In IWDM, central Bragg wavelength detection technique is a very important issue to detect each FBG central wavelength even when two or more FBG spectra are partially or fully overlapped [18].
Moreover, we propose IWDM to increase the number of FBG sensors and we employ a Raman amplifier to increase the sensing signal transmission distance and to improve the signal quality.
The schematic diagram of applying IWDM and ELM techniques to a FBG sensor system is explained by using three FBG sensors as shown in Figure 1.
IWDM technique can increase the number of FBG sensors to be multiplexed by keeping the same dynamic range for each FBG sensor [8].
ZTE Corporation, a provider of telecomms equipment and network solutions, has launched the next-generation iWDM (intelligent Wavelength-Division Multiplexing) solution integrated with Wavelength Switched Optical Network (WSON), Photonic Cross-Connect (PXC), L2 switch and Optical Transport Network (OTN) technologies to help operators address present and future network transmission challenges.
According to the company, iWDM delivers flexible IP bandwidth management and aggregation functions and enables the efficient management of large granule services including GE/10GE, as compared to conventional WDM equipment, which only serves as an optical fibre channel.
ZTE's iWDM product family consists of the ZXWM M920 long-haul optical network system; the ZXONE 8600 large capacity optical cross-connect network system; the ZXMP M820 metro optical network product; and the ZXMP M720 metro edge optical network product.
Using Intelligent WDM (iWDM) technology, Layer 2 functionality and flexibility, it provides network operators and enterprises with a plug-and-play experience, reducing network and service turn up times, cost and complexity, the company said.
