X2
An X2 Transceiver is a 10G fiber optic transceiver based on former Xenpak transceiver standards. The functionality of X2 and Xenpak transceivers is nearly identical, but an X2 Transceiver can also use one transceiver to fulfill all 10G Ethernet optical port functions. Physically, an X2 Transceiver is approximately 50% smaller than an equivalent Xenpak transceiver, which often makes the X2 a better choice for higher density applications.
All X2 Transceivers carried by SFPlus Transceiver conform to the IEEE 10Gbps Ethernet standard. All of our Cisco Compatible, 3rd party X2 transceiver products are also Multi Source Agreement (MSA) compliant, and will not void OEM warranty. The 10Gbps Ethernet standard is defined by the IEEE, and not only increases the data transmission rate, but also increases transmission distance over previous transceiver types. The IEEE 802.3ae 10G Ethernet standard defined the working distance from 300 meters to 40km. SFPlus Transceiver offers a variety of X2 fiber optic transceivers that are fully compatible with equipment from a variety of vendors including Cisco.
