Overview
The ZJIC200-1F2S is an industrial gigabit fiber-to-serial protocol converter that converts a single 1000Base-X fiber port (SC/ST/FC, single-mode or multimode) into 2 × RS232/485 serial channels for long-distance transmission of serial data over fiber. It ships in AC 220V (100–240V) single-input, DC 24V (12–36V) or DC 48V (36–56V) dual-input power variants, with reverse-polarity and overload protection, drawing a maximum of 3 W. Housed in a fanless IP40 metal enclosure (120×32×95 mm) that supports desktop, DIN-rail or wall mounting, it operates from -10 to +60°C in the standard version or -40 to +75°C in the wide-temperature version — suited for industrial sites that need to carry legacy RS232/485 serial equipment over a gigabit fiber link.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual fiber-to-serial specifications.
Fiber-to-Serial Conversion PointGenuine photoelectric conversion: the 1000Base-X fiber signal is converted directly to 2 × RS232/485 electrical serial channels — a true fiber media/protocol conversion point, not a copper Ethernet pass-through.
Legacy Serial Equipment NetworkingBuilt for exactly 2 × RS232/485 channels (5-pin terminal) — the right port count to bring PLCs, RTUs or meters with only a serial interface onto a gigabit fiber network.
DIN-Rail Cabinet Mount for Wide-Voltage RetrofitDefault DIN-rail installation plus selectable AC 220V (100–240V) or DC 24V/48V (12–36V/36–56V) input lets the unit drop straight into an existing electrical cabinet alongside other DIN-rail gear, no separate power adapter needed.
Outdoor Wide-Temperature CabinetThe wide-temperature variant operates from -40 to +75°C (storage to -40~85°C) with strong EMC immunity (EN61000-4 series, Level 3) — suited to unheated outdoor cabinets in cold or hot climates.
Desktop Plug-and-Play DeploymentUnlike DIN-rail-only fiber converters, the -1F2S also supports desktop mounting — place it on a bench or shelf for quick commissioning or a temporary serial-over-fiber test link, no cabinet or rail required.
Tunnel / Underground M&E MonitoringDual power input (DC 24V/48V models) plus Level-3 EMC immunity and reverse-polarity/overload protection support the reliability tunnels and underground electromechanical rooms demand.
Not a good fit if:
- Not for direct copper-Ethernet extension or camera/PoE aggregation — this model bridges 1000Base-X fiber to RS232/485 serial only; it has no RJ45 Ethernet ports.
- Not a managed switch — no VLAN, ERPS/RSTP ring redundancy or L2 management; it is a fixed point-to-point protocol converter.
- Fiber interface is fixed (1000Base-X, non-SFP) — fiber mode, connector (SC/ST/FC) and single/dual-fiber must be chosen at order time, not swapped in the field.
Key Features

Custom & OEM →Fiber-to-Serial Converter FAQ — ZJIC200-1F2S
What does the ZJIC200-1F2S convert?
It links one 1000Base-X gigabit fiber port to two RS232/485 serial channels on 5-pin terminals, carrying serial data from PLCs, meters or access controllers over fiber for long distances. Forwarding is store-and-forward with a 1K MAC address table and 1 Mbit packet buffer.
How far can the fiber link reach?
Multimode fiber covers 2 km; single-mode options reach 20, 40, 60 or 120 km. The fixed optical port is available with SC, ST or FC connectors, in single-mode or multimode and single- or dual-fiber versions — specify the distance and connector when ordering.
Which power supply options are available?
Three variants: AC 220V (100–240V) single input, or DC 24V (12–36V) and DC 48V (36–56V), both DC versions with dual redundant inputs on a 4-pin terminal. Consumption is just 3 W maximum, with reverse-polarity and overload protection built in.
Can it work in hot or freezing outdoor cabinets?
The standard version operates from -10 to +60 degC and the wide-temperature version from -40 to +75 degC, at 5–95% non-condensing humidity with storage from -40 to +85 degC. The IP40 metal housing carries EN61000-4 Level 3 EMC immunity for electrically noisy industrial sites.
How is it mounted and what warranty applies?
The compact 120 x 32 x 95 mm metal case mounts on a DIN-rail by default, with desktop or wall-mount as options. LEDs show power, fiber-port and serial-port status at a glance. MTBF is rated at 320,000 hours and the converter carries a 5-year warranty.
