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=.

To meet EMI compliance, version -02 or above of SR, LR, ER, LX4, CX4 X2 optics are required for WS-
X6708-10G-3C and WS-X6708-10G-3CXL, and version -02 or above of SR and CX4, version -03 or above of
ER, version -04 or above of LR and LX4 X2 optics are required for WS-X6716-10G-3C and WS-X6716-10G-
3CXL. This restriction does not apply to LRM. See release notes or external Q&A for more details.

Any passive mux demux can be used with the DWDM XENPAKs. The ONS 15216 Flexlayer filters are one of
the options.
