Improve safety, signal integrity, and reliability by using two optical fibers instead of wire to transfer bidirectional serial data plus an IRIG-B time synchronization signal. Apply for instrumentation, protection, automation and other applications that benefit from economical fiber-optic links up to ½ kilometer long
Fiber-Optic Link—Establish EIA-232 communication between devices over a fiber-optic link, 1 to 500 meters long, by connecting a pair of transceivers and an SEL-C805 Multimode 200 µm Core Fiber-Optic Cable with V-pin connectors.
Safety and Security—Install fiber-optic connections to isolate communications from ground potential rise and electrical interference. Both the SEL-2800 and the SEL-2810 alarm with a visible red light (650 nm), allowing simple visual troubleshooting.
Fast Data Rates—Transfer data at rates up to 40 kbps with less than a 15 µs delay using the SEL-2800 Fiber-Optic Transceiver, or use the SEL-2810 Fiber-Optic Transceiver With IRIG-B to transfer data and IRIG-B time codes at rates up to 20 kbps with less than 50 µs delay.
Low-Cost Fiber-Optic Communication
Use data rates from 0–20,000 bits per second for a full duplex serial link with up to 500 meters of multi-mode optical fiber. Use the same transceivers/modems and fibers to simultaneously transfer simplex IRIG-B time code.
Plug transceiver/modem directly onto a standard 9-pin serial connector (DB-9). No special mounting is required. Receives power from the host device via the connector; no separate power supply or power wiring is needed. Transmits visible light (650 nm) for easy inspection. One pair of fibers handles duplex serial data link and simplex IRIG-B time code link. Requires no jumpers or settings
Secure and Reliable Data Transfer
Far less susceptible to EMI/RFI than copper links.
Provides improved isolation from ground potential rise and other electrical hazards compared to copper connections.
