Abstract

In Dense Wavelength Division Multiplexing (DWDM) fiber communication system, more and more channels have to be put into a single fiber in order to fulfil the ever-increasing demand for high capacity. This put strict requirements on the wavelength characteristics of various active and passive optical components. Generally speaking, in current DWDM system, a wavelength accuracy of 5 pm is necessary for analyzing channel performance, and 0.5 pm is required for the aging test of components. An extended cavity laser diode (ECLD) frequency stabilized to saturated absorption lines of acetylene C2H2 with a potential long term frequency stability of 10-12 can provide excellent wavelength reference for DWDM communication system[1][2][3]. In this paper, we describe a practical 1.5μm wavelength transfer standard based on C2H2 stabilized DFB laser and tunable fiber Fabry-Perot etalon[4]. This transfer standard is suitable for the calibration of widely used optical spectrum analyzers (OSA) and wavelength/multi-wavelengths meters. This device is currently under development in the Quantum Division of National Institute of Metrology (NIM).
