Are there single-port multimode optical modules

Small Form-factor Pluggable (SFP) optical modules are widely used in networking to facilitate high-speed data transmission over optical fiber cables. They come in two primary types: single-mode (SM) and multi-mode (MM). For example, one module might transmit at 1310nm and receive at 1550nm, while the other does the opposite. This type. Single Mode SFP (SMF) transceivers utilize a narrow 9µm core for long-range, high-bandwidth laser transmission, while Multimode SFP (MMF) leverages a wider 50µm core for short-range cost efficiency.
