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.

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.

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.

SEL-2800 Details

Low-Cost Fiber-Optic Communication
Send serial data 500 meters using multimode optical fiber with standard V-pin connectors. Use data rates from 0-40,000 bits per second. Easy Application
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. Requires no jumpers or settings. Secure and Reliable Data Transfer
Far less susceptible to EMI/RFI than copper links. Improved Safety
Provides improved isolation from ground potential rise and other electrical hazards compared to copper connections.

2800M1

Price: $150.49

Use an SEL Transceiver Mounting Kit and adapter cable when connecting the transceiver to IEDs with an RJ-45 male serial connector or when the mounting depth is an issue (e.g., in switchgear applications). The following kits provide a simple and secure way to remote-mount the transceiver away from the host connector:
