Introduction
IMC-P21A-G2 PoE+ Fast Ethernet-to-fiber media converters are designed to provide reliable and stable 10/100BaseT(X)-to-100Base-FX media conversion. These converters are classified as power source equipment (PSE) and are used to directly power up powered devices (PDs), eliminating the need for additional wiring. The IMC-P21A-G2 PoE+ Fast Ethernet-to-fiber media converters provide up to 30 watts of power for PoE+ port in standard mode and allow highpower output of up to 36 watts for heavy-duty industrial PoE devices, such as weather-proof IP surveillance cameras with wipers/heaters, highperformance wireless access points, and IP phones. The IMC-P21A-G2 media converters are highly versatile and with SC or ST fiber ports, can transmit data with high EMI immunity for up to 40 km from the device to the control center. The PoE+ Fast Ethernet-to-fiber media converters support a variety of useful functions, as well as PoE diagnostics, Link Fault Pass-through, storeand- forward mode, and pass-through mode. The IMC-P21A-G2 converters support IEEE 802.3/802.3u/802.3x with 10/100M and MDI/MDI-X autosensing, providing a complete solution for your industrial Ethernet networks.

When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power. 2. Compute the “Typical Distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB). 3. An OS1 cable can be used for single-mode models. However, an OS2 cable is required to achieve a transmission distance of 40 km.
