RME Optical MADI SFP Module, Single-Mode, Up to 64 Channels Over Fiber

RME Single-Mode MADI SFP Module: Long-Haul Optical MADI

The RME MADI SFP Module (Single-Mode) is an optical SFP transceiver that adds single-mode fiber MADI to compatible RME devices such as the 12Mic, AVB Tool, and M-1610 Pro. It carries up to 64 audio channels of MADI over single-mode fiber, the fiber type used for the longest optical runs. The module is hot-pluggable and ships with an LC-to-SC adapter cable and coupler for connecting to SC-based MADI gear. For campus-scale and long-distance optical MADI links, this is the specialized module to reach for.

How the SFP Module Adds Optical MADI

SFP (Small Form-factor Pluggable) is a standard modular transceiver slot, and this hot-swappable module converts the host device's electrical MADI signal into light for transmission over fiber and back to electrical at the far end. It carries MADI's full 64-channel payload on a single optical link, turning an SFP-equipped RME port into a fiber MADI connection. Because the transceiver is modular, one device can serve coaxial or optical MADI simply by choosing the right insert. That flexibility underpins RME's SFP-based MADI ecosystem.

Single-Mode Fiber for Long-Distance Runs

This is the Single-Mode (marked SM) variant, built for single-mode fiber, which uses a very narrow core that carries light in a single path with minimal dispersion — the reason single-mode supports the longest optical distances. Single-mode is less common in typical MADI systems and is chosen specifically for long-haul or campus-scale links where multimode's range is insufficient. Like all fiber, it is immune to electrical interference and provides galvanic isolation between endpoints. Choose this module only when your run genuinely needs single-mode reach.

Hot-Pluggable and Single-Mode Compatibility

The module is hot-pluggable, so it can be inserted or removed while the RME MADI device remains powered, keeping the system live during installation or service. It uses an LC fiber connector and includes an LC-to-SC adapter cable plus an SC-SC coupler for SC-terminated fiber. Critically, single-mode gear must be paired only with other single-mode MADI devices at the far end — mixing single-mode and multimode fiber will not work reliably. Matching fiber types on both ends is essential for a stable link.

For Long-Haul and Campus-Scale Optical MADI

Use the single-mode MADI SFP to extend MADI over single-mode fiber for long-haul runs, to add optical MADI to a 12Mic, AVB Tool, or M-1610 Pro, and for install and campus-scale optical MADI links. It suits facilities spread across buildings or sites where distance exceeds what multimode fiber can serve. Confirm that the opposite end uses matching single-mode optics before deploying. Where MADI must travel the longest distances, this module makes the link possible.
