EPON OLT SFP PX20+++ 7dB Price in Kenya

The EPON OLT SFP PX20+++ 7dB is a high-power PON optical transceiver designed specifically for the PON port of an EPON Optical Line Terminal (OLT).

It provides the optical interface between the OLT and the passive optical distribution network connecting multiple EPON ONUs or ONTs.

A typical PX20+++ module supports 1.25Gbps EPON transmission, up to 20km over single-mode fibre, 1490nm downstream transmission and 1310nm burst-mode upstream reception. It uses a single-fibre BiDi optical interface, commonly with an SC connector. 

This module should not be confused with an ordinary 1G Ethernet SFP. Although both use an SFP form factor, the PX20+++ is designed specifically for EPON OLT PON applications.

EPON OLT SFP PX20+++ 7dB Specifications

Manufacturer specifications consistently identify the PX20+++ class as 1.25G, Tx1490nm/Rx1310nm, 20km and ≥7dB, although exact optical characteristics vary between brands. 

What Is an EPON OLT SFP Module?

An EPON OLT SFP is the optical transceiver installed in an EPON OLT's PON interface.

It converts the OLT's electrical data into optical signals for transmission through the passive optical network and receives upstream optical signals transmitted by subscriber ONUs.

A basic network looks like:

Internet → Router → EPON OLT → PX20+++ SFP → ODF → Feeder Fibre → PLC Splitter → Distribution Fibre → ONU → Customer Router

The module therefore forms a critical optical interface between the active OLT and the passive fibre network.

What Does EPON Mean?

EPON stands for:

Ethernet Passive Optical Network

It uses Ethernet technology to deliver broadband services over a passive optical distribution network.

What Does PX20+++ Mean?

PX20 identifies an EPON optical power/reach class, while manufacturers commonly use additional + designations to differentiate higher-output module variants.

A current manufacturer family provides:

Another EPON transceiver manufacturer similarly specifies PX20+ at 3–5dB, PX20++ at 5–7dB and PX20+++ at ≥7dB. 

Because naming conventions can vary between suppliers, always verify the actual datasheet rather than relying only on the number of plus signs.

7dB EPON OLT SFP

The 7dB PX20+++ is designed to provide stronger optical output than lower-class PX20+ and PX20++ modules.

This can be useful in networks containing:

• Longer fibre routes

• Larger splitter ratios

• Multiple connectors

• Several fusion splices

• Distribution boxes

• Patch panels

• Additional optical losses

However, a higher-power module does not eliminate the need to calculate the complete optical budget.

1.25Gbps EPON Transmission

The PX20+++ supports a typical serial optical interface of:

1.25Gbps

and complies with IEEE 802.3ah EPON specifications. 

This is suitable for standard GEPON/EPON access networks.

20KM Transmission Distance

A typical PX20+++ module supports fibre transmission distances of up to:

20 kilometres

over suitable single-mode fibre. 

The actual achievable distance depends on the complete optical distribution network rather than fibre length alone.

Factors include:

Fibre Loss + Splitter Loss + Connector Loss + Splice Loss + Engineering Margin

1490nm Downstream Wavelength

The OLT module transmits downstream data at approximately:

1490nm

The signal travels:

OLT → ONU

This carries downstream traffic toward subscribers.

1310nm Upstream Wavelength

Subscriber ONUs typically transmit upstream toward the OLT at:

1310nm

The PX20+++ therefore contains a burst-mode receiver designed to detect 1310nm upstream signals from multiple ONUs.

Manufacturer specifications identify the module as using a 1490nm DFB transmitter and 1310nm APD burst receiver. 

Single-Fibre BiDi Operation

EPON uses bidirectional transmission over one fibre strand.

The same fibre carries:

1490nm ↓ Downstream

and

1310nm ↑ Upstream

This means a PON connection does not require separate Tx and Rx fibres like a conventional duplex Ethernet SFP.

A current PX20+++ specification explicitly lists BiDi operation over one single-mode fibre core. 

SC Fibre Connector

PX20+++ modules commonly use an:

SC optical connector

Some versions specifically use SC/UPC.

Before purchasing, confirm the connector required by the installed OLT and patch cord.

EPON OLT SFP vs Normal Ethernet SFP

You should therefore not install an ordinary 1G Ethernet SFP in place of an EPON PON module simply because both physically fit an SFP cage.

The PX20+++ optical module provides the PON-side optical interface required by a compatible EPON OLT. Its 1490nm transmitter sends downstream data through the passive optical network, while its 1310nm burst-mode receiver handles upstream signals transmitted by multiple ONUs.

The single-fibre architecture makes EPON particularly efficient for FTTH deployments because one feeder fibre can be divided through passive PLC splitters to serve multiple subscribers. The OLT controls communication between the shared optical interface and registered ONUs.

Selecting a 7dB-class PX20+++ module can provide additional optical headroom compared with lower-output variants, but the network must still be designed according to splitter insertion loss, fibre attenuation, connector losses, splice losses and reserve margin.

EPON OLT SFP for ISPs

The module is particularly suitable for:

• Local ISPs

• Estate internet providers

• Apartment networks

• Rural broadband networks

• Campus networks

• Business parks

• WISPs expanding into fibre

• Metropolitan fibre operators

EPON OLT SFP for HIOSO OLTs

HIOSO PX20-series modules are available for compatible HIOSO EPON platforms.

A current Kenyan listing specifically identifies the HIOSO EPON OLT SFP PX20+++ 7dBm as intended for long-reach FTTH and ISP access networks.

Compatibility should still be confirmed against the exact OLT model and firmware.

EPON OLT SFP for HA7304

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

A current Fiber Optics Kenya listing for the HA7304 identifies:

• 4 PON ports

• Up to 256 ONUs

• Up to 1:64 split per PON

• 1490nm Tx / 1310nm Rx

• Up to 20km transmission

• WEB/SNMP/CLI management 

A compatible PX20-series module provides the optical interface for each PON port.

EPON OLT SFP for 1x8 Splitters

A 1x8 splitter divides one PON optical path into eight outputs.

Conceptually:

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

Actual subscriber count and reach depend on the complete network design.

EPON OLT SFP for 1x16 Splitters

A 1x16 splitter creates 16 optical outputs.

Compared with 1x8, it introduces additional splitter loss, making optical-budget calculation increasingly important.

EPON OLT SFP for 1x32 Splitters

1x32 is a common FTTH split configuration.

A properly engineered PX20+++ network can be used with 1x32 splitting, subject to:

• Fibre distance

• Splitter insertion loss

• Connector loss

• Splice loss

• ONU sensitivity

• OLT receiver characteristics

Can PX20+++ Support 1x64 Splitting?

Some EPON OLT platforms support up to 1:64 logical/physical splitting per PON port.

For example, the HIOSO HA7304 is specified for a maximum 1:64 split ratio and up to 64 ONUs per PON port.

However:

1:64 support does not mean every 20km route will support 64 subscribers.

Optical loss increases as splitter ratio increases.

Optical Splitter Loss

Typical PLC splitter insertion loss increases with split ratio.

Therefore:

1x4 < 1x8 < 1x16 < 1x32 < 1x64

in terms of optical loss.

A network designer must ensure that the optical power reaching the ONU remains within the ONU's receiver range and that upstream power reaching the OLT remains within the OLT receiver specification.

Optical Power Budget

A simplified calculation is:

Available Optical Budget – Network Losses = Remaining Engineering Margin

Network losses include:

• Fibre attenuation

• PLC splitter loss

• Connectors

• Adapters

• Fusion splices

• Mechanical splices

• Patch cords

• Dirty connectors

Do not select a PX20+++ module based only on distance.

PX20+ vs PX20++ vs PX20+++

These particular power classifications are manufacturer-specific examples. 

PX20+++ 7dB vs 8dB

Higher-output versions are also available.

Current Kenyan listings include:

Higher output can provide more flexibility in demanding ODN designs, but excessive optical power and receiver limits must also be considered.

DDM / Digital Diagnostic Monitoring

Many PX20+++ modules support an SFF-8472-compatible digital diagnostic interface. 

Depending on the OLT, DDM can provide information about:

• Module temperature

• Supply voltage

• Transmit status

• Receive status

• Optical parameters

This can simplify troubleshooting and maintenance.

Hot-Swappable SFP Design

The PX20+++ uses a small-form-factor pluggable design.

This makes it easier to:

• Install

• Replace

• Upgrade

• Troubleshoot

• Change optical power classes

Always follow the OLT manufacturer's maintenance procedure when replacing an active PON module.
