Adafruit Iso1540 Bidirectional I2c Isolator

Single-fiber bidirectional router

A BiDi SFP module is a bidirectional fiber optic transceiver that enables simultaneous transmit and receive over a single strand of single-mode fiber, instead of the traditional two-fiber setup. The industry-standard Cisco Small Form-Factor Pluggable (SFP) Gigabit Interface Converter (Figure 1) links your switches and routers to the network. The hot-swappable input/output device plugs into a Gigabit Ethernet port or slot. Optical and copper models can be used on a wide variety of Cisco. While both are compact fiber optic modules for switches and routers, BiDi SFPs uniquely enable bidirectional data transmission over a single fiber strand using Wavelength Division Multiplexing (WDM), contrasting with standard SFP modules requiring two fibers. In practical network deployments, this makes BiDi SFP modules a highly effective solution for.
