Foundry Networks B10Gx2 2-port 10 Gigabit Ethernet XENPAK Base module
The 10-Gigabit Ethernet interfaces operate at full duplex. They use GBIC-like XENPAK Multisource Agreement (MSA) optics, which are hot-swappable, allowing you to change the optics without removing the module from the chassis.
The following XENPAK optics, which can be optionally purchased, are supported:
1310nm serial for single-mode fiber 1510nm serial for single-mode fiber For these optics, use the matching fiber type with an SC connector. For example, if you are using the 1310nm serial module for single-mode fiber, attach a 1310nm single-mode fiber cable that has an SC connector.
