Questions & Answers
Q1: What OADM can we have?
(1) CWDM single fiber single-sided, East or West
(2) CWDM Single Fiber dual-sided OADM, East and West
(3) Dual Fiber single-sided OADM 1U Rack, East or West
(4) CWDM Dual Fiber dual-sided OADM 1U 19inch Rack, East and West
Q2: What we should know when choosing of the appropriate Wavelengths?
A2: A water peak in optical fiber attenuation in dB/km occurs at a narrow range of wavelengths within the telecommunication spectrum 1260 – 1625nm. For G.652 and G.694.2 optical fiber, the water peak occurs at 1383 ± 3nm, which means avoiding 1390nm and 1410nm wavelengths because of the higher attenuation.
Q3: What Connector can we choose?
A3: Various connectors are available - LC/SC/FC/ST, UPC/APC polish
Q4: How many channels are available for CWDM OADM?
A4: Following the standard ITU-T G694.2, CWDM OADM modules allow up to 18 individual wavelengths/channels separated by 20nm spacing from 1270nm to 1610nm. Any wavelength or wavelengths combination can be customized upon request.
