TIA-FAQ
• Can I use 568-C.0 for office-oriented building
networks?
• NO!
– 568-C.0 is the foundation for 568-C.1, but the
exceptions and allowances in 568-C.1 apply to
office-oriented networks
– Using 568-C.0 as the stand-alone standard when a
type of premise has a standard is not appropriate

Document Summary – 569-C (Pathways/Spaces)
•
569-C Default Ballot (5 items)
– Power separation and EMI/RFI debates continue
• Contributions Still coming in showing evidence of problems
• Language in documents
– NOTE – The diversity of services currently available, coupled with the continual addition of new
services, means that there may be cases where limitation to desired performance occur. When
applying specific application to the infrastructure described in this Standard, the user is
cautioned to consult application standards, regulations, equipment vendors, and system and
service suppliers for applicability, limitations, and ancillary requirements.
Document Summary – 569-C
(Pathways/Spaces)
• 569-C – Default Ballot (5 items)
– Table for power separation edited to more closely align with ISO
– Agreed to add a note
• NOTE – These guidelines should be considered for all applications.
Newer and , particularly, higher data rate applications (e.g.,
10Gb/s) may be more susceptible to EMI. Accordingly, extra
precautions or more conservative minimum separation distances
should be considered.
• Not without controversy
– Other comments adding 230 VAC power strips, commentary on cable
management and BAS
accepted
Document Summary – 606-B (Admin)
• 606-B – Industry Ballot
– Adopts identification scheme specified in 606-A
Addendum 1 for racks, cabinets, frames
– Creates new identification format for horizontal
links, backbone cables, campus backbone cables,
but allows old identifiers to continue being used.
– Creates new identifiers for telecommunications
outlets, equipment outlets, splices, etc.
Document Summary – 606-B (Admin)
• 606-B – Industry Ballot
– Adopts graphic symbol for identifying powered ports
– Introduces “Automated Infrastructure Management”
• The automated infrastructure management systems should be
capable of automatically documenting the infrastructure elements as
described in this standard, providing a comprehensive record of all
the connected equipment, facilitating easy trouble shooting,
providing and automated method of discovering and documenting
configuration of LAN and SAN switches and automatically discovering
and documenting end devices that connect to the network.
– Adding Symbols

IEEE 802.3 Projects
• 802.3az – Energy Efficient Ethernet
– Released for publication at February meeting
– Reduced power consumption during idle periods
• 802.3bg – 40GBASE-LR (serial 40G)
– No disapprove votes on first ballot
– Document will “fast-track” to publication
– Lower cost option than current 40GBASE-LR4
IEEE 802.3 Calls for Intrest
• Next Generation 100Gb/s Ethernet Interfaces for Optical Fiber
– To explore the market need and solutions to reduce the cost, power and
panel size of 100Gb/s optical interfaces that can be implemented with
the interfaces currently defined by IEEE Std 802.3ba-2010
• Extended EPON PMDs
– To explore the market demand, available technologies and definition of
optical interface parameters for higher power EPON PMDs, building on
top of IEEE Std 802.3ah and IEEE Std 802.3av, to address demand for
high power budget classes to address requirements for longer reach
and/or increased split ratio.
802.3ba
IEEE 802.3 Other Subjects
• Power Over Ethernet
– There is a collective effort to pursue a “POE++”
standard, but debates about the true demand
need to be addressed.
