Fairly standard, you get the copper or the SFP. Same with plenty of
switches (eg, EX3200).

I could *swear* I had some more details, but can't find anything. If you
trawl through the 10.2 release notes you get this:

2-Port 10-Gigabit Ethernet XPIM—The 2-Port 10-Gigabit Ethernet XPIM is
supported on SRX650 devices.

The 2-Port 10-Gigabit Ethernet XPIM provides a connection to high-speed
Ethernet networks through branch WAN service and allows carriers to
provide multiple levels of Ethernet service with a single connection
option for all service ranges. The 2-Port 10-Gigabit Ethernet XPIM is a
single-slot XPIM that can be installed only in the 20-gigabit GPIM slots
(slot 2 or 6) on the front panel of the SRX650 Services Gateway.

The 2-Port 10-Gigabit Ethernet XPIM contains two 10-Gigabit Ethernet
interfaces with both copper and small form-factor pluggable transceiver
(SFP) terminations, to support redundancy and enable the SRX650 Services
Gateway to be used as a pure security service device.

The following key features are supported on the 2-Port 10-Gigabit
Ethernet XPIM:
Online Insertion and Removal (OIR) capable.
Contains a total of four ports (two SFP+ and two 10GBASE-T). Only two of
the four ports can be active at any time; mix and match between the
copper and fiber types is supported.
...
Quad speed support for copper mode: 10GBASE-T IEEE 820.3an, 1000BASE-T
IEEE 802.3ab, 100BASE-T IEEE 802.3u, and 10BASE-T IEEE 802.3.
Standard quality-of-service (QoS) features.
User-configuration of fiber and copper ports:
When the interface is configured as a copper port, a typical Ethernet
configuration such as Autoneg is supported. Forced rate and link mode
are allowed. Four forced and Autoneg rates are provided: 10 gigabits, 1
gigabit, 100 Mbps, and 10 Mbps.

> Also, does anyone know why these modules are so damn expensive (about US$9000) where most Cisco 2 port SFP+ modules, Juniper EX3200/4200 and HP E2910al cards are all around the $1200-$1500 range.

If they're not shipping in quantity that alone could be enough, the 4SFP
/ 2SFP+ module for the EX4200 cost a customer nearly $5k each when first
available.

Then remember it's (essentially) a 2x10g module for a router that
doesn't just do ethernet (even if that's all anyone does use them for)
and so a lot of bits that are included as standard in ethernet-only gear
is on the module.
