Fairly standard, you get the copper or the SFP. Same with plenty of switches (eg, EX3200). > Has anyone used these...

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. -- Julien Goodwin Studio442 "Blue Sky Solutioneering" _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
