FX to FX (OPT-1020/2020/4040)

High-performance Fiber-to-Fiber Media Converters (OPT-1020/2020/4040 series). Supports multi-mode to single-mode, BIDI, and SFP-to-SFP optical conversion up to 120km. 3-Year Warranty.

Product Overview

The OPTONE Fiber-to-Fiber Media Converter Series (OPT-1020 / OPT-2020 / OPT-4040) is a specialized optical-to-optical repeater designed to bridge different fiber types, change optical wavelengths, or extend transmission distances. Unlike standard copper-to-fiber converters, these devices accept an optical signal, regenerate it, and transmit it over a different optical medium—enabling seamless multi-mode to single-mode, single-mode to single-mode, or SFP-to-SFP conversions.

Covering Fast Ethernet (155M) and Gigabit (1.25G) applications, these converters can extend network links from 2km up to 120km. Housed in a compact, rugged metal enclosure and backed by a 3-year warranty, they provide a flexible, reliable solution for enterprise campus backbones, telecom service providers, and long-distance infrastructure upgrades.

Key Features & Benefits

Flexible Optical Conversion: Supports 100Base (155M) and 1000Base (1.25G) multi-mode to single-mode, single-mode to single-mode, BiDi, and open SFP-to-SFP conversions.
Long-Distance Extension: Effectively bridges network gaps, extending transmission ranges from 2km (multi-mode fiber) up to 120km (single-mode fiber).
Standalone & Composite Deployments: Can be deployed as a standalone desktop unit or integrated into composite network architectures for flexible node scaling.
Multiple Connector Options: Compatible with standard SC, ST, FC, or flexible SFP optical receptacles depending on the selected model.
Real-Time Status Monitoring: Equipped with front-panel LED indicators (Power Status, FX Link/Act) for instant visual diagnostics and troubleshooting.
Compact & Durable Design: Built inside a rugged metal enclosure with low power dissipation, ensuring high reliability in harsh operating environments.

Frequently Asked Questions (FAQ)

Q1: What is a Fiber-to-Fiber Media Converter used for?
Unlike traditional copper-to-fiber converters, a fiber-to-fiber converter (optical-to-optical repeater) is used when you need to connect two different optical networks or media types together. Common applications include converting multi-mode fiber to single-mode fiber, changing optical wavelengths, converting dual-fiber to single-fiber (BiDi), or bridging different connector types without replacing existing cable plants.
Q2: What is the difference between OPT-2020 and OPT-4040?
The OPT-2020 series features fixed 1×9 optical transceivers welded on the board with specific multi-mode, single-mode, or BIDI specifications. In contrast, the OPT-4040 features two open SFP slots, giving network engineers the ultimate flexibility to change distances, wavelengths, or fiber types simply by plugging in different SFP modules.
Q3: Can I use BiDi (A/B) converters with standard single-mode converters?
No. Bi-Directional (BIDI) models (such as OPT-1020SA/B or OPT-2020A/B) utilize WDM technology to transmit and receive data over a single strand of fiber using complementary wavelengths (e.g., Tx1310/Rx1550 paired with Tx1550/Rx1310). They must always be ordered and deployed in matching A/B pairs.
