Optics and Optical Networking

Hi Rather a broad title i know. I am primarily an IP person and now need to get up to speed on some of the optical technologies. I have done some reading around SONET, DWDM, Metro ethernet etc. but i am still struggling to understand a few basics i t...

Hi, I have purchased 1 3560 switch with SFP GLC-LH-SM, i have to connect it with C4506 with GBIC WS-G5486. Can i connect them via SM cable terminated at SPF side with LC connectors and at GBIC side with SC connector. Is this possible or i need s...

IOS c12kprp-k3p-mz.120-32.SY4.bin and c12k-fpd-pkg.120-32.SY4.pkg We have 2 Gigabit port SPA (SPA-2X1GE-V2=). It has both options SFP and RJ45. But when we change media-type rj45, the port doesn't come up until we insert Fiber module in the optical...

I am working on a Project to design a SONET NODE, the aim is to send Fiber to Home in a City. Questions? What SONET topologies are the best? What elements are included in a SONET NODE? Any block diagrams would help. Thanks

I have 2 ONS15454 connected as a ring. Previously, when I log in CTC it displays both nodes. But now when I login from any 1 of them, CTC only displays the directly logged in node and 2 DCC lines; the other displayed as Unknown#. I search docs and it...

We are looking into an application to allow transfer of a high rate synchronous data stream over a SONET network. We have a data stream (up to 2 Gbps) that we would like to format to fill out an OC-48 link. We are trying to determine if this is pos...

Looking for advice setting up two ONS boxes with two 15540-PWR-AC power supplies. The manuals/CCO show rack design for just the ONS boxes and a fuse/alarm panel. I have two side by side racks for the gear. Has anyone set up the power supplies for an ...

Can the Short-range STM64 optical card (15454E-10G-I1) supports the Intermediate-range XFP (ONS-XC-10G-I2)??? Anyone tried this configuration before? On the catalyst switches, the SFP linecards can support all types of SFP (SX, LX/LH or ZX). Can the ...

%SFP_BFRP-4-BAD_SFP : SFP error Duplicate SFP on port GigabitEthernet 2/1______________this caused other interface 1/1 down and resulted n/w failure...I guess its SFP duplication , but what exactly it has duplicated as both SFP are from Cisco..any fu...

Hi All, I am trying to understand the reason why the protect card/port shouldn't be in OOS(Out of service) to avoid any traffic loss even though the protect card is not switching traffic in ONS 15454 as stated below "When a protection switch moves t...

Board.I am trying to turn up an OC12 (non-concatenated) that is muxed from a OC48. The OC48 terminates on an ONS 15454 on both sides. From there we run SM fiber to Cisco 12000 series onto an SM OC12/SMT4 Line card on both sides too.My settings for th...

Does anyone know what is the distance limitation for the internal connections between the diferent cards of a 15454 MSTP? That is between Transponders, Add/Drop Cards, Amplifiers in the same node.
