Data Center Connection using ONS 15530

Hi!

1. I am connecting 2 Data Center using DWDM on ONS 15530. The client is GE and planning on running Gigabit Etherchannel.

2. My question is, whish one is better? Using the multirate transponder or GE aggregation card to connect to GE client?

3. Either way, how does client and ONS component interconnect?

- If transponder is used, how does the OADM, OSC, trunk card and transponder connect to each other?

- If muxponder is used, what component is needed ad how does it connect?

4. FYI, I come from ONS 15540 ESPx background where everything connect externally. Apreciate you guys expert response. Thanks.

Re: Data Center Connection using ONS 15530

You have three options:

1/ Use 8 port aggregation card (15530-FCGE-8P) together with 10G ITU card (4 port aggregation card is not cost effective if you are carrying only GE traffic). 10G ITU is the expensive part.

This 8 port aggregation module is connected to 10G ITU module via ONS15530 electrical backplane (not optical); 10G ITU and 8 port module both have 4x 2,5G backplane connections. 10G ITU is connected OADM using external MU-MU optical patch cords.

You can also use 2,5G ITU card but then you can only use 2 ports of the 8 port module card.

2/ Use 8 port multiservice muxponder (15530-MSMP-xxxx), this card has 2,5G capacity and card is SDH/SONET based. DWDM laser is embedded in the card, so this card is connected directly to OADM using external MU-MU optical patch cords (no backplane connections). Remember that this card is 2,5G so if you plan to use only GE you can utilize only 2 ports from the module.

3/ Use Transponders (15530-TSP1-XXX2) as you do in ONS15540. One Transponder - one client signal - one lambda. Transponder is connected directly to OADM using external MU-MU optical patch cords (no backplane connections).

-

What solution fits best for you depends on how many GE connections you need, what are future needs for more ports, what is your optical power budget, do you need high availability (no single point of failure) etc. Cheapest way to run only 2x GE is using option 2 above.

I think you can go for the GE aggregation card to connect to the GE client. This will give a better throughput compared to the multirate transponder.
