The X2 transceiver module is a hot-swappable I/O device that plugs into Ethernet ports. The X2 transceiver module connects the electrical circuitry of the system with the optical or copper network.
XENPAK transceiver was the first MSA for 10GE and had the largest form factor. X2 transceiver was later competing standards with smaller form factors. X2 transceiver has not been as successful in the market as XENPAK. XFP came after X2 and it is also smaller.
The newest module standard is the enhanced small form-factor pluggable transceiver, generally called SFP+. Based on the small form-factor pluggable transceiver (SFP) and developed by the ANSI T11 fibre channel group, it is smaller still and lower power than XFP. SFP+ has become the most popular socket on 10GE systems. SFP+ modules do only optical to electrical conversion, no clock and data recovery, putting a higher burden on the host's channel equalization. SFP+ modules share a common physical form factor with legacy SFP Modules, allowing higher port density than XFP and the re-use of existing designs for 24 or 48 ports in a 19" rack width blade.
X2 transceiver uses XAUI to connect to their hosts. XAUI (XGXS) uses a four-lane data channel and is specified in IEEE 802.3 Clause 48. XFP modules use a XFI interface and SFP+ modules use an SFI interface. XFI and SFI use a single lane data channel and the 64b/66b encoding specified in IEEE 802.3 Clause 49.
The X2 transceiver are designed for Storage, IP network and LAN. It is a fully integrated 10.3 Gbps Optical Transceiver module that consists of a 1550nm wavelength optical transmitter and receiver. The X2 transceiver is a hot pluggable module in the Z-direction that is mainly usable in typical router/switch line card applications. In addition, they comply with the X2 Multi Sourcing Agreement (MSA). The X2 transceiver can achieve 80km over standard Single Mode Fiber.
