Optics and Optical Networking

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.

HiI need your help regarding the following : I have two ONS 15454 to be connected by a DWDM link. Each ONS has one Muxponder card and a OSC-CSM card without OADMs MUXs or DMUXs Or Amplifiers. Is it possible to make a direct connection between the Mux...

Has anyone attempted to run a BLSR with DCC's turned off? Need to segment a large subnet on a 454 network. If you can run a multi-vendor BLSR shouldn't you be able to run an all 454 BLSR with select DCC channels turned off to acheive network segmenta...

I've ordered 10 GLC-LH-SM=. I know, that on MMF Cable it runs up to 550m, with SMF up to 10km. ;-)I try to test to SFP but I couldn't see any link coming up either with SM neither with MM fibre cables. I also try on a working link, about 3km SMF, but...

I am looking for a AC/DC converter for a ONS15454 for a 220V input. The ONS 15454 datasheet indicate input current 22A maximum.The Cisco AC/DC Power Solution datasheet indicate for ONS 15454 a medium solution.And the same datasheet indicate the small...

We have multiple 2950's interconnected with ws-g5484's. We recieved some new 5484's with handles instead of the squeeze type and they are not recognized by the 2950's. Both types have the same 30-0759-01 part #'s and came from the same vendor.Any i...

Goodmorning to everyone.We need you help about the GLC-BX SFP compatibility with the Media ConverterAllied Telesis AT-MC1008/SP.In particular we want to try the Cisco GLC-BX with AT-MC1008/SP (1Gbps ethernet trasmission on one single fibre).Are there...

Hello,I am a Systems Engineer working with a Cisco Channel Partner.A client of ours has a fiber backbone between two buildings on their campus.The fiber terminates on a Catalyst 6509 (at the data centre) and a Catalyst 3750 at the other end. Users at...

What is the difference between the two units? When I spec out the SFP requirements, different switches use one or the other. The ME3400-24FS-A uses the GLC-FE-100FX and the 2960-24TC-L uses the GLC-FE-100FX=.
