18ch CWDM With Ultra Low Loss Attenuation In Metro Links
Oct 08, 2018

Arkoptics manufacture CWDM 18ch with line monitor multiplexer,covers full range of ITU wavelength from 1270nm to 1610nm. By using reliable 8S0 filter(ie. 8 skip 0 filter) to achieve ultra low attenuation loss 3.5dB Max / 2.8 Typica.

 

In our 18ch CWDM multiplexer with 1% monitor, common IL on monitor port is less than 23dB,the 1% monitor port can work as network line monitoring or network power monitoring without disturbing current fiber link. Compare with standard 18CH CWDM multiplexers at 5.0dB attenuation loss,Arkoptics 18CH CWDM with monitor Mux Demux modules can achieve ultra low attenuation loss by 3.5dB Max / 2.8 Typical.This is a great optical performance in high speed WDM access network transmission,especially for 18ch CWDM access network over one pair fiber.

 

18ch CWDM with monitor, Mux and Demux build in one 1U 19” rackmount chassis,full range of ITU wavelength from 1270nm to 1610nm, with 20nm increments thus you don’t have to replacing or leasing additional fibers for current WDM network.Our 1U 19” Chassis will have clear channel port prints and Tx Rx indications for easy patching in datacenter. Customer logo can be printed on the front patch panel as well.At the meanwhile,we have mounting bracket on the chassis which can flexible to expand or reduce the mounting depth in datacenter cabinets.
