the optical property of XFP is only slightly after

XFP modules are hot-swappable and protocol- independent. 2. They typically operate at optical wavelengths (colors) of 850 nm, 1310 nm or 1550 nm. 3. Principal applications include 10 Gigabit Ethernet, 10 Gbit /s Fibre Channel, Synchronous optical networking (SONET) at OC-192 rates, Synchronous optical networking STM-64, 10 Gbit /s Optical Transport Network (OTN) OTU-2, and parallel optics links. 4. They can operate over a single wavelength or use dense wavelength-division multiplexing techniques. 5. They include digital diagnostics that provide XFP solution management that were added to the SFF-8472 standard. 6. XFP modules use an LC fiber connector type to achieve high density.

At the same time, Menara Networks has implemented the optical transmission network (OTN) of ITU-T in the XFP application in the form of specific integrated circuit (ASIC). OTN used in adding optical performance monitoring function and transmitting error correction, at the same time, for signal transmission package. Through the integration of OTN in the plug-in package, package, the functions of signal package, achievable rate and optical signal management can be added to the IP routers and carrier Ethernet switch routers. This design has several advantages: the C-Band tunable elimination of the needs of using additional 10 Gbps transponder to transmit switch or router signal (for DWDM transmission), and allows system suppliers to develop universal card without support OTN. But the biggest technical problem for Menara is the development of the included software rather than the development of OTN ASIC.
