40GE & 100GE Status
1. 2006 IEEE formed HSSG 2. Jan 2008 IEEE 802.3ba 40Gbps & 100Gbps Ethernet Task Force. 3. ITU SG15. Transport focused. OTN Mappings of 40GE & 100GE. New OTU4 for 100GE. One WDMPHY (no 10GE LAN/WAN PHY issue). One FEC. 4. Optical Interworking Forum (OIF):...
From NIC to Lan On Motherboard (LOM)
1. LOM removes the cost barrier to adopt 10G On servers. 2. Server vendors require LOM to be backward compa>ble,hence LOMs should support: Interoperate with 100/1000/10000 switches Support RJ45 cabling infrastructure 3. 10GBASE–‐T meets these requirements and is the PHY of choice for 10G LOM ENPAK DWDM transceiver
Two Visions of the Future
1. If 10GE is not redefined and remains uneconomical at 300 meters, then 40GE solutions will be considered high value and can cannibalize the 10GE market. 40GE will fill the bandwidth gap in large data centers and drive bandwidth to the 100GE core. 2. If...
Why 40GE?
•Because it is here at the physical layer and can be here sooner than 100G •Because it fits the needs of the customer better than a 10X jump – Most cost conscience customers can’t afford to come to these meetings and ask for 40GE! •...
Alcatel-Lucent Building Colombia’s Network
PARIS — Alcatel-Lucent (Euronext Paris and NYSE: ALU) has been selected by Azteca Comunicaciones Colombia, a leading communications services provider in Colombia, as a major supplier for the deployment of a nationwide broadband network that will connect 753 municipalities across the country. This network will...
What is the relative time to market?
• Sooner than 100GE because of the physical layer – 40 Gig OC-192 PHY available today – 40 Gig QSFPs coming this year for multimode applications – 40 Gig QSFP short reach (2km) singlemode possibly in 2008 – 4X10 Gig X40s for multimode and singlemode...
Mind the MAC GAP (Between 1GE and 100GE)
• We need a 40G MAC/Ethernet to reach a larger market that is underserved by expensive 10GE products and overserved by 100GE products. – Factors of 10 jumps do not fit as many applications as incremental changes • One Size Fits All – fits very...
Don’t want to double the R&D effort
•Optimizing R&D effort is definitely a good thing – Did we learn anything from 10GE? • Should we have a transceiver MSA before the standard is complete? • Are the components cost-effective and manufacturable? – 40GE doesn’t need to double R&D Effort but new chips...
Must not delay 100G
If we continue talking about 40GE, it will delay 100 GE Agreeing to add 40GE instead of endlessly debating will lead to faster standards completion. The better question is will 40GE delay the standard significantly or even measurably. Sun showed that there is minimal effort...
