SEL-2812 IRIG-B бүхий шилэн кабелийн дамжуулагч

Improve safety, signal integrity, and reliability by using two optical fibers instead of wire to transfer bidirectional serial data plus an IRIG-B time synchronization signal. Apply for instrumentation, protection, automation, and other applications that benefit from economical fiber-optic links up to 4 km long.


Transfer Data Plus Synchronize Time Economically
Use data rates up to 115.2 kbps for a full duplex serial link with up to 4 km of multimode optical fiber. Use the same transceivers/modems and fibers to simultaneously transfer simplex IRIG-B time code.

Apply Easily
Plug the transceiver/modem directly onto a standard 9-pin serial connector (DB-9). No special mounting is required. The SEL-2812 receives power from the host device via the connector; no separate power supply or power wiring is needed. It uses popular ST connectors and requires no jumpers or settings.

Improve Communications Reliability
Apply in harsh electrical and physical environments. The SEL-2812 is far less susceptible to EMI/RFI than copper links, with a maximum bit error rate of 10-9.

Improve Safety
Provide improved isolation from ground potential rise and other electrical hazards compared to copper connections. The SEL-2812 is an eye-safe, Class 1 laser product.
