(OIF) CEI PHY Interface Mode
Optical Internetworking Forum (OIF) CEI PHY interface mode is intended to support
two main protocols:
■ Common Electrical I/O (CEI-6G) protocol defined by the Optical Internetworking
Forum at data rates between 4.976 Gbps and 6.375 Gbps
■ Interlaken protocol at data rates between 3.125 Gbps and 6.375 Gbps
HardCopy IV GX transceivers support a data rate between 3.125 Gbps and 6.375 Gbps
in (OIF) CEI PHY interface mode.
Figure 1–146 shows (OIF) CEI PHY interface mode configurations supported in
HardCopy IV GX devices.
