SEL-2829 Single-Mode Fiber-Optic Transceiver/Modem
Improve safety, signal integrity, and reliability by using two optical fibers instead of wire to transfer bidirectional serial data using single-mode optical fiber. Apply for instrumentation, protection, automation and other applications that benefit from economical fiber-optic links up to 23 kilometers long.
Flexible, Long-Range Fiber-Optic Communication
Send serial data up to 23 kilometers using single-mode optical fibers with standard ST connectors. Use data rates from 0-40,000 bits per second. Use selector switch to choose between DCE and DTE standard pin configurations and eliminate the use of adapters.
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 continuous light pulses for simpler testing with an optical meter. Apply with ST® 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. Edge emitting laser provides component isolation and low power consumption.
Improved Safety
Provides improved isolation from ground potential rise and other electrical hazards compared to copper connections.
Connect the SEL-2829 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.
Distribution system restoration using Mirrored Bits communications between distribution feeder protection relays.
Substation data acquisition and control between a station communications processor and a SCADA master.
Fiber-Optic Cables and Jumpers
For limited space, use C780 cable
