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

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
There are two popular architectures used with FTTH
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
