Subsea Cables & Internet Infrastructure

Layer 1 bandwidth is increasingly tight in the Pacific Triangle consisting of Tokyo, Hong Kong, and Singapore. In particular, many carriers' spare ADC capacity is completely gone. Whole fibre pairs are exhausted. Most older cables like SJC are maxed out. Even SJC2 is mostly gone. A large number of resellers is compounding the bandwidth misery by demanding 100G pricing in the $9K to $12K range. This is absurd and not happening. I know of 3x ADC 100G waves available on the Tokyo/Singapore route. One year contracts only. Non-Chinese carrier and equipment. Demarcation points are SG1 and Maruyama CLS. MRC is an inexpensive $13.7K. Don't be a fool and shop this price because this is the network operator's offer, not a resale by me. I don't resale. I take you to the Source (like the Machine Main Frame in the Matrix film series). There is one SJC2 100G wave available for contract early February. SG3/CC1. Available on a 3 year contract at $13.5K MRC plus a $10K install. One SJC...

Larger wavelengths reduce overhead loss and result in net usable bandwidth gains. Each 100G wavelength has approximately the same overhead loss as a 800G wavelength so bigger wavelengths reduce the ratio of overhead to data payload. Hence a fibre pair can gnerates more total payload transmission. Moreover, META avoids muxing and demuxing since many of their applications are 400G and 800G. Ciena, of course, wants to sell more expensive and profitable higher performance coherent and DWDM tech. I don't see this announcement as a remarkable breakthrough. It just reaffirms that the initial design capacity of 270 Tbps is achievable.
