Only version -02 of these X2 optics is supported on WS-X6708-10G-3C and WS-X6708-10G-3CXL. See release notes or external Q&A for more details.

Besides CX4, all XENPAKs and X2s have dual SC (female) connectors. CX4 has an Infiniband 4x connector.

To calculate the exact distances that your module will support before installation, see optical specifications in the XENPAK and X2 data sheets.
The exact distance supported varies according to the number of splices and connectors in a single-mode fiber strand.

According to the IEEE 802.3ae standard, requires 5 dB 1550 nm fixed loss attenuator for <20 km; a 5 dB fixed loss attenuator is available as a spare,
part number WS-X6K-5DB-ATT=.
