Top of Mind Issues

ScalabilityThe solution that works for small installs can grow into and work for large systems

ModularityEverything works together All product line features and accessories are interoperable

DensityNeed more connectivity in the same spaceHigher port count / higher port density

PerformanceHigher bandwidth, higher-speed connectivity More compute power in the same real estate

AgilitySpeed to deploy Installer productivity Efficient maintenance

Risk mitigationRedundancy in design and in connection schemes

Ethernet Data Rate Evolution

More traffic converges onto single circuits Each circuit becomes more mission critical.

• Next Generation 100Gb/s Optical Ethernet Study Group

• New work impacts direction of future 100G MM PMDs

• 4x25G instead of (10x10G)

• Good for customers – reuse 40G cable plant

• Research focused on direct modulation of VCSEL @ >25 G

• 100G SR4 will use 8 lanes (4 Tx/4 Rx), QSFP MSA & MPO

• Preserves SR4 installations with OMx ribbon cable plant

• OIF group is developing CEI-28G-VSR common electrical interfaces for ANSI, IBTA & IEEE

• Fiber will have to be EXCELLENT to support upcoming 25Gb/s

Case Study: Migration Strategy

Critical items to note for MPO 10/40/100Gbe Migrations

• Gender• Polarity• Key

MPO Polarity Features & Types

Ex. Key – Up

Method A: Key-Up (female) to Key-Down (female)

Fiber Array

Connector Ferrule(Contains Fiber)

Outer Housing Alignment Pins (2)(Yes/No) for Male & Female

Polarization Key

Connector Body

Some Graphical Depiction of Types (Methods):

Method B: Key-Up (female) to Key-Up (female)

Polarity

• Transmit lanes of one module connect with receive lanes of other module

• Simple direct connection– Female MTP patch cord with “keys up” at both ends

• Not as simple in real life deployment when reusing MTP trunks– Method A Key up to key down– Method B Key up to key up– Method C Pair-wise flip

What is the Problem?Seems easy until Polarity & Gender are considered.

What’s New & Looking Ahead

SM

Signature Core™ – Next Gen Multimode

• Highest possible performance– exceeding all other distance (550m) claims with low

connectivity loss (typ. 0.25dB)– The only multimode fiber to correct for modal and chromatic

dispersion– Chromatic dispersion the limiting factor on performance for

links >8Gbps

• Benefits of deploying Signature Core™– Reduces capital expenditures

• Use multimode optical modules rather than single mode• Savings thousands of $ per link

– Flexibility – DC layout may depend on the length of the fiber optic links

– Performance certainty for 40G/100G Ethernet and 16G/32G Fiber Channel
