X2 transceiver is the 10G fiber transceiver, its development was based on former XENPAK standards, X2 10Gb transceiver inner function is almost similar with XENPAK, and X2 also can use one transceiver to fulfill all 10G Ethernet optical port function. X2 transceiver is about half size of XENPAK, this enable it suit for density installations.
X2 transceiver is a hot pluggable in the Z-direction module that is usable in typical router line card applications, Storage, IP network and LAN and compliant to X2 MSA.10GBase-SR X2 is high performance, cost effective X2 transceiver like SFP plus module supporting 300M transmission distance in the 10GBASE-SR/SW Ethernet, also, it is a fully integrated 10.3Gbit/s optical transceiver module that consists of a 10.3Gbit/s optical transmitter and receiver, XAUI interface, Mux and Demux with clock and data recovery(CDR). This 10GBase-SR version of X2 transceiver line uses an 850nm Vcsel Laser Diode to achieve 300m over 50/125 multi-mode fiber as 10GBASE-SR of the IEEE 802.3ae like the XENPAK 10G SR, it is Full duplex transmission mode, management and control via MDIO, also DOM(Digital Optics Monitoring) Support inside. The operating case temperature is 0 to 70°C as usual as the normal SFP transceiver. Sure it is RoHS 6/6 compliant and compliant with product safety standards.
FiberStore can provide 10G XFP, 10G BIDI XFP, CWDM XFP, DWDM XFP with competitive price and high quality, which are fully compatible with equipment from other suppliers such as Cisco , Juniper and so on.
