 10 dBm and 15 dBm input powers. The model is simulated considering 1010 bit sequence and the results are compared with those using conventional SMF and previously described SLPCF configuration. We observed that the proposed RoF link produces reduced dispersion and BER, sharper eye diagram and both the improved Q-factor and eye height. Thus, the performance of the RoF link using modified SLPCF incorporating EDFA and CW laser definite power is noticeably improved, therefore, the model can be useful for cost-effective RoF link design.
