Gigabit Passive Optical Network (GPON)

Gigabit Passive Optical Network (GPON)

Gigabit passive optical network (GPON) is the fastest, longest life, lowest cost network infrastructure available on the market. Genuine future offers a Proof network access network with future flexibility and upgrade capability.

This high bandwidth, power-saving, green technology is transforming various businesses and government agencies. Includes mining accommodation camps, hotel and multi-residential accommodation, the layout of campus-style buildings, retirement villages, residential and commercial developments, and corporate and high-rise buildings.

GPON or ‘Gigabit Passive Optical Network’ is a point-to-multipoint mechanism access system.

The main feature of a gigabit passive optical network (GPON) is the use of passive splitters that enable single-feeding fiber from a central location of the network provider to serve multiple users in their homes and small businesses.

Gigabit Passive Optical Network (GPON) uses Advanced Encryption Standard (AES) for security purposes, is designed to be functional in both hardware and software, and supports block lengths of 128 bits and lengths of 128, 192, and 256 bits.

GPON also supports all types of Ethernet protocols.

Working of Gigabit Passive Optical Network (GPON)

Using passive splitters, GPON enables a single fiber to use a single fiber and gives the end-user the ability to combine multiple services on a single fiber data network.

Gigabit passive optical network (GPON) is also fully scalable without network recycling. Systems can be configured for up to thousands of users with multiple OLT chassis.

So as usage trends evolve and bandwidth requirements for end-users increase, GPON enables future upgrade migration without infrastructure changes.

The end result is a future-certified, customized, high-capacity fiber network for CCTV and webcams, security systems, interactive signage “PIDS”, video on demand, high-speed internet, PMS integration, high or all types of IP-based services, ultra high definition IPTV, Control access control and door entry, VoIP telephony, traditional along with analog telephony, automatic minibar system, POS terminals, and Wi-Fi access node.

Components of Gigabit Passive Optical Network (GPON)

IPU-T Recommendation Series G. GPON shows an increase in bandwidth compared to APON and BPON. GPON can be applied to many areas. Desktop (FTTT) fiber applications are distributed in fiber, usually using GPON single-mode, simplex optical fiber connectors, and passive optical splitter to provide precision termination using angle polished connectors (APCs). This GPON system has four main components: optical line terminal (OLT), transmission medium (cabling and components), fiber optical splitter, and optical network terminal (ONT).

Optical Line Terminal (OLT)

OLT is a device that acts as a service provider endpoint of a passive optical network. It is an active Ethernet integration device that is usually located in the data center or main equipment room. An OLT converts an optical signal transmitted from a fiber into an electrical signal and presents it to the core Ethernet switch. Replaces multiple levels 2 switches at the OLT distribution point. OLT distributing signals are connected via optical splitters with backbone cabling or horizontal cabling, connected to the optical network terminal in each work area outlet.

Transmission Medium

Gigabit passive optical network (GPON) transmits signals through passive, physical cabling infrastructure. Transmitted media include copper, fiber optic patch cords, attachments, adapter panels, connectors, splitter, and other materials. All of these broadcast media components must be factual in a channel loss budget to get better performance.

Fiber Optic Splitter

The fiber optic splitter, also known as the beam splitter, is an integrated waveguide optical power distribution device. With this fiber optic splitter, multiple devices can be served from a single fiber. It is one of the most important passive devices in the optical fiber network. This is especially useful in GPON, EPON, and FTTX, etc. PON typically connects a single fiber from OLT to multiple ONUs. Connectivity between OLT and ONU is achieved using fiber optical splitters. The number of outputs in the splitter determines the number of partitions. Split ratios often consist of 1: 4, 1: 8, 1:16, 1:32 and 1:64. The inclusive loss of a typical 1×32 optical splitter ranges from 17 dB to 18 dB. Fiber optic splitter includes fused binocular tapper (FBT) splitter and planar lightwave circuit (PLC) splitter.

Optical Network Terminal (ONT)

The ONT also called a modem, connects to the termination point (TP) with an optical fiber cable and connects to your router via a LAN / Ethernet cable. It converts the optical signal into an electrical signal to be delivered to the last device. OPT always has multiple Ethernet ports for connection of IP services with CPU, phone, wireless other access points, and other video components.

Benefits of Gigabit Passive Optical Network (GPON)

1. Fast and Reliable Technology

GPON’s passive optical network delivers much more bandwidth capability than conventional networks, with speeds up to ten times faster than the (conservative) NBN plan!

The life of the cabling is longer, more accessible, and less susceptible to interference, and there are faster connector solutions.

2. Cost-Saving Technology

Switching to a gigabit Passive Optical Network (GPON) enables many short and long-term cost savings. Using 80% less copper and 60% less energy than traditional networks, GPON is the lowest-priced network infrastructure available in the market.

There are also lower training, maintenance, installation, and operational costs with GPON. At the same time, a gigabit Passive Optical Network (GPON) extends the life cycle of network infrastructure.

GPON fiber is also less lightweight, saving large costs for large projects and cabling transportation.

3. Safe Technology

Gigabit passive optical network (GPON) delivers more network security with fewer service interruptions.

Secure security measures on physical layers, data layers, and end-user ports reduce or minimize the likelihood of denial of service (DOS), redirects, or other malicious attacks.

4. Green Technology

GPON technology allows businesses and government agencies to increase their green star ratings. GPON systems use fiber optic cabling, which is made from glass that can be recycled.

As well as using up to 90% less copper and 60% less electricity than traditional networks, current environmental benefits include a reduction of up to 90% in air conditioning requirements.

5. Space Saving Technology

Gigabit passive optical network (GPON) duplicate infrastructure eliminates the need for a full multiple com room.

And GPON uses only one cable, instead of more than one cable, GPON technology also reduces the special requirements for cable routes by up to 80%.

6. Future-Proofed Technology

Because GPON delivers fiber to the room, there is no need to replace the entire network as the technology evolves.

The system will support progress to the end user’s technology requirements without having to replace or upgrade the GPON infrastructure.

And recent advances in GPON technology (NGPON2 and XGSPON) mean that the bandwidth requirements of end-users may exceed the next two or three generations of GPON technology.

Disadvantages of Gigabit Passive Optical Network (GPON)

Installers need to be careful about mechanical joints to minimize losses and attention. They need special staff and equipment to cut the fiber.

Identification and correction of reflections are in the downstream channel (downstream from the user’s ONT to the OLT) and in the ascending channel (upstream from the ONT to the switchboard with the OLT).
