Hi all,

We are looking at doing a small FTTP deployment in a community of about 30
homes and I'm searching for options regarding access layer hardware.

Initially we thought of a simple point-to-point ethernet setup with
1000Base-BX to each premises and a 48-port access switch. However, finding
an appropriate piece of hardware has proven challenging because of our
requirement of a 60+ degrees Celcius operating temperature (due to outdoor
cabinet placement).

The only one I found that meets the temperature requirement was Cisco's ME
2600X with 44 SFP ports, 4 SFP+ and 65degC max, but it's a bit pricey for
our liking. Other offerings from HP (5800-24G-SFP), Juniper (EX4550),
Brocade (CES-2048F) were nice, but all only had 40-45degC max operating
temp.

I'm interested to see what other people are doing for these types of small
setups. Does anyone know of any other reasonably priced access switches,
32+ SFP ports, and able to withstand 60degC or higher operating
temperature?

We are also considering GPON, but given that we would only need one
interface for such a small deployment, most of the hardware out there seems
like overkill. Are there good small OLTs?


For your particular case, you might want to look at industrial ethernet
switches with IP67 enclosure specs.

From Cisco you can look at IE3000 series. They can do VLANs, routing, have
SFP ports for uplinks.

Another option would be the OCTOPUS series from Belden, they claim -40C to
+70C degrees operating temperature.

Eugeniu
