Regarding the Views Expressed
My Industry Involvement– Chairman, Ethernet Alliance Board of Directors– Chair, IEEE P802.3bs 400GbE Task Force – Recording Secretary, IEEE 802 Executive Committee
The views I am expressing on IEEE standards and related products should NOT be considered the position, explanation, or interpretation of the Ethernet Alliance.
Per IEEE-SA Standards Board Bylaws, Dec 2013
“At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position of IEEE.”

Why 2.5G / 5G BASE-T?
• From 2003 to 2014 about 70 billion meters of Cat 5e and Cat 6 cabling were sold….
• The introduction of 802.11ac for wireless access points and > GbE needs
• 90% of ports outlets (≈1.3 B) are Cat 5e or Cat 6
• Customers want more value from this infrastructure.

Key Decisions
• Architecture– CDMII & Extender Sublayer– KP4 FEC (embedded in PCS)– Optional EEE Support– Appropriate OTN Support – Better future proofing
• Chip-to-chip (C2C) and C2M electrical interfaces– 16 x 25Gb/s (NRZ, based on
802.3bm)– 8x 50 Gb/s (PAM-4)
• 100m MMF (16 x 25G, NRZ – 16 parallel fibers, based on 802.3bm)

Trend #1: “Chip-to-Module”(C2M) Interfaces
• 10GbE interfaces not defined by IEEE 802.3
• IEEE 802.3ba 40GbE and 100GbE C2M interfaces, based on 10Gb/s
• IEEE 802.3bm 100GbE C2M, based on 25Gb/s
• IEEE 802.3bs 400GbE C2M, based on 25Gb/s and 50Gb/s

• Note 1 – 10GBASE-USR estimated to be no more than 10%. Counted as standardized 10G.
• Note 2 - 40GbE BiDi not included as “non-standardized”
