Optical

The increasing use of internet demands very high bandwidths. High speed data sharing and multitasking across multiple platforms at home requires great capacity and one way to fulfil this capacity is to bring optical fiber to the home.

Fiber-optic communication is based on the principle that light in a glass medium can carry more information over longer distances than electrical signals can carry in a copper or coaxial medium or radio frequencies through a wireless medium.

The purity of today's glass fiber, combined with improved system electronics, enables fiber to transmit digitized light signals hundreds of kilometers without amplification. With few transmission losses, low interference, and high bandwidth potential, optical fiber is an almost ideal transmission medium.

Fiber to the home (FTTH) configuration is the most suitable to meet the speed requirements of today. FTTH provides the highest speeds and a future-proof network infrastructure.

Why Fiber over Copper?

  • Higher bandwidth over long distances
  • Ease of installation, significantly lower maintenance
  • Very low operational costs
  • Immune to Electromagnetic interferences
  • One cable for all communication needs

Types of fibers

  • Multimode Fibers: Core diameter will be between 50-100 microns
  • Singlemode Fibers: Core diameter will be between 8-10 microns
Fiber Type Core Diameter Cladding Diameter ITU-T Standards
OM1 62.5 microns 125 microns As Per TIA/EIA
OM2 50 microns 125 microns G-651.1
OM3 50 microns 125 microns G-651.1
OM4 50 microns 125 microns G-651.1
OS1 or OS2 8 to 9 microns 125 microns G-652 or G-652D
SM Bend Insensitive 8 to 9 microns 125 microns G-657

Plicing is the process of joining two fibers together

  • Fusion Splicing
  • Mechanical Splicing

Other important parts

  • Splice protection sleeve
  • Connector
  • Ferrule

Multifiber Connectore (MTP Systems)

  • MTP is a connector used in datacentre applications where number of interconnections are high and faster performance (10G & 100G)
  • Increases the fiber density – MTP carries 12 to 72 times more fibers than the standard SC connector
  • Ferrule is made of thermoplastic material with relatively high thermal stability and easy machineablity
  • Guide pins and adaptors help alignment of 12-72 fibers in a single mating

Asia continues to make strides in the FTTX market

Asia's FTTH subscriber base is clustered around Japan, South Korea, China, Taiwan and Hong Kong

  • Point to Point (P2P) connectivity architecture, which uses all active components throughout the chain
  • Point to Multi-Point (P2M)/ Passive Optical Network (PON) connectivity architecture which uses passive optical splitters at the aggregation layers

Point to multipoint FTTU network

Gigabit Passive Optical Network (GPON) is the leading FTTH standard. Its main characteristic is the use of passive splitters in the fiber distribution network, enabling one single feeding fiber from the provider's central office to serve customers in multiple locations

GPON technology has the active network elements OLT (Optical Line Termination) at the central office and ONT (Optical Network Termination) at the subscriber site. Typical GPON configuration consists of a single PON port at the OLT and a number of ONTs connected to it over a single fiber feeder.

GPON has a downstream capacity of 2.488 Gb/s and an upstream capacity of 1.244 Gb/s which is shared among users. Encryption is used to keep each user's data secured and private from other users.

Today's Applications: "Triple Play"

True triple-play services require bandwidth from 25 to 100 Mbit/s to the subscribers
