OPTONE Product Overview

The OPTONE PON OLT SFP Transceiver series offers high-performance, cost-effective modules designed specifically for Passive Optical Networks (PON). Engineered with a standard single-fiber, single-mode SC receptacle, these modules are the backbone of modern broadband infrastructure, providing reliable downstream and upstream connectivity for FTTH (Fiber to the Home) and comprehensive access networks.

Available in both GPON (Gigabit PON) and EPON (Ethernet PON) configurations, our OLT modules support various optical budgets, including Class B+ and Class C+ standards. With fully integrated digital diagnostic capabilities, low power dissipation, and a compact pluggable design, they deliver exceptional reliability for telecom operators, ISPs, and enterprise network deployments.

OPTONE Key Features & Benefits

Single-Mode SC Receptacle: Equipped with a precision single-fiber SC interface, simplifying optical fiber termination and reducing deployment complexity.

Advanced DDM/DOM Support: Features a built-in digital diagnostic interface fully compliant with SFF-8472, allowing network administrators to monitor real-time module parameters such as temperature, voltage, and laser power.

Low Power Dissipation: Highly optimized internal circuit design minimizes heat generation and energy consumption in high-density OLT chassis equipment.

Standard Power Supply: Operates reliably and consistently on a standard +3.3V single power supply.

Commercial Temperature Range: Engineered to maintain stable transmission capabilities within a standard operating temperature range of 0°C to +70°C.

RoHS-6 Compliant: Manufactured with eco-friendly materials, strictly complying with international RoHS-6 environmental and safety standards.

OPTONE Key Applications

OPTONE PON OLT transceivers are highly versatile and widely deployed in global telecommunications and broadband infrastructure:

GPON OLT Systems: Providing high-speed, asymmetric bandwidth (Tx 2.5G / Rx 1.25G) for next-generation gigabit optical line terminals.

EPON OLT Systems: Delivering cost-effective, symmetric bandwidth (Tx 1.25G / Rx 1.25G) for ethernet-based passive optical networks.

Access Networks: Serving as the central hub connection for wide-scale residential and commercial broadband rollouts.

FTTH (Fiber to the Home): Enabling the critical central office (CO) optical link required to deliver triple-play services (voice, video, data) to end-users.

OPTONE Frequently Asked Questions (FAQ)

Q1: What is the difference between GPON and EPON OLT modules?

GPON (Gigabit PON) modules provide asymmetric data rates (2.5Gbps downstream and 1.25Gbps upstream), making them ideal for modern, high-bandwidth FTTH networks. EPON (Ethernet PON) modules offer symmetric data rates (1.25Gbps for both upstream and downstream) and are widely used in enterprise and legacy ethernet-based access networks.

Q2: Should I choose Class B+ or Class C+ for my GPON OLT?

The choice depends on your optical power budget and network splitting ratio:
Class B+ provides a standard transmit power (1.5~5dBm) and receiver sensitivity (<-28dBm), suitable for typical GPON deployments with standard split ratios (e.g., 1:32 or 1:64 over shorter distances).
Class C+ offers a higher optical output power (3~7dBm) and better receiver sensitivity (<-30dBm), making it the preferred choice for long-reach applications or scenarios requiring higher split ratios (e.g., 1:128).
