Optics and Optical Networking

guysdo i need X2-10G-ER or XNPEK if the distance between the 4 H.O range  between 11 and 15 and 20 KM,over songle mode fiberedo i need here DWDM or CWDM,if so why,plz explain?also pls expain if y chose X2 over XNPEK?Thanks

Hi,   I am looking for optics which can work for longer distances like 30-40kms using 1310 wavelength and we did see that there is a module for it ( GLC-EX-SDM= ). But I would like to know if I can use it in Cisco 3560 ? Do let me know what all switc...

I would like to know the difference between LX and LH SFP modules. Long Haul ( LH ) denotes longer distances while Long Wavelength ( LX ) denotes less energy which is obviously shorter distance. Why does Cisco use both LX and LH for certain SFP modul...

Can I connect the STM-1 interfaces of PA-MC-STM1 card to PA-STM1 card? If so what are the configurations I should do to connect them. I am having 7206 with cSTM-1 interface and another 7206 with STM-1 interface. Do suggest on the configurations if do...

Hi,I just need to know of GL-LH-SM can support distance over 550 m on multimode, i mean what will be the behaviorof the speed if the distance is over 550m, will it be 100MB instead of 1GB? if no is there any modulethat can go over 550m for 100MB on m...

Does anybody know if the eWDM (mux-8a) can work without the dWDM mux?

Hi all,I am planing to connect two sites using cisco dwdm, the distance between them is 50 km,i need 4 channels or 8 channels DWDM device.i was wondering if it's possible to do that using CWDM.any help please.Thanks

Hi,How to I configure ML-MR 10 card to monitor interface card using MRTG? Is there a way to setup the ONS to send the info from the card.Thanks,Dan

I have two cisco switches with 2 GBIC ports each. I want to link them with fiber.I have two ws-g5484 that was gave to me. What else do I need to link these switches?Do I need media converters and if so how many.Thank YouBo Hunter

We have just installed and provisioned a 15454 platform with the 15216 40 channel odd mux demux. Interestingly, setting the laser to 1556.15 corresponds to the 1556.5 channel on the mux. All of the channels on the mux appear to be even and off-by-one...

Does anyone have a handy (hopefuly updated) guide for which line cards and feature cards are available and in which slots they can be installed on a 14545 chassis?  I'm sure this information is lurking in a guide or manual, still hunting for it...Tha...

I have a 400 km long fiber optic network to design in order to connect two remote sites in the desert. The existing fiber optic cable between the two sites is ITU-T G.652 compliant single-mode fiber. Furthermore, there are stations along the 400 km s...
