Six industrial serial-over-fiber models for the control world's oldest interfaces — the ones running PLCs, meters, barriers and telemetry that copper limits to a bus-length.
RS232 and RS485 were supposed to be replaced decades ago. Instead they became the permanent plumbing of the physical world: PLCs speak them, meters report on them, barriers, weighbridges, HVAC controllers and legacy telemetry all terminate in a serial port. Their copper limits are severe — RS232 is a room-scale interface, RS485 a site-scale one with strict bus discipline — and both suffer in electrically violent environments. This family of six industrial models converts serial links to fiber, where distance stops mattering and ground loops and surge paths disappear.
The family's documented reference model shows the expected consolidation: a CAN Bus Serial RS232/RS485 to Fiber Optic Converter — the three field buses of a control cabinet over one fiber path. Around it, the family covers the RS485-over-fiber and RS232-to-fiber duties that make up most serial extension work: point-to-point links first, with bus topology questions (multi-drop RS485 networks) handled as the design question they are, in the specifying section.

The complete Industrial Serial Fiber Converter family (6 models) as listed in the manufacturer's catalogue.
Serial specification is exact: which interface (RS232, RS485 2-wire or 4-wire, CAN), which baud rate and parity, and whether the link is point-to-point or a multi-drop bus. Fiber conversion is natively point-to-point; an RS485 bus design must state its drop count so the architecture (bus over fiber vs star from a hub point) is designed, not discovered.
Many serial-over-fiber jobs are not about distance at all: they are about breaking a ground loop or a surge path between buildings or across a plant. If isolation is the driver, say so — it confirms fiber over the cheaper copper repeaters immediately.
Serial's eternal trap is pinout variance. State the connector type and device at each end in the inquiry; the confirmation covers the interface variant so the field install is a plug, not a soldering session.
The bus must be re-architected: fiber segments are point-to-point, so a multi-drop design becomes a chain or star of point-to-point hops. Describe the bus (drops, distances, baud) and the layout will be designed and quoted as a system.
Rate support is per model. Serial jobs live at everything from 1200 baud telemetry to fast control links — state your rate and format (bits/parity/stop) and it is confirmed against the model in writing.
No — the converter is transparent to the bytes. Modbus, proprietary polls and CAN frames pass as they are; the medium changes, the conversation does not.
Send the model name, the distance, the fiber type and the quantity. We will confirm the matching transmitter/receiver pairing, the optical module and the full specification of the exact model in writing before you pay.
