Abstract

This paper introduces a new optical device model named as Optical Cross Add and Drop Multiplexer (OXADM) which is potentially useful in CWDM metro area network. The device uses the combined concepts of optical add/ drop multiplexing and optical cross connect between two main transmission lines in order to implement the wavelength routing operation [10]. Thermal-optical switches are integrated in the device to make it re-configurable. With its excellent features, the device is particularly designed to improve the network efficiency, flexibility and survivability [7, 8]. The device can be used in point-to-point, ring or mesh network topology to provide functionalities such as routing, supervision, transport, multiplexing and restoration of client digital signals processed predominantly in the optical domain [7]. The wavelengths on each optical trunk can be switched into each other while implementing add and drop functions simultaneously. The paper highlights on first experimental work on 2×2 OXADM prototype to measure OSNR values for single operation of OXADM. The results show the condition is in safe with (OSNR>20dB) for every function of OXADM. With 6 dB insertion loss, the maximum achievable transmission length by the OXADM is 71 km without amplification and the maximum achievable node is 6 units.
