Project 2118 - Information
technology - Fibre Channel - Physical Interfaces - 5 (FC-PI-5)
The FC-PI-5 standard will define the requirements for new physical layer
variants that operate at higher data rates than those specified in FC-PI-4.
It is desirable that some of those new variants operate at distances the
same as or greater than those of the corresponding variants specified in
FC-PI-4.
The FC-PI-5 standard will consider all aspects of transmit, receive and cableplant
performance requirements for optical and electrical links. The standard will
enable interoperability of transmitter devices, receiver devices, interconnects,
and components among different manufacturers.
It is desirable that new variants in this standard be specified such that
they can be implemented with components that also support the legacy variants
defined in
the, FC-PI-4 standard.
Additional sub-projects may be proposed within the scope of this project.
Each will include appropriate signal specifications as well as information
about the
methodologies required to measure those signals.
The proposed standard will include physical layer variants from previous
standards to optimize consistency of specification methodology for all variants.
It
will include new variants to support a 1600 MB/s data rate. It will include
those variants specified in FC-PI-4 that are appropriate for new designs.
It will include clarifications and improved testing procedures for FC-PI-4
variants as required by the expanding body of experience in implementation
and testing. FC-PI-5 is not intended to serve as a complete replacement for
FC-PI-4. This proposed standard is not intended to address areas above the
physical level.
