Cov kev txhim kho latency tau sib txawv los ntawm kev txuas ntev thiab kev cia siab suav. Rau luv -} mus txog cov ntaub ntawv sib txuas (<100m, 2-3 hops), MTP typically reduces total latency by 50-150 nanoseconds through reduced insertion loss and processing overhead. For longer metropolitan links (2-10km, 5-8 hops), the improvement can reach 400-800 nanoseconds by eliminating regeneration sites.
Puas yog MinTP innetors haum rau sab nraum zoov fiber ntau cov khoom siv?
Txheem MTP cov txuas txuas yog tsim los tswj cov chaw ib puag ncig hauv tsev. Sab nraum zoov xa yuav tsum tau Ruggedized MTP cov variants nrog txhim kho cov ntaub ntawv ntawm ib puag ncig, thiab nthuav tawm kev ua haujlwm kub siab (-40℃rau {}}} degree). Cov rooj sib tham tshwj xeeb no tswj hwm cov yam ntxwv poob qis thaum muaj cov dej noo, UV raug, thiab qhov kawg.
Yuav MTP Innitors Txhawb nqa yav tom ntej 800g thiab 1.6T tus mob tus nqi?
Yog lawm, MTP cov neeg kho tshuab tsim kev txhawb nqa tam sim no thiab yav tom ntej kis tau ceev. Qhov txwv tsis yog qhov txuas tab sis theej qhov transceivers thiab fiber ntau. MTP - 16 thiab MTP-24 kev teeb tsa muab Fiber txaus suav rau 800g thiab 1.6t parallel optics siv. Cov hom fiber ntau (OS2, om5) ua ke nrog cov neeg tseem ceeb ntawm cov neeg tseem ceeb MTP cov peev txheej tau ntsib cov kev siv nyiaj poob qis cov kev xav tau sai.
