What is the meaning of the CS and EE abbreviations in these sentences?

I believe that CS stands for Computer Science, and EE stands for Electrical Engineering. What it means is that electrical engineering looks at the physical circuit properties, while computer science ...

Questions regarding incoming packets at optical splitter from optical line terminator (OLT)

Technically, there's no copying to the various strands. With PON, the splitter is a passive, unpowered unit that optically splits the downstream light into multiple, weaker rays. Each 1:2 split ...

Get the raw binary stream from an optical fiber

The optical signal is a binary stream. I assume you mean to diagnose the equivalent electrical signal. SFP transceivers are ignorant to the actual L1 protocol in use. Their main job is to convert an ...

Why do PON technologies use time-division multiplex instead of merging beams of different colors (WDM)?

It's absolutely technically feasible, but it's all about cost and budget. Wavelength-division multiplex in the upstream would be more expensive to deploy and maintain - if budget didn't matter you ...

GPON upstream frames capture

GPON is a a collective term for various technology including 1G Ethernet variants (1000BASE-PX10, 1000BASE-PX20) or 10G-EPON 10GBASE-P(X). However, most Ethernet equipment isn't compatible with -P. ...

Does a 1xN PON fiber splitter always "utilize" all N outputs?

The PLC splitter is a passive optical device, so there's no way to make it split less than it was designed for (other than to replace it). As far as I know there are PLC splitters with uneven ratios ...

Need an estimate of the max power density

I think you'd be better off assuming these are not plastic/polymer since yellow = single mode = long haul = glass. See Plastic optical fiber the IEEE has not yet passed any of the proposals into a ...

Need an estimate of the max power density

If the manufacturer claims 300 mW power output, then why would you think the power rating is not reasonable? Unlike the mass market for UTP cables, where you see all kinds of crap sold, optical ...
