It is rated for a 40 km optical path, uses a single LC bidirectional (BiDi) interface, and transmits at 1550 nm while receiving at 1310 nm. Digital Diagnostic Monitoring (DDM) can provide optical readings through compatible network hardware.

EtherWAN specifies 9\/125 µm single-mode fiber, single LC connectivity, a 1550 nm transmit wavelength, a 1310 nm receive wavelength, DDM support, a 20 dB optical link budget, -3 to +2 dBm output power, and -23 dBm receiver sensitivity. The operating temperature range is 0°C to +70°C.
