Performance Investigation of VCSEL based High Speed Optical Networks

---

Abstract

In this paper, a Vertical Cavity Surface Emitting Laser (VCSEL) based high speed optical network has been established. VCSEL’s operating at 1550nm has been a very promising source used in optical networks because of their technologically attractive properties and broad range of applications. We have established the link for data transmission at the bit rate of 20Gbps with 10km fiber length at 1550nm wavelength and an operating temperature range of 30°C to 85°C. We have further studied the change in performance parameters of the model by comparing two models i.e. one by employing Erbium Doped Fiber Amplifier (EDFA) and Semiconductor Optical Amplifier (SOA)both (Hybrid Model) and the other one by employing EDFA only. With our proposed system, we have achieved maximum Q-factor of 23.68 and BER<10-12.
