1411T TOSLINK Optical Transmitter Module, 16 Mbps Board-Mount SPDIF TX
The 1411T is a board-mount TOSLINK (SPDIF) optical transmitter module that converts an electrical NRZ signal into light sent over plastic optical fiber. With a 2.7–5.5 V supply, a DC–16 Mbps signaling range and a through-hole DIP socket package, it is built for digital-audio output boards, SPDIF interfaces and short-range industrial optical links on POF.
Product Overview
The 1411T integrates an LED emitter, drive circuitry and a standard TOSLINK female socket in one through-hole package. The socket accepts a conventional TOSLOCK-style POF plug, and the two plastic locating feet keep the module seated on the PCB while the pins carry power, signal input and ground. Supplier listings also reference this family as DLT1411 / T01-class TOSLINK transmitters.
Per the module’s electro-optical datasheet, the emitter runs from a 2.7–5.5 V supply and handles NRZ signaling from DC to 16 Mbps. On POF (APF-style fiber) the specified reach is 0.2–20 m, which covers typical SPDIF digital-audio runs and equipment-to-equipment optically isolated links.
Wavelength labeling note: the supplier listing, folder name and photo watermark mark this part “460 nm”, while the supplied electro-optical table lists peak emission wavelength λp = 640–670 nm and the operating photos show a red emitter glow. Please confirm the target wavelength against your receiver before volume orders — see the verification notes below.
Key Features
- Integrated TOSLINK female socket — mates with standard TOSLOCK POF plugs without separate fiber alignment.
- Wide supply range 2.7–5.5 V, compatible with 3.3 V and 5 V logic boards.
- NRZ signaling DC–16 Mbps; suits SPDIF stereo audio and low-speed industrial optical links.
- Specified up to 20 m transmission distance on POF; typical fiber-coupled output −17 dBm.
- Through-hole DIP package with locating feet for hand or automated soldering.

Applications
- SPDIF/TOSLINK digital-audio output on DACs, sound cards, TVs and set-top boxes.
- Optically isolated audio and control links between chassis in professional and industrial equipment.
- Short-range POF data links where galvanic isolation and noise immunity matter.

Ordering & Customization
The 1411T ships as a through-hole transmitter module. We can also supply it mated with cut TOSLOCK POF cable assemblies made to your length. To prepare a quote, please confirm: quantity, the target wavelength (see the note above), your supply voltage and logic level, and the required fiber length with connector side. Email our sales team your board outline or drawing.
FAQ
Is the 1411T a transmitter only? Yes. It is the TX side of a TOSLINK link; pair it with a matching TOSLINK receiver module at the far end.
What fiber does it use? Standard TOSLOCK plastic optical fiber (1 mm-core POF with a TOSLOCK plug), matching the datasheet’s “using APF” transmission-distance condition.
Does it work with 3.3 V logic? The supply range is 2.7–5.5 V and input high level VIH ≥ 2 V, so both 3.3 V and 5 V logic interfaces sit within the datasheet limits.
What does −17 dBm mean? Fiber-coupled light output Pf is −21 (min) / −17 (typ) / −15 (max) dBm — the optical power the module launches into the fiber.
