This document provides a technical overview of Cisco's MultiGigabit Ethernet technology. It discusses how existing Gigabit Ethernet infrastructure is insufficient to support wireless speeds beyond 1 Gbps. Cisco's MultiGigabit technology allows speeds of 2.5 Gbps and 5 Gbps over existing Cat5e cabling without replacing the infrastructure. It also details Cisco's MultiGigabit product family including line cards, switches, and supported speeds.
3. The Problem - Gigabit Bottleneck
Existing Gigabit infrastructure
is insufficient to handle .11ac
growth beyond 1Gbps
Gigabit Ethernet has been
around since 1999 and has
now become the bottleneck
Market needs an innovative
technology to support >1Gbps
over existing cables
Limited to 1G!
Cat 5e Cables
WiFi @ 1G>1G
4. Why Not Use 10GBASE-T?
UTP Cable IEEE 10G Spec
CAT 5/5e N/A
CAT 6 55 meters
CAT 6A 100 meters
CAT 7 100 meters
>75% of WW installed base is Cat
5e/6 up to 100 meters
10GBASE-T cannot work over vast
majority of installed base

Cat 5e – 38%
Cat 6 – 53%
Cat 6A – 8%
Cat 7 – 1%

upgrade involves
• New cable runs,
including labor: average
$300 per cable
• Link Aggregation issues

The Non-MultiGigabit Ports Are the Same as Previous
Line Cards / Products – Support 10M/100M/1Gig Speeds

Auto-negotiable Speeds – Interoperates with
legacy ports at 100 Mbps and higher
Brownfield Deployments can leverage existing
Cat5e cables, extending ROI, and supporting
speeds at 2.5G and 5G at a Distance of 100m
Greenfield Deployments with Cat6a Will
Support 10G – They can also support speeds at
2.5G and 5G at a distance of 100m
