  • We will cover OM1-OM4 multimode cables, and introduce the new OM5 cable for 100-400G. Understand cable connectors used in LAN and today's Data Centers. Build a modern transceiver, and learn about SerDez and the critical ASIC chips that drive higher speeds in the Data Center.
    A critical view of the cost/benefits of transceiver options. Look at the MPO/MTP connectors and how they transform fiber density.

  • @N1FNE
    @N1FNE 2 роки тому +2

    Overall this is a really informative video. Great for getting someone up to speed with fiber. One thing though, there is a difference between path loss and return loss. Path loss (including intrinsic losses) is the attenuation of the signal down the path between the transmitter and receiver. Return loss is the value of how much light is reflected back to the source. They are very different things. Great work. I look forward to watching more of your videos.

    I'm going to say what most of the comments are saying. I've learned more in this video than I have researching google and blog posts for years. Fiber is one of those dark arts because of all the different types. But this video put it in a super easy format and explained everything. All in 30 minutes. Thank you.

    I work for a major logistics company for Google. I see fiber cables, optical modules, network switches, etc. all day long. It was only after watching this video did I even begin to understand what this material was, how it is implemented, and what I had to understand if I wanted to work in the nearby Google data center. Thank you!

    Small correction: a plenum is an air _circulation_ space. If air doesn't normally flow through it, it's not a plenum. The drop ceiling in most commercial structures is a plenum as it's the return path for HVAC systems. In residential settings, most setups have ducted returns. (In my parents house, the space under the stairs is a plenum as the return duct is open to the back of the stairs, vs. ducts run all the way to the registers. In my house, there are two large ducts leading to filtered registers, one in a wall, the other in a ceiling.)
    Note: I had this very conversation with engineers, architects, and city inspectors w.r.t. a computer room ("data center"). We had to have revised plans _explicitly_ stating the area above the ceiling was NOT a plenum. Yes, HVAC ducts pass through the space, but there is no air moving in the space; the room is otherwise vapor sealed. (this was but one of the many nits picked with the city.)

      actually you would be well advised to use OS2 single mode cabling. That will allow you to move the signal from your FTTH connection to anywhere in the house and the extra cost of transceivers is trivial. Also OS2 is now cheaper than OM cabling of any grade.
      That said, cat 6a is fine for housing. Just put in empty tubing so you can pull the fiber cable if you should ever need to do so.

    @KarlKornel 3 роки тому +1

    Regarding 40 Gigabit in the chart at 5:03, there is one additional option, beyond the singlemode and MTP/MPO options: 40GBASE-SR-BD (or 40GBASE-SR-BiDi, short for Bi-Directional) uses the same kind of two-strand multimode cable used with 10GBASE-SR, but gives you 40 Gigabit Ethernet.
    With 40GBASE-SR4, you have an MTP/MPO-12 connector carrying 8 10Gbps wavelengths (four in each direction). With the 40GBASE-SR-BD, the transceiver combines the 10Gbps "lanes" into two 20Gbps lanes, sending each out over the two fiber strands. That's where the bi-directional part comes in: In each strand, you have 20Gbps wavelengths traveling in each direction.
    Although the length limitations for 40GBASE-SR-BD are lower than those of 10GBASE-SR, this is a great way to upgrade from 10 Gigabit to 40 Gigabit without needing to replace fiber. That's probably why, if you order a 40GBASE-SR-BD transceiver today, it'll take several months to arrive!
    See more details at community.fs.com/blog/bi-directional-qsfp-40gbe-over-lc-duplex-multimode-fiber.html

      I will consider the video, many cable companies are using fiber on the back end already and only use coax to the home. Thanks for watching!
