Phạm vi áp dụng / Scope of standard

This American National Standard describes the physical interface
portions of a high performance serial link based on the work of the
XFP MSA. FC-PI-3 applies only to the variant described in FC-PI-3
and does not affect or supersede any requirements in any other FC
standard or technical report.

This specification defines the electrical interfaces called XFI+
based on INF-8077(XFI) the XFP MSA for high-speed serial operation
from 9.95-11.1 Gigabaud. This specification enhances the XFI
specification to achieve greater printed circuit board (PCB) trace
length and changes the return loss for the ASIC/SerDes to improve
manufacturability. The acronym XFI+ is used herein to describe this
interface. The XFI+ interface is defined to operate over 200-300 mm
of PCB traces that connect to an optical module or another device
with XFI+ interface. XFI+ is defined for 10GFC operating at 10.52
Gigabaud, however the same specification can support Datacom
applications (e.g.,10 Gb/s Ethernet) and Telecom e.g., (SONET
OC-192 and G.709 "OTU-2"). Nominal symbol rates include 9.95GBd,
10.31GBd, 10.52GBd, 10.70GBd, 11.09GBd (Ethernet plus FEC) and
11.31GBd (10GFC plus FEC). The modules support all data encoding
for these technologies. The modules may be used to implement single
mode or multi-mode serial optical interfaces at 850 nm, 1310 nm, or
1550 nm.

The FC-PI-3 specification includes the following
information:

a) XFP reference model and description

b) High-Speed Electrical Specification XFI+

c) Implementation and measurement suggestions.

1) Compliance Test Points and Boards (Normative)

2) XFI+ Channel Measurements and Modeling (Informative)

3) Differential S-Parameters and TDR (Informative)

4) Optimum Via Design

5) Jitter Methodology and Measurement (Normative)

FC-PI-3 is for a single electrical variant based on 64B/66B
coding in datacom applications, which is complementary to the
serial optical variants described in 10 GFC.
