EPON OLT PX20+++ Price in Kenya

The EPON OLT PX20+++ is a high-power optical transceiver module designed for the PON interface of an EPON Optical Line Terminal (OLT).

It provides the optical connection between an EPON OLT and subscriber ONUs or ONTs through the passive optical distribution network. Typical PX20+++ modules operate at 1.25Gbps, transmit downstream at 1490nm, receive upstream at 1310nm, use single-mode fibre and support transmission distances of up to approximately 20 kilometres. 

Unlike a normal Ethernet SFP, the EPON PX20+++ is designed specifically for point-to-multipoint PON networks, where one OLT port can serve multiple subscriber ONUs through passive PLC splitters.

EPON OLT PX20+++ Specifications

A current JFOPT PX20+++ specification lists 1.25Gbps, 1490nm/1310nm operation, 20km reach, 7–9dBm transmit power, -32dBm receiver sensitivity, SC interface, DDM and less than 1W power consumption for that specific model. 

What Is EPON OLT PX20+++?

The PX20+++ is the optical transceiver installed in a compatible EPON OLT PON port.

Its job is to convert the OLT's electrical network data into optical signals that travel through the fibre network.

A typical EPON network works like this:

Internet → Router → EPON OLT → PX20+++ SFP → ODF → Fibre → PLC Splitter → FAT → Drop Fibre → EPON ONU → Customer

Downstream data travels from the OLT toward subscribers at approximately 1490nm, while subscriber ONUs transmit upstream toward the OLT at approximately 1310nm. 

What Does EPON Mean?

EPON means:

Ethernet Passive Optical Network

It is a fibre access technology based on Ethernet and standardized under IEEE 802.3ah.

EPON is commonly used for:

• Fibre to the Home

• Fibre to the Building

• Fibre to the Office

• Estate internet

• Apartment networks

• Campus networks

• ISP last-mile networks

• Rural broadband deployments

What Does OLT Mean?

OLT means:

Optical Line Terminal

The OLT is installed on the ISP or service-provider side of the network.

It:

• Connects the fibre access network to the ISP backbone

• Controls subscriber ONUs

• Allocates upstream transmission

• Sends downstream traffic

• Handles VLANs and subscriber services

• Manages the EPON network

The PX20+++ module provides the optical interface used by the OLT to communicate with the optical distribution network.

What Does PX20+++ Mean?

PX20 identifies an EPON optical class designed for access networks with distances up to approximately 20km.

Manufacturers commonly use additional + designations to identify progressively higher optical-output variants.

One current manufacturer family lists:

These naming conventions are not completely uniform across manufacturers, so the actual Tx power, receiver sensitivity and optical budget should always be checked on the supplied module's datasheet.

PX20+++ 7dBm

The 7dBm PX20+++ is one of the common high-output EPON OLT modules.

A current Kenyan HIOSO listing identifies a PX20+++ 7dBm single-mode fibre module for FTTH and ISP deployments at approximately KES 3,900. 

A manufacturer example lists:

Tx Power: 7–9dBm
Receiver Sensitivity: approximately -32dBm
Reach: 20km
Connector: SC
Speed: 1.25Gbps. 

PX20+++ 8dBm

Higher-output variants are also available.

A current HIOSO 8dB EPON module listing specifies:

• 8dB class

• Tx1490nm

• Rx1310nm

• Up to 20km

• SC connector

• Single-mode fibre

• Hot-swappable SFP form factor 

The current listed Kenyan price is approximately KES 4,300. 

PX20+++ 9dBm

9dB-class EPON OLT SFP modules are available for more demanding network designs.

A current Kenyan HIOSO listing specifies:

• 9dB class

• 1490nm downstream

• 1310nm upstream

• 20km reach

• SC connector

• Single-mode fibre

• SFP form factor 

Higher output alone does not guarantee better network performance. The complete ODN must still be engineered correctly.

1.25Gbps EPON OLT Module

The typical PX20+++ provides a serial optical rate of approximately:

1.25Gbps

This is standard for many GEPON/EPON OLT applications.

Both Optinet and Miray list 1.25G Tx/Rx operation for their PX20+++ products. 

1490nm Downstream Transmission

The OLT transmits downstream optical data using:

1490nm

The direction is:

OLT → Splitter → ONU

This carries subscriber internet traffic toward customer premises.

1310nm Upstream Reception

The subscriber ONU normally sends upstream information at:

1310nm

The direction is:

ONU → Splitter → OLT

The PX20+++ uses a burst-mode receiver because numerous ONUs share the same PON port and transmit during allocated upstream time slots.

DFB Transmitter

Typical PX20+++ modules use a:

1490nm DFB laser transmitter

DFB means:

Distributed Feedback Laser

This type of laser provides the optical output required for long-distance single-mode fibre transmission.

APD Burst Receiver

The receiver commonly uses:

1310nm APD + TIA

APD means:

Avalanche Photodiode

It provides high receiver sensitivity, which is important because upstream ONU signals must pass through:

• Long fibre routes

• PLC splitters

• Connectors

• Splices

• Distribution boxes

before reaching the OLT.

Current PX20+++ specifications identify 1490nm DFB transmitters combined with 1310nm APD burst receivers. 

Single-Fibre BiDi Operation

EPON transmits upstream and downstream traffic through one fibre core.

It works because different wavelengths are used:

1490nm → Downstream

1310nm → Upstream

The wavelength separation takes place inside the module.

This means:

One Fibre Strand = Bidirectional EPON Communication

SC Connector

Most PX20+++ OLT SFP modules use a:

Single SC connector

Current JFOPT, Miray and Optinet specifications all identify single SC connectivity. 

Before purchasing, verify whether your deployment requires:

• SC/UPC

• Another manufacturer-specific connector configuration

The EPON PX20+++ module is an essential component in an OLT-based FTTH network. It provides the actual optical interface through which one PON port communicates with multiple subscriber ONUs.

Because EPON uses passive splitters rather than powered switches throughout the outside fibre distribution network, the optical performance of the OLT module becomes particularly important. Every splitter, connector, splice and kilometre of fibre adds loss to the optical path.

PX20+++ modules provide higher optical output than lower PX20 classes, giving network designers more headroom when deploying larger splitter ratios, longer routes or networks with multiple passive components. However, the module should still be selected according to an engineered optical budget rather than choosing the highest possible output.

EPON OLT PX20+++ for HIOSO

HIOSO is one common EPON equipment brand available in Kenya.

Current Kenyan listings include both HIOSO PX20+++ 7dB modules and complete HIOSO EPON OLT systems. 

Compatibility should always be confirmed against the exact OLT model.

EPON OLT PX20+++ for HA7304

The HIOSO HA7304 is a compact four-port EPON OLT.

A current Fiber Optics Kenya listing describes the HA7304 as supporting:

• 4 PON interfaces

• Up to 256 ONUs

• Up to 1:64 split per PON

• Up to approximately 20km under suitable network conditions

• Web, SNMP and CLI management 

The OLT requires compatible EPON PON transceivers for optical network connectivity.

PX20+ vs PX20++ vs PX20+++

The exact classifications can differ by manufacturer. 

EPON PX20+++ vs Normal 1G SFP

A conventional Ethernet SFP should therefore not be used as a replacement for a PX20+++ PON module.

EPON PX20+++ vs GPON OLT SFP

Similar wavelengths do not make EPON and GPON modules interchangeable.

EPON OLT PX20+++ and PLC Splitters

PON networks use passive optical splitters to distribute one OLT optical interface to several customers.

Common splitter sizes include:

Each increase in split ratio increases optical loss.

EPON PX20+++ with 1x8 Splitter

A 1x8 PLC splitter divides one optical input into eight outputs.

Typical layout:

OLT PX20+++ → 1x8 PLC → 8 Distribution Fibres

This generally leaves significantly more optical margin than very high split ratios.

EPON PX20+++ with 1x16 Splitter

A 1x16 splitter can serve up to sixteen optical branches.

Actual subscriber numbers can differ because networks may use:

• Cascaded splitters

• Multiple FATs

• Spare ports

• Different ODN architectures

EPON PX20+++ with 1x32 Splitter

1x32 splitting is widely used in FTTH deployment.

However, the network designer must account for:

• Splitter insertion loss

• Fibre attenuation

• Connector loss

• Splice loss

• Patch-cord loss

• Engineering reserve

Can PX20+++ Support 1x64?

Some EPON platforms support up to 1:64 split ratios.

For example, the current HA7304 specification states up to 64 ONUs per PON interface. 

That does not mean every network can operate at 20km with 64 subscribers.

The optical budget must still support the complete ODN.

EPON Optical Budget

The optical budget determines whether sufficient signal reaches both ends of the network.

A simplified calculation is:

Transmitter Output – Total ODN Loss = Received Optical Power

ODN loss includes:

• Fibre attenuation

• PLC splitter loss

• Connectors

• Adapters

• Fusion splices

• Mechanical splices

• Patch cords

The resulting received power must remain within the receiver's specified operating range.

Why Higher PX20+++ Power Helps

A stronger OLT transmitter can provide additional headroom for:

• Larger splitter ratios

• Longer feeder routes

• Multiple connectors

• Cascaded distribution points

• Higher splice counts

• Future network expansion

But increasing transmitter power is not a substitute for fixing excessive fibre loss.

Receiver Sensitivity

Receiver sensitivity describes the weakest optical signal the OLT receiver can reliably detect.

Current manufacturer examples vary:

• Miray lists receiver sensitivity below approximately -30dBm for its PX20+++ module. 

• JFOPT lists approximately -32dBm for its particular PX20+++ model. 

Therefore, use the datasheet of the exact supplied module for optical calculations.

Receiver Overload

The receiver also has a maximum safe input level.

For example, JFOPT lists approximately -8dBm receiver overload for its PX20+++ model.

This is another reason why simply choosing the strongest module is not always the correct network-design decision.

DDM / DDMI Support

Many PX20+++ modules provide Digital Diagnostic Monitoring.

This can help compatible OLT equipment monitor parameters such as:

• Module temperature

• Supply voltage

• Optical transmit conditions

• Optical receive conditions

• Diagnostic status

Miray, JFOPT and Optinet all identify diagnostic monitoring support on their PX20+++ designs. 

Hot-Pluggable Design

PX20+++ modules use the SFP form factor and are designed to be hot-pluggable.

This simplifies:

• Installation

• Maintenance

• Module replacement

• Network upgrades

• Troubleshooting

Always follow the OLT manufacturer's recommended replacement procedure.

Testing an EPON PX20+++ Network

Several tools are useful when commissioning an EPON network.

Optical Power Meter

An optical power meter can verify the signal reaching the ONU or OLT.

PON Power Meter

A PON-specific power meter can measure PON wavelengths more appropriately than a conventional optical meter.

OTDR

An OTDR can identify:

• Fibre length

• Breaks

• Bad splices

• Connector reflections

• Excessive attenuation

• Macrobends

VFL

A Visual Fault Locator helps identify basic fibre continuity and visible faults over shorter distances.
