This year, China's major operators have promised to build XXXX 5G base stations, which is a tense period of sudden construction by the end of the year.
5G base station, the optical module scheme of medium return transmission basically has no big objection. 5G forward transmission has become a very lively topic in this year's optical Expo. What scheme is used in the end,
Gray, bidi, color?
In color light, fixed wavelength or tunable
In fixed wavelength, 6 wave or 12 wave, CWDM, mwdm or lwdm? It's all a question.
The reason why we can't make up our mind is that the industrial chain is not mature, or it doesn't reach the maturity of the customers' mind of good quality and low price.
Our industrial companies have different positions of respect due to their own technical advantages and commercial interests. For example, those who sell optical fiber hope that operators can lay more optical fiber instead of color light.
Selling AWG, we hope to use more color light, so AWG will have a market.
Finisar's solution for 5G prequel is that customers can use whatever they say, because my family has it.
Gray light can support, so can color light
The fixed wavelength can support and the tunable wavelength colorless module can also support
In fixed wavelength, CWDM can support, lwdm can also support
Tunable colorless scheme, narrow-band tunable support, full band tunable now also can, o-band tunable scheme, C-band tunable scheme.
One sentence summary
... can well support all kind of.
