Optics and Optical Networking

Hi  Anyone have the experience for ROADM network design by Cisco CTP. Can you share design guide for this network?

Hello everyone, is there cisco optical network certificate? 

I am looking for an optical product that will handle longer distance/fiber loss than 10GbitER/ZR SFP+ optics will handle but without the complexity and cost of DWDM equipment. Do you have any recommendations for a product such as perhaps a switch/bri...

I'm trying to connect a Nexus c93240yc-fx2 using the 10/25G-CSR-S sfp to a 3850 using the 10G-SR sfp. I can't get the link to come up no matter what speed settings I put on either side. When I use another 10G-SR on the Nexus side, the link comes up n...

I am lucky enough to have multiple instances of Cisco DNA center, we have elected to separate our regions (Canada to instance 1 and US to instance 2) I need to delete a WLAN controller from Instance 1 and add it to instance 2. Both devices are runnin...

Hi all,  New to forum. I have a question on SFPs. I'm looking for 1G SFPs that will go approx 110km between Cisco units. My understanding is that this is beyond the capability of ZX SFPs but i have seen there are EZX SFPs that go to 120km. Could anyo...

Without using a repeater what equipment would one use to establish a 10 Gbit link on distances longer than a 10GbitER (25 mile/40 Kilometer) or 10GBitZR (50 Mile/80 Kilometer) optic would allow?  Is there a cost effective solution to do this or would...

I didn't find compatable sfp module for WS-3850-12S in "Cisco Optics compatibility matrix" for operate in smf 100mb. Is there any sfp to use in smf 100mb for this switch?

Is the DC power consumption on a ONS M12 the same as a M15

Cisco 15454, SW Version: 10.301-015-D0217-SPA, 10x10G-LC card, automatically reset frequently, any one know the reason? Along with some conditions:  Equipment Squelched(SQUELCHED), Signal Loss on Data Interface(SIGLOSS), ODUk: PM Alarm Indication Sig...

Hi all, I am a newbie to the networking world and I was just wondering if someone can explain to me what the term BACKHAULING means. In layman terms please, I have also had a look at google images and this still confuses me. Thanks in advance
