C Band Wavelength Tunable Laser Module


The TWL-C-B-M is a wavelength tunable laser module in C-band based on integrable tunable laser assembly (ITLA). The TWL-C-B-M alleviates inventory and costs in high-channel-count DWDM systems by allowing a single device to replace each of the single-channel devices. Full-band tunable assemblies also enable system functionality such as hot back-up and dynamic provisioning in addition to applications of optical regeneration and wavelength conversion, with the HP version also including a built-in sweep function for continuous scanning applications. The TWL-C-B-M has a low Relative Intensity Noise (RIN), a high Side-Mode Suppression Ratio (SMSR), an ultra narrow linewidth, and excellent wavelength accuracy. Its RS232 control complies to OIF ITLA Multi Source Agreement (MSA) standard, with a provided GUI software for intuitive control of the wavelength and optical power. The TWL-C-B-M can be used for Dense Wavelength Division Multiplexing (DWDM) optical Transceivers and DWDM discrete line card design. The TWL-C-B-M requires a single ±5 Volt DC power supply for operation.
