Low cost WDM gear

Sat Feb 7 19:04:10 UTC 2015

Hi Enviado,

I cannot recommend FiberStore as I had a bad experience with them.  I needed to cover only 3km from A to B side.  When using 10km optics, I saw a loss of over 5db  with their passive mux inserted into the path which created a total loss of over -20db which is outside of the tolerances for our equipment with 10km SFP+.  Using another vendors low insertion loss mux corrected our issue.  I am sure if you are using an 80km optic, you may be able to tolerate a higher insertion loss to cover < 60km.  I also notice that their CDWM optics averaged about 3db less in power output when compared to other vendors.

Thanks

Kenneth

Hi kenneth... which the distance do you have from side A to side B when you using passive solutions from fiberstore( mux and demux)?
I buy this mux and demux(4 channels single fiber) and only make a test about 60km( mux side A and demux on side B) with sfp+10gb for 80km... ( only see ddm on my ex3300( about -19db for 60km). Test switch access with ssh and pinging tests...
What kind os issue do you have? For distances less than 60km is this solution good?
Thanks!!!

Mike,
I just replaced a bunch of FiberStore WDM passive muxes with OSI Hardware equipment. The FiberStore gear was a huge disappointment (excessive loss, poor technical support, refusal to issue refund without threatening legal action, etc.). I have had good results from the OSI equipment so far. I run passive muxes for CWDM (8 - 16 channels).

Hi Mike
I can recommend a couple of vendors that provide cost effective solutions.
Ekinops & Packetlight.

I know there are various Asian vendors for low cost (less than $500) muxes
to throw 16 or however many colors onto a strand. However, they don't work
so well when you don't control the optics used on both sides (therefore
must use standard wavelengths), obviously only do a handful of channels and
have a distance limitation.
What solutions are out there that don't cost an arm and a leg?
