1000M SC BiDi Fiber Media Converter, Single Mode RJ45 to Single Fiber Converter, 20km

Product Overview

The Luleey 1000M SC BiDi Fiber Media Converter is a compact Gigabit Ethernet media converter designed for RJ45 to single fiber optical conversion. It provides one 10/100/1000Mbps RJ45 Ethernet port and one SC BiDi single fiber optical port, allowing users to extend Gigabit Ethernet over single mode fiber.

Unlike SFP slot media converters, this product uses a fixed SC BiDi optical interface. It does not require an additional SFP module. The device is normally used as an A/B pair, with one unit transmitting at one wavelength and the other unit transmitting at the paired wavelength over the same fiber core.

This Gigabit BiDi Media Converter is suitable for network projects where only one fiber core is available or where installers want to save fiber resources. It is commonly used for IP camera networks, building-to-building Ethernet links, office cabling, telecom rooms, factory networks, warehouse networks, security systems, and long-distance Gigabit Ethernet extension.

The Luleey Single Fiber Media Converter provides a simple plug-and-play solution for extending Ethernet beyond the 100-meter copper cable limit while reducing fiber core usage.

Specifications

Why Use a 1000M SC BiDi Fiber Media Converter?

Copper Ethernet cable is normally limited to about 100 meters. When the network distance is longer, fiber optic transmission is a better solution.

A 1000M SC BiDi Fiber Media Converter converts RJ45 Ethernet into fiber transmission over a single mode fiber link. It helps extend Ethernet networks across long distances while reducing electromagnetic interference and improving link stability.

The BiDi design is especially useful when only one fiber core is available. Instead of using two separate fibers for transmit and receive, the converter uses two wavelengths over one fiber core.

What Does BiDi Mean?

BiDi means bidirectional transmission. A BiDi media converter uses different wavelengths to transmit and receive data over the same fiber core.

For this product, the A/B pair normally uses 1310nm and 1550nm wavelength pairing. One side transmits at one wavelength and receives at the other wavelength, while the opposite side works in reverse.

This allows the link to work over only one single mode fiber core.

A/B Pair Deployment Notes

This product should normally be used as an A/B pair. Two identical A-side devices or two identical B-side devices will not create a normal BiDi link.

A correct BiDi link needs:

• One A-side converter
• One B-side converter
• One single mode fiber core
• Matching SC fiber connector
• Correct wavelength pairing
• Compatible RJ45 Ethernet devices on both sides

Before installation, engineers should confirm which unit is A-side and which unit is B-side.

Fixed SC BiDi Converter vs SFP Media Converter

This product is different from a 1000M SFP Media Converter.

Choose this 1000M SC BiDi Fiber Media Converter when you need a simple plug-and-play single fiber link.

Choose an SFP media converter when you need to change SFP modules, use different fiber distances, or support different optical connector types.

Important Compatibility Notes

This product uses a fixed SC BiDi optical interface. It is not an SFP slot media converter and does not support inserting SFP modules.

Before deployment, confirm:

• The product is used as an A/B pair
• The fiber type is single mode
• The connector type is SC
• The link distance is within 20km
• The two sides use matched 1310nm/1550nm wavelength pairing
• The RJ45 device supports 10/100/1000Mbps Ethernet
• The power adapter matches the installation requirement

This product is not designed for GPON Stick or GPON OLT Stick insertion because it does not have an SFP slot.

FAQ

What is a 1000M SC BiDi Fiber Media Converter?

A 1000M SC BiDi Fiber Media Converter converts RJ45 Ethernet into single mode fiber transmission using one SC single fiber optical link.

What is this media converter used for?

It is used for Gigabit Ethernet extension, IP camera networks, building-to-building links, office networks, security systems, telecom rooms, and long-distance RJ45 to fiber conversion.

Does this converter use one fiber or two fibers?

It uses one single mode fiber core. The BiDi design allows transmit and receive signals to work over the same fiber using different wavelengths.

Does this product come as a pair?

Yes. This type of BiDi media converter is normally used as an A/B pair for point-to-point single fiber deployment.

What is the transmission distance?

The transmission distance is up to 20km under suitable single mode fiber link conditions.

What connector does the fiber port use?

The fiber port uses an SC UPC single fiber optical interface.

What Ethernet speed does the RJ45 port support?

The RJ45 port supports 10/100/1000Mbps Ethernet.

Can I use this with multimode fiber?

No. This model is designed for single mode fiber.

Can I insert an SFP module into this product?

No. This is a fixed SC BiDi media converter, not an SFP slot media converter.

Can this product be used with GPON Stick or GPON OLT Stick?

No. This model does not have an SFP slot, so it cannot be used by inserting a GPON Stick or GPON OLT Stick. For GPON Stick scenarios, choose a compatible SFP slot media converter.

What is the difference between this product and a 1000M SFP Media Converter?

This product has a built-in SC BiDi optical port and is used for simple single fiber links. A 1000M SFP Media Converter has an SFP slot and supports different SFP modules.
