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.
