1550 nm造句

• Additional aerosol information is provided by a discrete photodiode at 1550 nm.
• Different fraxel systems use 10, 600 nm, 1550 nm Erbium, and 1927 nm Thulium lasers.
• The bandgap of InGaAs works well for detecting 1550 nm-wavelength infrared laser signals used in optical communication systems.
• Cr : YAG can be also used as a laser gain medium itself, producing tunable lasers with outputs adjustable between 1350 and 1550 nm.
• As of 2005, only 850 nm VCSELs are widely available, with 1300 nm VCSELs beginning to be commercialized, and 1550 nm devices an area of research.
• In these systems, the wavelengths used are often widely separated, for example the downstream signal might be at 1310 nm while the upstream signal is at 1550 nm.
• Some engines also received slight performance improvements, for example the DC9 engine that outputs 310 hp ( 1550 Nm ) was upgraded to 320 hp ( 1600 Nm ).
• As premises networks are primarily copper-based, media converters can extend the reach of the LAN over single-mode fiber up to 160 kilometers with 1550 nm optics.
• Each fiber pair has the initial design capacity of 8 wavelengths of around 1550 nm wavelength, which capable to carrying traffic at a data rate of 2.5 Gbit / s each.
• An additional factor with these systems is that light around the 1550 nm wavelength band ( common for optical amplifiers ) is regarded as relatively low risk, since the eye fluids absorb the light before it is focused on the retina.
• Dispersion Shifted Fiber is a type of single-mode optical fiber with a core-clad index profile tailored to shift the zero-dispersion wavelength from the natural 1300 nm in silica-glass fibers to the minimum-loss window at 1550 nm.
• The charts at " Understanding wavelengths In fiber optics " and " Optical power loss ( attenuation ) in fiber " illustrate the relationship of visible light to the IR frequencies used, and show the absorption water bands between 850, 1300 and 1550 nm.
• OS1 and OS2 are standard single-mode optical fiber used with wavelengths 1310 nm and 1550 nm ( size 9 / 125 祄 ) with a maximum attenuation of 1 dB / km ( OS1 ) and 0.4 dB / km ( OS2 ).
• Other, non-standard higher-powered single-strand optics commonly known as " BiDi " ( bi-directional ) utilize wavelength pairs in the 1490 / 1550 nm range, and are capable of reaching distances of 20, 40 and 80 km, or greater depending on module cost, fiber path loss, splices, connectors and patch panels.
• To provide 16 channels on a single fiber CWDM uses the entire frequency band spanning the second and third transmission window ( 1310 / 1550 nm respectively ) including both windows ( minimum dispersion window and minimum attenuation window ) but also the critical area where OH scattering may occur, recommending the use of OH-free silica fibers in case the wavelengths between second and third transmission windows are to be used.
