<![CDATA[SFP+ Module for 2100 and German ISP "GPON" Fiber]]>Hy. I am planing to setup a pfsense on a Netgate 2100 gateway.

My ("noobie") question now is... will the SFP+ Module work with my German ISP (Telekom), witch provides a "GPON" Fiber access. Can anybody tell me, when they have information on this, or how i can ask for compatibility?

It will appear as a 1000baseSX link whatever is connected to it:

[admin@2100-2.stevew.lan]/root: ifconfig -vvm mvneta0
mvneta0: flags=8a43<UP,BROADCAST,RUNNING,ALLMULTI,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=800bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,LINKSTATE>
	capabilities=804bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,LRO,LINKSTATE>
	ether 00:e0:ed:b6:13:59
	inet6 fe80::2e0:edff:feb6:1359%mvneta0 prefixlen 64 scopeid 0x1
	inet 172.21.16.220 netmask 0xffffff00 broadcast 172.21.16.255
	media: Ethernet autoselect (1000baseSX <full-duplex>)
	status: active
	supported media:
		media autoselect
		media 1000baseSX mediaopt full-duplex
		media 1000baseSX
		media 1000baseT mediaopt full-duplex,master
		media 1000baseT mediaopt full-duplex
		media 1000baseT mediaopt master
		media 1000baseT
		media 100baseTX mediaopt full-duplex
		media 100baseTX
		media 10baseT/UTP mediaopt full-duplex
		media 10baseT/UTP
		media none
	nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>

So it will either work or not with no real options tweak if it doesn't.

The answer depends a lot on the hardware involved but without testing a specific SFP module in a specific card on that specific provider it's difficult to answer with any certainty.
