Objectives: Support 10Mb/s operation in automotive & industrial
environments over single balanced twisted-pair cabling Support for optional auto-negotiation over single-pair
Link Segment: up to 4 connectors for up to at least 15m
Define link segment & PHY to support point-to-point operation with 10 inline connectors using balanced cabling (1-pair) for up to at least 1km
Two amendments published already 802.3bw-2015: Amendment 1: 100Mb/s over single TP cable 802.3bp-2016: Amendment 4: 1Gb/s over single TP cable
IEEE 802.3cg 10Mb/s Single Twisted Pair Ethernet
9
Why is TIA looking at this?
IEEE 802.3cg 10Mb/s Single Twisted Pair Ethernet
Baseline frequency range from 100 kHz to 20 MHz may consider additional link segment specifications as this progresses.
IEEE P802.3cg Task Force is actively considering proposals for
different link segments Benefits offered by generic cabling infrastructure in supporting other
applications IEEE supportive of this concept inside buildings
Fibre Channel
Standardized by International Committee for Information Technology Standards, or
INCITS, T11 Technical Committee
10
Fibre Channel
FC 32G PI-6 / FC 128G PI-6P completed (bit rate 28.05Gbps)
FC 64G per fiber PI-7 & FC 256G PI-7P (bit rate 56.1 Gbps per fiber) Still facing several challenges for 64G FC using PAM-4
using work from IEEE 802.3bs Clause 121 (closely related 50GBASE-SR and 64GFC MM variants)
Wideband Multimode Fiber (WBMMF)/OM5 Fibre Channel Looks like this will be a transceiver media option for PI-7 (use two or four
wavelengths for 64G/256G variants)
Requirements for Link Speed Negotiation for transceiver modules (backwards compatibility to 32G) in development, including transmitter training for FC-PI-7 and new requirements for LSN for SFP & QSFP modules –
Breakout use cases will not be documented in std. (but could be implemented by vendors)
Possibility of draft publication by June 2018
