Transceiver Diversification (Redundancy) Solutions Mesh Module

• Shuffle the (4) 10G channel of each QSFP input across (4) separate MTP ports

Trunk

All MTP outputs are comprised of a single channel from each of the four QSFPs on the input side

Each SFP is link to a single channel from each of the four input QSFPs. If all SFPs are used for switch uplinks, they are not tied to the same QSFP in the other switch.

How to Increase Data Rate?

• Data Centers (especially cloud) continue to drive a need for increased speed (e.g. 10G server connections will outpace 1G connections in 2015)

• Traditionally we’ve been able to increase the Bitrate (turn the light off and on more quickly) within a single channel with serial transmission (e.g. 1G to 10G)

Path to 400G Wavelength Division Multiplexing (WDM) Transmission

Tx Rx

Rx Tx

• WDM : A technology which multiplexes a number of optical signals onto a single optical fiber by using different wavelengths (colors) of laser light.

• Analogy : If people in cars are data packets, to increase throughput we add more people/car.

• Parallel Transmission : Data is simultaneously transmitted and received over multiple fibers.

• Analogy : If people in cars are data packets, to increase throughput we add more lanes on the highway ( people/car and speed stays the same)

• 40G solutions now have SM/MM with 2 & 8 fiber solutions • Similar solutions are currently in development phase for 100G • Roadmaps for 400G show a path to similar solutions (few speed bumps)

Takeaway: After much discussion with transceiver and switch vendors the foreseeable future (100/400G) is dominated with 2f and 8f solutions.

Typical Transceiver Cost Cycle

• Parallel uses existing cost reduced components for building next generation transceivers (flat price curve)

• Duplex requires new components (new lasers, advanced modulation, etc) in order to achieve new data rate (costly components until volume is reached and process optimized)

Takeaway: Early adopters plan for parallel solutions because they upgrade before the cost curve converges.

Fibre Channel Optical Transceiver Roadmap

Takeaway: Fibre Channel on the SAN side of the Data Center is following a similar path at 128GFC by using a SR4 communication with breakouts.

Example: Brocade recently released the “Windu” blade (FC16-64) which is a 16GFC linecard which uses 16 QSFP breakout ports to achieve 64 channels (4x16GFC engineered parallel)

Impact on Structured Cabling What do these Roadmaps mean?

• Solutions for the future include both duplex and parallel technologies – MTP based connectivity still needed to support all possibilities

• Technology deployment considerations impact structured cabling design – What technology deployment might be used in the future?

• True 40G link or 40G to 4x10G link • SR4 (Parallel Optics MM) • eSR4 (extended reach Parallel Optics MM) • WDM (Duplex)

• Is there existing cabling infrastructure going through a migration (brownfield) or is the installation a greenfield build?

Port Mapping Optimized Harness Mapping

Allows for 24, 32, 36, 48-port blades on large chassis switches to be cabled with 8f harnesses without having to deal with un-utilized fiber/connectors.

Note: Base-8 cabling eliminates the unutilized connectivity for all line card port counts.

Harness (hydra) assemblies are often used for high-density line cards. This does not breakout cleanly when line cards are not divisible by six (for

example 32-port) hence you are left with un-utilized connectors.
