Iinkcukacha ezikhawulezayo
Cense wavelength division multiplexer(CWDM) is based on the membrane filter technique and proprietary non-flux metal bonding micro-optics packaging design, within ITU wavelengths to achieve uplink and downlink. It provides ITU channel center wavelength, low insertion loss, high channel isolation, low power consumption, wide passband characteristics, no glue loop, excellent thermal stability and reliability and so on. In a telecommunications network system, it can be used for uplink or downlink optical signal.

FAQ
Q1. Ndingayifumana isampulu yoku-odola le mveliso?
A: Ewe, simkela isampula yovavanyo ukuvavanya nokujonga umgangatho. Iisampuli ezixubileyo ziyamkeleka.
Q2. Kuthiwani ngexesha elikhokelayo?
A: Isampulu idinga iintsuku ezingama-1-2, ixesha lokuvelisa ubuninzi lifuna iiveki ezi-1-2.
Q3. Ungayithumela njani impahla kunye nokuba kuthatha ixesha elingakanani ukufika?
A: Siqhele ukuthunyelwa ngeDHL, i-UPS, i-FedEx okanye i-TNT. Ngokuqhelekileyo kuthatha iintsuku ze-3-5 ukufika. I-Airline kunye nokuthunyelwa kolwandle kwakhona kunokuzikhethela.
I-Q4: Ngaba unika isiqinisekiso malunga nemveliso?
A: Ewe, sinika iwaranti yeminyaka emi-1-2 kwiimveliso zethu ezisesikweni.
Q5: Kuthekani ngexesha lokuhambisa?
A: 1) Iisampulu: kwiveki enye. 2) Iimpahla: Iintsuku ezili-15 ukuya kwezi-20 ngesiqhelo.
