Middle-Mile Networks:What and Why
The level of interconnection necessary for the Internet to function would be impossible if billions of users had to be individually connected to each other as well as to millions of sources of content.
Achieving this interconnection implies a different approach,that of a middle-mile network consisting of long-haul core backbone routes and regional routes,and last-mile providers-not unlike the transportation model of high-capacity long-haul interstate highways that connect to major boulevards and traffic arteries,which then feed traffic into local business parks and residential streets.
In this model,an open-access middle-mile network plays the role of major highways and regional boulevards-bridging the gap between the global Internet and any last-mile providers that wish to connect to it,who then bridge the remaining gap to their individual local residential and business customers,as well as fire,earthquake,climate,and smart city sensors.
A Middle-Mile Network:More Than Just Fiber
01
OPERATIONS &MAINTENANCE
activities are also needed to ensure the network remains up 24/7/365 -especially during emergencies
when first responders will rely on it.
02
COMPLEX HARDWARE
software (and substantial electric power) is required to translate data into light pulses,and to send,amplify, and receive those pulses.
03
WIRELESS EQUIPMENT
can be used to penetrate further into remote areas with special geographic challenges where installing fiber underground isn't cost-effective.
04
"HUTS"OR"VAULTS"
are access points placed along the cable route where last-mile providers can install their own equipment to
connect to the middle-mile network.
Characteristics of A Successful Middle-Mile Network
Since the purpose of an open-access middle-mile network is to bridge the gap between the global Internet at large and last-mile providers,it must consider the needs of these providers to ensure their success.This implies the following middle-mile network characteristics,which increase the attractiveness and usefulness of the network to reach even more communities,create cost savings,add resiliency,and shorten the time to service as well as ensure connections to the global Internet at the most affordable cost:
• Leverage existing infrastructure where possible and appropriate,such as IRUs on already installed fiber,existing rights-of-way,and partner resources through joint builds
• Offer a full suite of on-demand dark fiber and lit/managed services arrived at by trustworthy market research
• Design with resilient ring topologies and redundancy to ensure that spurs are only employed where absolutely necessary and never where fires,earthquakes,floods,or severe weather events can impact service
• Employ a flexible ring cut policy that permits the creation of vaults and meet-me locations where needed by last-mile Internet Service Providers
Glory Optical Communication supplies many kinds of fiber optic splice closures for use in Middle-Mile Networks. We have our own third-party accredited testing center for fiber optic products. Our laboratory can perform more than 10 tests, including IP rating, impact tests, temperature cycling, bending tests, compression tests, etc. We carry out comprehensive quality control of product performance in compliance with RoHS, REACH, IEC, ISO, and other domestic and international standards.
