Tham khảo tài liệu 'wdm lan optical backbone networks phần 5', kỹ thuật - công nghệ, kĩ thuật viễn thông phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | the elements of succes Single Mode vs. Multi-Mode for WDM Applications Glass optical fiber options include SM and MM fiber qualifications for selecting use of MM or SM include Many feature-rich components COTS and integrated components being developed for telecom applications are geared for SM applications Potential WDM options with MM are limited to systems with fewer wavelengths than SM MM has limited ability to support fine-grained DWDM Difficult to support MM amplified systems if amplifiers are needed to overcome connector and or WDM network component losses. Hard to support desired bandwidth density and signal formats . for analog applications in MM fiber. MM not as future proof as SM - may be able to support transport of signals over MM fiber but limited in the types of devices and systems that can be interconnected over MM links. CWDM TFF Fe a t u res Be lie fits - Low thermal drift spectrum - Wide passhand - High isolation at transmissi and reflection - Low inserti m loss - Epoxy-fire optical path - Totally passive thin film filters Dimensions Ural 71 .Til MM and SM systems can use similar laser and modulators SMFhandMMFcnetworkrcomponents include are designed for SM Laser Modulator Receiver Detector Amplifier optional Filter Combiner including CWDM components While SM components are more costly DWDM and SM devices are likely to achieve lower size and weight through integration vs MM and or CWDM devices. SM devices typically support a wider range of functionality and are widely available leveraging telecom applications - generally easy to find desired functionality in existing components. 41 tfTelcorc the elements of succes Connectors for Aircraft Optical Fiber Networks Performance characteristics for MC5 optical fiber connector from Deutsch. The MC 5 is the standard multiway fibre optic connector for the European Fighter Aircraft Typhoon OPTICAL PERFORMANCE Insertion loss typical Return loss typical Repeatability .
