VDX 40GB optics

Hi,

 

I would like to know: What is the max distance for coupling 2 x VDX over multi mode (OM4) using the 40GB ports ?

We have to connect to rooms. The people told us now the cable length would be ~200m, but the used multimode ...

 

So is there a chance to couple the VDX with 40GB ?

 

And what about our SAN ? Same problem ? What is the max. distance (8GB) ?

 

Bye, Peer

Peer,

see table below.

AFAIK, yes, you can use the 40 Gbps Port as ISL/Uplink Ports.

140 m link length on OM3 multi-mode fiber and 160m link length on OM4 multi-mode fiber
