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.
- Flexible, Long-Range Fiber-Optic Communication
Send serial data from 2 to 15 kilometers (9 miles) using multi-mode 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.
- Relay-to-Relay Teleprotection
Connect the SEL-2815 to the EIA-232 port of SEL relays on opposite ends of a protected line, and connect them with two fibers. Use Mirrored Bits® communications for teleprotection schemes including POTT, DCUB, or DCB.
- Communications With SEL-2505 Remote I/O Module
Connect the SEL-2815 to the EIA-232 port of an SEL relay or SEL-2100 Logic Processor. Connect via fiber to an SEL-2505 Remote I/O Module with the ST connectors option. The SEL-2505 provides eight contact outputs and eight logic inputs, and uses Mirrored Bits communications.
