Reliable PON Optical Transmission

The PON optical transceiver integrates the optical transmitter and receiver into a compact module, providing the optical interface required by PON network equipment.

For GPON applications, the optical interface follows the physical-layer requirements defined by ITU-T G.984.2, which covers GPON optical transmission parameters, including optical wavelengths, transmitter characteristics, receiver sensitivity, and optical budgets.

A typical GPON configuration provides approximately 2.488 Gbit/s downstream and 1.244 Gbit/s upstream transmission.

Single-Fiber Bi-Directional Transmission

PON networks commonly use a single optical fiber for both upstream and downstream transmission. Different wavelengths are used to separate the two transmission directions through WDM technology.

For example, a typical GPON ONU configuration uses approximately:

• 1490 nm downstream
• 1310 nm upstream

The exact wavelength and optical parameters depend on the selected PON standard and module type.

This single-fiber architecture helps reduce fiber consumption and simplifies the deployment of access networks.

OLT and ONU/ONT Modules

HIPHOTONICS can provide PON optical modules for different positions within the access network.

OLT PON Optical Module

OLT modules are installed in the Optical Line Terminal and provide optical connectivity toward multiple ONUs/ONTs through the passive optical distribution network.

Available configurations can be selected according to:

• GPON
• EPON
• XG-PON
• XGS-PON
• Combo PON
• Other customized PON applications

ONU/ONT Optical Module

ONU/ONT modules are used at the customer-side network equipment and provide optical connectivity between the subscriber equipment and the PON network.

The module can be integrated into compatible ONU/ONT devices to provide reliable fiber access for broadband, voice, IPTV, enterprise, and other services.

Flexible Optical Budget Options

Different PON deployments require different optical budgets depending on the ODN architecture, splitter ratio, fiber distance, connectors, splices, and other passive components.

HIPHOTONICS can provide modules with different optical budget classes, including configurations corresponding to B+, C+, and other project-specific requirements.

ITU-T G.984.2 defines enhanced GPON optical budgets including B+, C+, and D configurations.

This allows network operators to select an appropriate module according to the actual fiber access architecture.

Compatibility and Customization

For telecom operators and system integrators, optical module compatibility is critical.

HIPHOTONICS can provide modules with customized EEPROM coding and compatibility configurations according to the customer's equipment requirements.

Compatibility options can be provided for selected equipment from major network equipment manufacturers, subject to technical verification and sample testing.

Customers can specify:

• Equipment manufacturer
• Equipment model
• PON standard
• Optical budget
• Transmission distance
• Wavelength
• Connector type
• Form factor
• DDM/DOM requirement
• Operating temperature
• EEPROM coding
