An optical network is a type of data communication network built with optical fiber technology. It utilizes optical fiber cables as the primary communication medium for converting data and passing data as light pulses between sender and receiver nodes.
Optical network is one of the fastest communication networks. It works by using an optical transmitter device to convert an electrical signal received from a network node into light pulses, which are then placed on a fiber optic cable for transport to a receiving device.
Unlike copper based networks, the light pulses of an optical network may be transported quite a distance until the pulses are regenerated through an optical repeater device. After a signal is delivered to a destination network, it is converted into an electrical signal through an optical receiver device and sent to a recipient node.
Moreover, an optical network is less prone to external inference and attenuation and can achieve substantially higher bandwidth speeds than copper networks.
Ubiquitous, high speed and low latency networks will require deep fiberization and high densification. The number of network end points will surge due to increasing FTTx penetration, 5G (10-20x small cells per macro cells) and IoT (up to 10 devices per person). All this will require significant network creation with deep fiberisation and high densification.
With demand for fiber expected to grow at a rapid pace as faster 4G/5G networks are rolled out and new age technologies such as IoT, augmented reality, virtual reality, cloud computing etc. become common place, the OFC industry is on a roll.

Fiber optic network design refers to the specialized processes leading to a successful installation and operation of a fiber optic network. It includes first determining the type of communication system(s) which will be carried over the network, the geographic layout (premises, campus, outside plant (OSP, etc.), the transmission equipment required and the fiber network over which it will operate. Designing a fiber optic network usually also requires interfacing to other networks which may be connected over copper cabling and wireless.
Next to consider are requirements for permits, easements, permissions and inspections. Once we get to that stage, we can consider actual component selection, placement, installation practices, testing, troubleshooting and network equipment installation and startup. Finally, we have to consider documentation, maintenance and planning for restoration in event of a future outage.
The design of the network must precede not only the installation itself, but it must be completed to estimate the cost of the project and, for the contractor, bid on the job. Design not only affects the technical aspects of the installation, but the business aspects also.
Even before the network has been built, decisions are made that will determine important aspects of its future operations and maintenance. Therefore, the best basis for the efficient operation and maintenance is a well-considered and consistent network strategy from the outset. The strategy should cover all aspects of how the network will be built and extended, including the network topology and architecture, the design rules and the choice of equipment. During the strategic planning phase, the network operator decides how the network will be built. There is much more to consider than just the initial investment.
Although it is important to reduce the capex because of its impact on the viability of the business case, the opex should also be carefully considered. For every deployment option the operator should evaluate how this would affect the cost of future operation and maintenance processes, such as customer provisioning, network maintenance and repair, and how easily the network could be extended and upgraded. Please note that this paper focuses on the technical aspects of the deployment strategy only. The dependencies of the ownership and financial models, which also influence strategic decisions, are beyond the scope of the paper and will not be taken into account.
Outside plant installations depend heavily on maps and data about the cable plant route. This can include basic data on the local geology, locations of road, buildings, underground and aerial utilities, and much more. For example the type of ground along the route can determine the methods of underground installation, with deep soil permitting direct burial, other soils requiring trenching and conduit and rocky areas precluding underground installation of any type. Aerial installations must be based on knowledge of the owners of the poles and the processes necessary to gain permission to use the poles and make ready for new cable installations
Lepton’s Network Access (NA) & Smart Inventory (SI) are GIS analysis & Inventory Management platforms created with very detailed & high precision Google maps. Moreover it can be customised as per user requirements of planning and or analysis. It is web based & can be accessible over internet. It does not depend on the system hardware neither has any requirement of additional software installation.
Network Access tool has Geographical data, building data, roads, crossings, railways, landmarks, Soil type data, locality & population data available with PIN codes, Tehasils, villages, cities, districts & State boundaries. That is used for the Desktop Planning of Fiber Network that will reduce the Time, Cost, Manpower requirement for field Surveys. Centralised planning team can monitor field surveys with the help of Lepton’s WorkForce management (WFM) mobile based application tool Smart Patroller. This will help finalising Fiber Network plan with pinpoint accuracy.
While planning we have to consider the existing Fiber network of same operator or other operators, other underground cables, pipelines, power lines etc. With the help of Network Access it is very convenient to plan considering every other considerable aspect.
A bigger challenge for telecos is managing its on field inventory. Even though if it is available to some it’s not accessible or available to all. It’s also has the problem when multiple stake holders carry & manage multiple entities of a single network. Lepton’s Smart Inventory tool specially designed to overcome similar & many other problems.
It has every network component & its inventory available over the GIS platform. As built fiber layouts, chambers, manholes, Joint-closures, documents like requests, permissions, legal authority letters, ROW letters, Site-data like Tower locations, shelters, racks, equipment, cards, antennas & connectivity details. Microwave details, backhaul details, POP locations & every minute details available on Geo-based platform. It can be made accessible to every stake holder in the organization who will be responsible for maintaining and managing this. That helps to do the analysis, understand, manage, maintain and update any changes in the network in easier way.
With the help of Network Access & Smart Inventory together with Smart Fiber it is very convenient to analyse, manage and update every detail of the network.
Analysis tools for every network is available over Network Access platform. Analysis like Feasibility, Grid, buffer, distance, covered population, network KPI, Fiber-cut etc. can be performed easily and faster.
After analysis every change in inventory can be maintained. That will keep track of every update of network, its faults, its implemented solutions and problems faced.
This blog is limited with length. So we could not cover each and every functions and applications of Network Access, Smart inventory.
