Dymec model 5845 and 5846 Serial Fiber Links are link/repeaters for EIA 422 and 485 data connections. The 5845/5846 Links provide reliable serial data connectivity over fiber optic facilities in harsh environments where immunity and signal isolation are critical. Optical connectivity provides flexibility, extended distance, operational safety, reduced equipment outages due to electrical surges, and improved signal quality and network performance.
5845/5846 Links support signal rates from DC to 2 Mbps and operate either full- or half-duplex over single- or multimode fiber. Links are easily fieldconfigurable for point-to-point, master/slave, loop, bus or star topologies. The 5845/5846 also interoperate with 5843/5844 RS232 Links, the Dymec Network Integration System and Optical Star products to costeffectively create highly scaleable data networks with minimum electrical signal exposure.
Dymec Links are substation-hardened to IEEE 1613 specifications. They operate in an extended temperature range and optionally take DC power directly from station battery. Flexible mounting options, diagnostic LEDs and integrated optical and electrical signal test features make turning up Link networks simple.
