Re: DWDM Mux/Demux using 40G Optics
by Tony Wicks 19 Jun '17

The guys at fibrestore will point you in the right direction on all this if you ask them these questions. They are actually very helpful and will assign you a specialist to assist. -------- Original message -------- From: Colton Conor <colton.conor(a)gmail.com> Date: 20/06/17 6:26 AM (GMT+12:00) To: NANOG <nanog(a)nanog.org> Subject: DWDM Mux/Demux using 40G Optics We are building a 40G metro ring using 40-Gigabit Ethernet QSFP+ Transceivers. Specifically, we are using Juniper JNP-QSFP-40G-LR4. This is a QSFP+ Transceiver with a LC duplex head. We only have one pair of single mode dark fibers around the ring. Our distance between nodes around the ring are all less than 10KM, so we can use standard optics. We go out of one JNP-QSFP-40G-LR4 and into another JNP-QSFP-40G-LR4. There are no passive muxes involved. This is working great for 40G. My understanding is a JNP-QSFP-40G-LR4 is really a transceiver with a CWDM mux built into it. The spec sheet shows it sends 4 10G channels: https://www.juniper.net/documentation/en_US/release-independent/junos/topic… Lane wavelength Lane 0–1264.5 nm through 1277.5 nm Lane 1–1284.5 nm through 1297.5 nm Lane 2–1304.5 nm through 1317.5 nm Lane 3–1324.5 nm through 1337.5 nm This setup is working fine, but now we want to do more than 40G around the ring. To my knowledge there are no other 40G QSFP+ transceivers that use four other channel/lanes than the ones already being used, so they only way to go higher than 40G is to stack 10G or 100G channels ontop of the fiber pair using a passive mux. 100G is too expensive for the time being, so we are looking to add 10G channels to a ring that already have one 40G channel using the QSFP+. I was reading this tutorial, and it mentions "there is a 1310 nm port integrated in a 40 channels DWDM Mux/Demux system. The 1310nm added port is a Wide Band Optic port (WBO) added to other specific DWDM wavelengths in a module. When we run out of all channels in a DWDM Mux/Demux system, we can add the extra optics via this 1310nm port." http://www.fs.com/upgrade-to-500g-with-40ch-dwdm-mux-demux-system-aid-493.h… What I can't seem to understand is they are mentioning that this 1310 port can pass QSFP+ signals, so it sounds like its really a 1270nm through 1330nm port? Is this what they mean by Wide Band Optic port (WBO)? We don't need 40 10G channels plus a 40G for a total of 440G. More than likely we are looking at a 8 channel mux/demux, and 1 40G port for a total of 120G. I don't care if we do CWDM vs DWDM, but I assume it will be hard to find a CWDM mux that has one LC dupluex input for 1270nm through 1330nm channels? Maybe I should just ditch the 40G QSFP+ optics and use all 10G optics, but the switches I am using have 48 10G SFP+ ports and 6 QSFP+ ports built in. I know there are 40G breakout cables, but the whole point of 40G is to aggregate VLAN/circuits. Has anyone done this before?

Internet connectivity in Nigeria
by Sina Owolabi 18 Jun '17

18 Jun '17

Hi All Currently having a terrible situation in Nigeria where the GLO1 and MainOne cables appear to be both down. Can anyone suggest a good Nigerian ISP with redundancies enough to overcome at least two of the following dying out? SAT-3 WACS GLO1 ACE MainOne Please dont say MTN or any of the Nigerian telcos, except there are no other options, customer service will leave you trying to commit bodily harm.

Net neutrality filing
by Stephen Satchell 18 Jun '17

18 Jun '17

> https://ecfsapi.fcc.gov/file/10616167661646/satchell.answers2questions.NPRM… Warning: this is 63 pages long, and dull as dishwater. It does have a few color pictures, though. And one comic strip. Summary: fix the statutes (thank you Sen. Stevens, for the junk!) and apply Title II only to monopoly Internet access service providers. I had sent this notice to a listserve (of which I'm a subscriber) of telecomm policy people, and I'm getting a whole lot of pushback. So I thought, why should NANOG lose out on the fun? So, instead of you hearing about this in the sweet bye and bye, I'll get the firestorm over with now, rather than stretching this out for three months. (I'm on this listserve, too.) And if you think my ideas are bad, perhaps you will propose a better suggestion to the FCC about the subject.

Re: Vendors spamming NANOG attendees
by Alexander Maassen 16 Jun '17

the discussion about the external spam kinda exceeds the volume of the spam itself. just my 2 cents. just block, delete, continue life Kind regards, Alexander Maassen - Technical Maintenance Engineer Parkstad Support BV- Maintainer DroneBL- Peplink Certified Engineer -------- Oorspronkelijk bericht --------Van: bzs(a)theworld.com Datum: 15-06-17 20:09 (GMT+01:00) Aan: Dan Hollis <goemon(a)sasami.anime.net> Cc: Niels Bakker <niels=nanog(a)bakker.net>, nanog(a)nanog.org, bzs(a)theworld.com Onderwerp: Re: Vendors spamming NANOG attendees On June 14, 2017 at 14:22 goemon(a)sasami.anime.net (Dan Hollis) wrote: > On Wed, 14 Jun 2017, bzs(a)theworld.com wrote: > > Merely deciding not to patronize them may not be sufficient and that's > > why we make that sort of thing just outright illegal rather than hope > > market forces will suffice. > > Most spam is sent from compromised machines anyway, so there are already > criminal violations involved in sending spam. FWIW I believe the context was a vendor spamming NANOG attendees (see the Subject:) so not likely being done from compromised machines. That said, yes, a lot of spam is sent from compromised machines as you say. But criminal violations can be additive, even rising to things like RICO charges (a pattern of organized criminal behavior etc.) which can be both criminal and civil and added onto charges like the criminality of specific mechanisms (compromised systems etc.) It really depends on how interested one can get the legal machinery in the problem. Thus far that's hit or miss. I can't find any instance where RICO charges were used against a spam gang tho, at least on a quick search. -- -Barry Shein Software Tool & Die | bzs(a)TheWorld.com | http://www.TheWorld.com Purveyors to the Trade | Voice: +1 617-STD-WRLD | 800-THE-WRLD The World: Since 1989 | A Public Information Utility | *oo*
