Cisco XENPAK Transceivers - Refurbished, Used, New
Cisco XENPAK transceivers are 10 Gigabit Ethernet optics for switches and line cards with XENPAK ports, such as the Catalyst 6500 WS-X6704-10GE module. This page carries XENPAK SR, LR, ER+ and DWDM modules and a Catalyst 6500 4-port XENPAK line card, new, refurbished and used. Refurbished and used units are tested before they ship. A XENPAK module only fits a XENPAK port, so confirm the port type on your switch or line card first.

Which XENPAK do I need?
Choose by fiber type and distance. The SR module runs over multimode fiber in the data center or building, and its reach depends heavily on the grade of fiber. The LR and ER+ modules run over single-mode fiber for longer links between buildings or sites. The DWDM module carries 10 Gigabit Ethernet on a fixed ITU grid wavelength for use with a DWDM optical system; it must match the channel your DWDM system expects. Both ends of a link need matching optics.
Does the XENPAK-10GB-ER+ need an attenuator on short links?
Yes. Cisco's XENPAK data sheet says links shorter than 20 km need a 5 dB attenuator with the ER+ module, and links longer than 30 km are treated as engineered links.
Which patch cords do these modules use?
All of these modules use SC connectors. For the DWDM XENPAK, Cisco supports PC or UPC patch cords only, not APC.
Which chassis take the WS-X6704-10GE line card?
Cisco lists the WS-X6704-10GE for the Catalyst 6503-E, 6504-E, 6506, 6506-E, 6509, 6509-E and 6509-NEB-A, and slots 9 through 13 of the 6513, with a Supervisor Engine 720. Cisco also lists SR, LR, ER and DWDM XENPAK modules among the optics the card supports.
