Q&A

---------------------------------------------------------------------------------------------------

Q: What is the XENPAK transceiver?

 

A: A XENPAK is a 10G optical fiber transceiver which supports a variety of physical interfaces, including single mode fiber, multi mode fiber and CX4 Infiniband copper cables.

 

 

Q: What is the Multisource Agreement(MSA)?

 

A: The XENPAK standard is defined in the Multisource Agreement (MSA), which defines a fiber optic or copper transceiver ,odule conforming to the IEEE 802.3ae 10GbE (10 gigabit Ethernet) standard.

 

 

Q: What is the transmission distances of XENPAK transceiver?

 

A: XENPAK transmission distances range from 100 meters to 80 kilometers for fiber. xenpak transceiver support transmission distances of up to 15 metres on CX4 cable. Recently introduced XENPAK transceivers supporting the 10GBase-LX4 standard utilize multiple wavelengths on legacy multi mode fiber at distances of up to 300 metres.

 

This can eliminate the need to install new cabling in a building or facility when upgrading certain 1 Gbit/s circuits to 10 Gbit/s.
