Pin Definitions

 

1) Ground connections are common for TX and RX.

 

2) All connector contacts are rated at 0.5A nominal.

 

3) 1.2V CMOS compatible.

 

4) MDIO and MDC timing must comply with IEEE802.3ae, Clause 45.3

 

5) XAUI output characteristics should comply with IEEE802.3ae Clause 47.

 

6) Transceivers will be MSA compliant when no signals are present on the vendor specific pins.

 

Q&A

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

Q: What is X2 transceiver?

 

A: X2 transceiver is the 10G fiber optic 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.

 

 

Q: What is the application of X2 Transceiver?

 

A: 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 XENPAK MSA.

 

The XENPAK transceiver 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).
