copper cables with connectors known as CX4. Transmission distances vary from 100 metres (330 ft) to 80 kilometres (50 mi) for fiber and up to 15 metres (49 ft) on CX4 cable. Newer XENPAKs using the 10GBase-LX4 standard operated using multiple wavelengths on legacy multi-mode fibers

The XENPAK form factor was initially supported by numerous network equipment manufacturers and module makers. However, advances in technology led to more compact form factors for 10 Gigabit
Ethernet applications. Soon after the standard was introduced in 2001, two related standards emerged:

The XENPAK MSA was publicly announced on March 12, 2001 and the first revision of the document was publicly released on May 7, 2001. The most recent revision of the MSA, Issue 3.0, was published on
September 18, 2002. The result covered all
64:. The MSA group received input from both transceiver and equipment manufacturers during the definition process. XENPAK has been replaced by more compact devices providing the same functionality.

Although the XENPAK agreement received early support, its modules were thought to be overly large for high-density applications. As of 2010, vendors generally changed to use

at distances of up to 300 metres (980 ft), eliminating the need to reinstall cable in a building when upgrading certain 1 Gbit/s circuits to 10 Gbit/s.

The X2 group was announced on July 22, 2002, and published their specification on
