INTRA DATA CENTER OPTICAL INTERCONNECTS
• OPEN STANDARDS • COST-EFFECTIVE • THIRD PARTY OPTICS FOR LAYER 2 AND LAYER 3 CLIENT EQUIPMENT
• SMF OPTICS: INTER CAGE • MMF OPTICS: INTRA CAGE (INTER SWITCH TRUNKS) • 10G-BASE-LR, 40G-BASE-LR4, AND 100G-BASE-LR4 • HIGHER DENSE QSFP+ (40G) AND QSFP28 (100G) • 400GE AND 1 TBE INTERCONNECTS IN 2018+
Requirements

EQUINIX INTER DATA CENTER OPTICAL NETWORKS
• METRO CONNECT – Carrier grade metro optical transport
networks interconnecting Data Centers – Metro Connect services (1GE/10GE/
100GE) and transport backhaul for Equinix Interconnect services (CX and IX)
– Built-in optical switch or electrical switch based automatic protection
• HIGH NETWORK PERFORMANCE – Low latency – 50 ms Automatic protection for services – Five nines availability
Metro Connect Network Infrastructure

INTER DATA CENTER OPTICAL INTERCONNECTS
• INTRA CAMPUS NETWORKS – SMF only – Same optics interfaces as for intra data center
• INTER DATA CENTER METRO NETWORKS – Compact low power Data Center Interconnect (DCI) platforms – 300 Km reach high capacity (10 -20 Tb/s) optical systems – 100G/200G waves going to 400G/500G/1Tb/s Super-Channels – Cost effective, high density platforms – Simple photonics and ease of management – Open APIs for SDN control and integration – Low cost client optics for hand-off from optical platforms – Dark fiber direct connects with 40 Km/80 Km optics
Requirements
12
DATA CENTER INTERCONNECTIONS ON SUBMARINE CABLES
• NEW SUBMARINE CABLE OWNERSHIP – Content / cloud providers and private ownership of dark
fibers and/or spectrum – Private network traffic (DC to DC)
• Content localisation / Edge caching • Distribution of data centers on different continents
• OPEN SUBMARINE CABLE OWNERSHIP MODEL – Submarine Line Terminating Equipment (SLTE) and wet
plant vendor separation – Advances in line termination technologies – Faster SLTE technology refreshments
• SUBMARINE CABLE TERMINATION AT DATA CENTERS – Faster deployment – Open access and net neutrality
Trans-Atlantic Capacity Used by Source 2010 - 2014
13
DATA CENTERS FOR SUBMARINE CABLE TERMINATION • COLOCATION SPACE AND
POWER – Colocation for SLTE, Power Feed
Equipment (PFE) (option based on distance to beach) and EMS
– Purpose built to meet PFE high power circuit requirements
– Conditioned DC power options for SLTE
• INTERCONNECTIONS TO CUSTOMERS – Fiber Cross-connects – Connections to cloud, content, and
carriers
• OPERATIONS AND MAINTENANCE SUPPORT – On-site electrical & mechanical
engineers – 24x7x365 operations support – Optional services like spares
management – Shared support overhead
structure between many tenants rather than dedicated O&M staff at traditional CLS

• CHALLENGES – Provisioning complexity and delays
coordinating with back-haul providers – Lower resiliency due to less architectural
flexibility and “future proofing” due to back-haul provider dependencies
– Submarine system vendor lock-in with closed system for wet and dry plant equipment leading to slower technological developments for capacity upgrades
– Limited back-haul connection providers to Metro POPs with higher backhaul costs and increased latency
– Cost/complexity of managing cable landing station (CLS) and city POP infrastructure

OPTICAL LAYER SDN USE CASE 2
• End to End Service Provisioning – Provisioned Across Multiple
Vendors At The Same Layer – End To End Resource Visibility – Route Traffic Based On Capacity
And Topology
• Benefits – Tighter Integration With Higher
Layer Services – Operational Simplicity For Multi-
layer Networks – Eliminates Multi-segment Circuit
Provisioning – Avoid Congested Links
