The general conundrum is, when should DWDM (aggregated wavelength division multiplexing transceivers) or other technologies be applied to increase the volume of shipments per fiber line, rather than continuously increasing the total number of fiber lines? At present, nearly 10 kilometers of large data center interconnection uses CWDM (Coarse Wavelength Division Multiplexing) 1310nm transceivers, which are not matched with the 1550nm transmission optical wavelength of DWDM system software. Therefore, high-core-count optical cables are used in large data centers for large-scale interconnection. Can the discarded fiber optic cable be picked up and used?
The next challenge is when to replace 1310nm transceivers with pluggable DWDM transceivers in access switches based on the addition of a multiplexer module? The reference answer is, when will DWDM become the best way to develop this kind of economy for the interconnection of the big data center in the industrial park.
In order to measure the feasibility analysis of this kind of transformation, one must check the price of DWDM transceiver and compare it with the current transceiver. The price model of the application scenario for all external chains is divided at this stage. In the foreseeable future, the connection of the colorful 1310nm system architecture of the application scenario fiber optic cable will once again occupy the advantage of low cost. The PSM4 (8-core fiber optic cable) replacement plan has proven cost-effective for applications below 2 kilometers, which are additional elements to increase the total number of fiber optic cables.

How to choose the right fiber optic cable?
Now that the requirements for an extreme, relatively dense internet have been established, it is critical to understand the best way to build such an internet. This kind of Internet clearly presents new challenges at the level of routing and hardware configuration. For example, the use of loose waterproof casing optical cable and single-core optical fiber fusion splicing is not scalable or feasible. If the 1728-core fiber optic cable is installed using the loose waterproof casing design, assuming 4 minutes per connector, the fusion time will exceed 150 hours. If equipped with ribbon cable, the welding time will drop to below 20 hours. Although 20 hours is still a lot of time for fusion splicing, it saves a lot of time compared to single-core fiber optic cable types.

At the same time, traditional fiber optic cable design concepts also face great challenges when installed in common 2 or 4 foot pipes. New fiber optic cable and ribbon design concepts have already hit the market, with mostly twice the volume of fiber optic lines in the same cross-sectional area. This kind of product is generally divided into two design concepts: this method uses a standard vector tape with more inseparable and encapsulated sub-modules, and this method uses a standard cable design concept with a management center or slot core design concept, with a Loosely fused web design bands that overlap each other.
Different ribbon cable designs are suitable for extreme relative density applications.
Using this new fiber optic cable design concept, it is possible to maintain a higher relative density of fiber optic lines in the same indoor space of the pipeline. How to use different types of new fiber optic cables with extreme relative densities, so that Internet users can maintain the relative density of fiber optic cables required for the interconnection of super-large-scale large data centers.
