Optics and Optical Networking

We are attempting to create an STS-3c Ethernet circuit between 2 nodes that both have the E100T-12-G Ethernet cards on an OC-48 ring.  We know there is the limitation of 12 total STS's that can be created on each of the E100T cards.  Node A has (6) S...

Hi,I have 2960-48TC-S and GLC-SX-MM SFP module.I need to install the GLC-SX-MM in mentioned above switch and give connectivity to existing LAN switches like 3560, 2960 etc.What type of fiber cable is required for this connectivity. How to check that ...

Hi,  I read many market reports that talk about the revenues for SONET and WDM equipment - Can someone clarify the difference between these 2 terms.I assume that SONET -say OC48 or OC192 are transmitted through optical fibre and the optical technolog...

Hello everyone,I've got a problem with my ONS system. As you can see in the figure, the first one is CTC view of Node1 and the second one is Node2.In LINEAR model, side B of Node1 connect to side A of Node2. But take a look at them, side B of Node1 i...

Hi,I have cisco 4503 switch ... I want to terminate fiber connection from one of the local branch to this switch. cisco 4503 are having total 8 port with 1 gbi have S.T. connection which has come to local office and i would like to connect to 4503 sw...

Are mode conditioning cables required for switch to switch connection over multimode fiber (200Meters), if we are using fiber jumpers between device and fiber cable on both ends?Thanks,

Hi1)am still confused a bit about DWDM and CWDM,where and when we need such this technology?mean for customer requirments2)What is the benefits of Channels e.g up to 40 channels now?3)whose offere this services?its is offered by ISPs Goverments?Thank...

We are building a lab that needs to simulate our WAN. I would like to incude an 2 MSPP routers but the Cisco ONS 15454 SONET Multiservice Provisioning Platform (MSPP) is cost prohibitive. It is what we use so it is the only MSSP I know of. Is there ...

Are there any SFP+ Transceviers that can be removed from the switch/device without first requiring the disconnection of the optical cable or copper cable?

I have a 3560g switch. Have gig sfp interface [GLC-SX-MM=] and want to connect to to WS-2924C-XL f0/24 fasteth fiber port.I have a patch panel in the middle.3560g sfp interface [GLC-SX-MM=]   SC   ---------- ST PP  ST   -------------------------   SC...

Hello!Two 3560Es connected.There was a 6 sec outage of TenGig interface 0/1 on switchA, while no error messages and interface outage were fixed on switchB.What are the possible reasons for that outage (perhaps fiber/optical connectors raw movement) ?...

I have some Catalyst 3560 switches that I need to connect over a long distance. The existing backbone is 62.5 850nm multimode and unfortunately I dont have the option of installing single mode fiber at this point. The distances range from 2000' to 60...
