Hi , just a thought for Normis etc . Any way we can get a tandem tray for the CRS305-1G-4S+IN or CRS112-8P-4S-IN so we can put multiple devices side by side in a 1U slot ? Sort of like what Juniper,Dell and Netgear have with their switches ?
The multiple DC in jacks and ethernet management on the port make it ideal for small IDF pops where we run a a Wireless Wire/Airfiber/MetroLinq links between A-B or Colo space where we have to pay per U of rackspace.
Currently using CCRs and CRS112's with L2 Transparent Simple Queues for this but it's such a big waste dedicating a full 1U to 3 Connections.It's a very side use case this but I think it can be done more space efficient and cost efficient.

Pardon the terrible diagram.

i would love to have a future tandem-tray capable RB4011 or CCR router

Unfortunately RB4011 seems to be just a few mm wider than half of 19" net width ... so it's not possible to mount two side-by-side inside standard 19" rack. For that, single device would have to be max 200 mm wide to allow some space for mounting frame.
