Over 400M Ports Shipping Every Year! Focus on Optical Modules Shipped
1970 1980 1990 2000
1973 - Bob Metcalfe writes first memo about Ethernet at XEROX PARC
1975 – Patent filed for Ethernet by Bob Metcalfe, David Boggs, Chuck Thacker and Butler Lampson
1980 – “DIX” “Digital /Intel/Xerox” standard submitted with 48-bit Ethernet address
Hand drawn diagram of
Ethernet by Bob
Metcalfe – circa 1976
1985 – First Ethernet standard released as IEEE 802.3 CSMA/CD
1998 – Gigabit Ethernet (GbE) standard released as IEEE 802.3z
1995 – Fast Ethernet (100Mbps) standard released as IEEE 802.3u
Early NIC with COAX and RJ-45 support
1990 1995 2000
1x9 non-pluggable Module
1998 – Gigabit Interface Converter (GBIC) standard released
2 port GbE Switch Blade 4 port FDDI Switch Blade
Pre-1990 – FDDI Module
Sugar Cube Optics
2000 2005 2010
2001 – The SFP standard finalizes and quickly dominates GbE optic
300 pin MSA is the first 10GbE module deployed
XENPAK, X2 and XPAK are 2nd gen 10GbE modules
SFP+ released in 2009 with serial 10Gbps electrical interface and dominates 10GbE
All 10GbE modules interoperate at the optical interface
XFP released in 2006 with serial 10Gbps electrical interface
SFF – The non-pluggable cousin of SFP+
2010 2015 2020
CFP used for 40GBASE-FR to support 4:1 Gearbox and higher power than QSFP+
CEI-56G-VSR being standardized in OIF and could lead to 40GbE Serial interface to SFP+
QSFP+ is the dominant 40GbE module type
Will IEEE standardize 40GbE with a 40GbE Serial electrical interface?

2010 – 1st Gen 100GbE standard released with CAUI 10X10 Gb/s electrical interface
2015 – 2nd Gen 100GbE CAUI-4 standard released with 4X25Gb/s electrical interface to enable CFP2, CFP4 and QSFP28
CFP designed for 1st Gen 100GBASE-LR4 to support up to 24W
CXP used for 100GBASE-CR10 and 100GBASE-SR10
CFP4 (6W) and QSFP28 (3.5W) can only support CAUI-4
CFP2 module supports CAUI, CPPI and CAUI-4 up to 12W
