Re: DWDM Mux/Demux using 40G Optics

[Faisal Imtiaz]

You can see the CWDM mux listed on their site, and they will also make custom 
mux for you. 

Let me know if you need a Sales Contact for them.. 

My last set of muxes from them were custom muxes and they were able to get me a 
configuration with a lower insertion loss than what is listed on their website. 
( I paid a small premium for that feature, which I was very happy to).

Hi,

Ex CubeOptics (now Huber Schuner) are just great. Been using them for years, 
rock solid. I highly recommend them.

Best regards.

Re: DWDM Mux/Demux using 40G Optics

[Colton Conor]

Besides FS.com and http://www.beetlefiberoptics.com, do you have any more
recommendations for passive muxes? I usually stick to and like FiberStore,
but I am wondering if there is anything out there better/cheaper.

One of the things I am noticing is the CWDM and DWDM SFP+ optics are quite
expensive at  $250 for CWDM and $350 for DWDM. I guess it shouldn't be
cheap to send 10G around a ring, but I am wondering what transponders cost.

Re: DWDM Mux/Demux using 40G Optics

[Jeroen Wunnink]

Another alternative is to ask the http://www.beetlefiberoptics.com guys.
They build muxes on spec and they can also provide a 1310nm wide-band port on 
their units which allows a 40/100G-LR4 aside from the 1550nm DWDM band. 

We’ve used some simple splitters (line/1310nm LR4/1550nm DWDM ports on a unit) 
and full passive DWDM muxes with a 40/100G-LR4 port on there and these work 
pretty good.

Re: DWDM Mux/Demux using 40G Optics

[Colton Conor]

Do you have any idea if fiberstore has one with both a monitor and 1310
wideband port? I would want both.

Seeing as how they don't charge extra for an expansion port, but do for
other special ports I am thinking of just using the expansion port.

Hmm.. not sure how you are reading this... 
I believe that there is no 'standard' and as such the actual filter on the 
mux/demux you are using may vary by mfg. 
I can confirm what is an expansion port... (pass everything thru that is not 
being filtered by the mux/demux ) 
I can also confirm that Fiberstore 1310nm port (not to be confused with the 
CWDM 1310 port) will pass all 4 wavelengths for 40g/100g optics. 
I don't have experience with the 1550nm port.

Correct that is what it is designed for. it allows a fraction of light (I 
am guessing would also cause an increase in insertion loss figure).

If you look at the OADM's e.g. like a Cisco CWDM OADM with monitor ports, you

Re: DWDM Mux/Demux using 40G Optics

[Colton Conor]

Luke,

I agree, I would be talking about getting one with the 1310NM special port
for the QSFP+ input that emitts 1270-1330nm light, and then say 4 client
ports on different channels than that light range.

RE: DWDM Mux/Demux using 40G Optics

[Luke Guillory]

If their 1310 passes them I would have to think you can't use is with other 
client ports that would fall within the window. Here is a graph showing those 4 
for the 40g it seems.

I guess that makes sense. The plus or minus some is the question. FS is 
claiming their 1310 port support QSFP+, which is 1270, 1290, 1310, and 1330 
combined. I understand you can us 1310, but I am still scratching my head as to

RE: DWDM Mux/Demux using 40G Optics

[Luke Guillory]

My understanding is that ports on the client side would have cut filters for 
that color, having 1310 and 1550 are nice since you can hang gear you already 
have off the mux for OOB and so on. I don’t think I have any CWDM with 
expansion ports to test with.


We use the following for simple testing, is it there and what’s the power.

Subject: Re: DWDM Mux/Demux using 40G Optics
I guess that is the real question. Besides the client ports that are clearly 
identified by channel number on Muxes, what channels can the special ports 
handle?
http://www.fs.com/products/43723.html It has 4 special service port options:

1. Expansion Port (Based on what I am seeing, I think this would be to stack 
another mux if you needed more channels. So I assume it allows all channels to 
be added besides the client channels?)

Exactly... this is basically a  pass thru port, i.e. what is not getting 
mux/demux should get passed thru (keep the insertion loss in mind).

2. Monitor Port (I think this is just a tap that you would hook a monitor up 
to, and be able to see all channels coming through with a meter. I assume not a 
good idea to add/drop channels through this port)?

I don't use this port, but supposedly it will pass a fraction 5%  of the light 
from the main port so that it can be monitored. May be someone else can offer 
some practical use for this port.
3. 1310nm Port (Labeled as 1310, but clearly allows more than just 1310 since 
tutorial is saying it supports QSFP+ which is 1270 - 1330 nm, so what range 
does it really support or is there no a range?)
Not sure about the range question, but this is the port for having the 40g/100g 
QSFP+ pass thru

4. 1550nm Port (Labeled as 1550nm, but I wonder if its like the 1330nm?)

I have not had the need to explore this in detail, but from my initial 
understanding, this can be used for ZR (long range optics) and or to stack a 
DWDM Mux

Would you recommend a monitor port on every mux you buy?

As I shared above, I don't.

Re: DWDM Mux/Demux using 40G Optics

[Mike Hammett]

I'd imagine they vary based on vendor, so you'd have to check with the specific 
vendor in terms of absolute technical specifications. 

A 1310 and 1550 port only allow those channels plus or minus some, manufacturer 
dependent. 
An expansion port passes everything not used by that device. 

Some manufacturers are even configurable pre-order, so you could get exactly 
what you needed (other than multiple 40G channels).

Thanks for the answers. From the sounds of it, no one knows the real difference

Subject: Re: DWDM Mux/Demux using 40G Optics

Let me try to explain better...

All Single Mode Fiber 40g Optics are using 4 cwdm channels ...

If you use a cwdm mux/demux with and expansion port and it is only 
mux/de-muxing 1450 to 1610  (i.e. not using the 1270-1330) you can use the 
expansion port to connect the 40g Optics

If you have a CWDM or DWDM Mux, with a specific 1310 pass thru port (Wide-band 
etc... check the specs) then you can plug the 40g Optics on to that port and it 
will pass the 4 channels thru it.

e.g. with the cwdm mux (see picture in previous post) ..you end up with  1x40g 
(lane) + 8 or 9 10g (cwdm lanes).

Re: DWDM Mux/Demux using 40G Optics

[Mike Hammett]

Verify the wavelengths passed by the 1310 port. Verify the wavelengths used by 
his existing 40G optic. Plug the 40G optic into the 1310 port.

Exactly... this is basically a pass thru port, i.e. what is not getting 
mux/demux should get passed thru (keep the insertion loss in mind).

I don't use this port, but supposedly it will pass a fraction 5% of the light 
from the main port so that it can be monitored. May be someone else can offer 
some practical use for this port. 

> 3. 1310nm Port (Labeled as 1310, but clearly allows more than just 1310 since

Not sure about the range question, but this is the port for having the 40g/100g 
QSFP+ pass thru 

> 4. 1550nm Port (Labeled as 1550nm, but I wonder if its like the 1330nm?)

I have not had the need to explore this in detail, but from my initial 
understanding, this can be used for ZR (long range optics) and or to stack a 
DWDM Mux

As I shared above, I don't.

Re: DWDM Mux/Demux using 40G Optics

[Colton Conor]

I guess that is the real question. Besides the client ports that are
clearly identified by channel number on Muxes, what channels can the
special ports handle?

http://www.fs.com/products/43723.html It has 4 special service port options:

1. Expansion Port (Based on what I am seeing, I think this would be to
stack another mux if you needed more channels. So I assume it allows all
channels to be added besides the client channels?)
2. Monitor Port (I think this is just a tap that you would hook a monitor
up to, and be able to see all channels coming through with a meter. I
assume not a good idea to add/drop channels through this port)?
3. 1310nm Port (Labeled as 1310, but clearly allows more than just 1310
since tutorial is saying it supports QSFP+ which is 1270 - 1330 nm, so what
range does it really support or is there no a range?)
4. 1550nm Port (Labeled as 1550nm, but I wonder if its like the 1330nm?)


Would you recommend a monitor port on every mux you buy?

Re: DWDM Mux/Demux using 40G Optics

[Mike Hammett]

Verify pass-through frequencies for the 1310 (or equivalent) for the passive 
mux in question. This would only work for a single channel.

If you look at the CWDM Muxes (8 or 9 channel) you will notice a common 
configuration of 

Upgrade Port (expansion port) + 1450 or 1470 to 1610nm 

in the DWDM muxes you will see them listed as # of Port + 1310 pass thru

RE: DWDM Mux/Demux using 40G Optics

[Luke Guillory]

The issue is that once you get above 10g things start to get expensive since 
you don't have options for straight 40g optics in different colors. At least 
not what I see, 4x10g like you have or a single 1310 40g with no way that I see 
to mux them. I guess the only way this might work would be to use optics that 
go from MTP to LCs for the 4x10 40s which you could then inject into a mux, for 
those colors along with a 1310 port for the other 40.

This is same thing you run into when talking 100g, active DWDM with 
transponders is how that's done with local gear SFPs being 850nm being fed into 
the DWDM gear for transport.

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/topics/reference/specifications/optical-interface-qfx-support.html

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.html

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?

YES this is correct and goes for pretty much all of the SMF QSFP+ 40g Optics. 
(they utilize 4 cwdm channels)

Typically you would stack 40G + 10g Channels or 100G+10g Channels
(100g optics would be using 4 channels as well).

Yep, that would be the cost effective way to do it.

Yes that would be correct, 1310nm is simple nomenclature when used with 
40g/100g QSFP+ SMF optics

If you  look at the CWDM Muxes (8 or 9 channel) you will notice a common 
configuration of

Upgrade Port (expansion port)  + 1450 or 1470 to 1610nm 

in the DWDM muxes you will see  them listed as # of Port + 1310 pass thru 
channel.

These are exactly what you are looking for . :)

Depending on switch vendor, it might be possible to create real 40GE interface
also from 4 consecutive 10G SFP+ ports. Then you can use standard 10G CWDM/DWDM
SFP+ optics and still benefit from wire-speed 40G uplinks.

Note that this is *not* etherchannel/LAG, but true HW-based 40GE mode.
