Overview
Networks often require conversion from multimode to single-mode fiber, which supports longer distances than MM fiber. Mode conversion is typically required when:
- Multimode equipment is in a building and connectivity is required to an outside plant single-mode network
- Legacy equipment uses multimode fixed fiber LC and SC ports, and connectivity is required to single-mode equipment
- High cost of proprietary Single-mode SFPs
- Connecting multimode network equipment to a single-mode CWDM multiplexer

Multimode to Single-Mode Fiber Conversion Products
iConverter® Transponders and Fiber-to-Fiber Media Converters
iConverter protocol-transparent Fiber-to-Fiber media converters and Transponders support data rates up to 11.32Gbps, and improve the capabilities of existing fiber infrastructure by providing multiple functions in a single network device:
- Multimode to single-mode conversion
- Dual fiber to single-fiber conversion
- Optical amplification and distance extension
- Standard wavelength to WDM wavelength conversion
FlexPoint™ Fiber-to-Fiber Media Converters
FlexPoint unmanaged Fiber-to-Fiber Media Converters provide multimode to single-mode conversion, and support a variety of network protocols, data rates and cabling media types. All Omnitron Systems fiber media converters are backed with a lifetime warranty and free 24/7 technical support.
Multimode to Single-Mode
Convert Multimode to Single-mode Fiber
In this application example, a network requires multimode to single-mode fiber conversion to connect two in-building multimode networks over a single-mode fiber link, which supports longer distances than multimode fiber.
Fiber-to-fiber media converters are used to extend a multimode network across single-mode fiber with distances up to 140km for Fast Ethernet (100Mbps) and 80km Gigabit Ethernet (1000Mbps). In this application, two Ethernet switches equipped with multimode fiber ports are connected utilizing a pair of fiber-to-fiber converters which convert the multimode fiber to single-mode and enable network connectivity across the distance between the switches.
Omnitron Fiber-to-fiber Media Converters and Transponders feature a variety of fixed fiber connectors or SFP transceivers, and can support a variety of network protocols and data rates.
SFP Multimode to Single-Mode
Convert Multimode SFPs to Single-Mode and Save Money with Transponders
In this application example, multimode to single-mode fiber conversion is required for longer network distances. The fiber switches can be Ethernet, Fibre Channel, or any other network protocol. The fiber switches require the use of proprietary (name-brand switch manufacturer) single-mode SFPs that can be very expensive. Using third-party single-mode SFPs can void the manufacturer’s warranty and service contract.
Transponders are used to convert the 850nm multimode to 1310nm single-mode fiber. The transponders with multimode and single-mode SFPs can cost 50% less than buying proprietary single-mode SFPs and installing them in the switches. Since the transponders are external to the switches, they do not void the warranty or service contract from the switch manufacturer.
The iConverter standalone xFF Transceivers have multimode SFPs in one port and single-mode SFPs in the other for multimode to single-mode conversion. For distribution of multiple single-mode fiber runs from a multi-mode switch, xFF Transponder chassis plug-in modules can be installed in a high-density iConverter 19-Module Chassis.
NOTES:
- iConverter xFF Transponders are used for network protocols up to 8.5Gbps, and iConverter XG Transponders are used for network protocols up to 11.32Gbps.
- Transponders can also convert multimode fiber to single-mode fiber with CWDM wavelengths for connectivity to a CWDM multiplexer.
