SEL-2815
Fiber-Optic Transceiver/Modem
Improve safety, signal integrity, and reliability by using two optical fibers instead of wire to transfer bidirectional serial data. Apply for instrumentation, protection, automation and other applications that benefit from economical fiber-optic links from 2 to 15 kilometers long.
Starting At
$330Fiber-Optic Link—Connect a pair of transceivers and an SEL-C808 Multimode 62.5/125 µm Core Fiber-Optic Cable with ST connectors for EIA-232 communication between devices over a fiber-optic link. Create a link of 2 to 15 km with SEL-2815 Fiber-Optic Transceivers.
Fast Data Rates—Transfer data at rates up to 40 kbps with the SEL-2815.
Safe and Secure Communications—Isolate communications connections from ground potential rise and electrical interference.
Details
Flexible, Long-Range Fiber-Optic Communication
Send serial data from 2 to 15 kilometers (9 miles) using multimode optical fiber with standard ST 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. Order transceivers/modems with male or female DB-9 connectors. Use switch to select DCE or DTE standard pin configurations, and eliminate the need for adapters. Transmits continuous light pulses for simpler testing with an optical meter. Apply with ST pre-terminated fiber cables.
Secure and Reliable Data Transfer
Maximum bit error rate (BER) of 10-9. Far less susceptible to EMI/RFI than copper links. Vertical Cavity Surface Emitting Laser (VCSEL) technology provides component isolation and low power consumption.
Improved Safety
Eye-safe Class 1 laser product. Provides improved isolation from ground potential rise and other electrical hazards compared to copper connections.
Mounting Kits
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:
