Product Overview
The industrial‑grade 1/2‑channel bidirectional RS‑422 optical transceiver converts bidirectional RS‑422 signals into optical signals for transmission over fiber optic cables. It features SC, FC, or ST connectors and supports either single‑fiber or dual‑fiber configurations. This RS‑422 optical transceiver addresses the limitations of conventional RS‑422—such as short transmission distances and poor immunity to interference—while also mitigating electromagnetic interference, ground‑loop noise, lightning strikes, and voltage surges, thereby significantly enhancing the reliability, security, and confidentiality of data communications.
This product features a DIN‑rail‑mountable aluminum‑profile heat‑dissipating enclosure, dual redundant DC power inputs, an IP40 protection rating, and an extended operating temperature range of –40 to +85°C, ensuring long‑term, stable, reliable, and safe performance in harsh environments—including high and low temperatures, dust, and electromagnetic interference. It is suitable for use in telecom equipment rooms, LED display communications, security surveillance, intelligent transportation systems, power monitoring, environmental monitoring, and other demanding applications.
Product Features
1. Supports 1/2/4-channel RS-422 bidirectional data interfaces.
2. Industrial rail-mounted installation, IP40 protection rating.
3. Wide operating temperature range: -40°C to +85°C.
4. Serial port baud rate: 0–115,200 bps.
5. Operating wavelength: 850/1310 nm (multimode), 1310/1550 nm (single-mode).
6. The optical port supports FC, SC, and ST interfaces; multimode transmission ranges from 0 to 2 km, while single-mode transmission spans 0 to 120 km.
7. The status indicator lights are fully equipped, making the operating status immediately clear at a glance.
8. Built-in lightning protection circuitry significantly reduces damage caused by lightning-induced surges.
