The biggest difference between HMRU and HARU is whether R-OPTIC module exist or not in the enclosure. HMRU receives TX optical signals from ODU and converts them into RF signals. The converted RF signals are amplified through High Power Amp in a corresponding HRDU band combined with UDCU, PAU and Cavity duplexer, and then radiated to the antenna port. When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding HRDU and sends the results to R-OPTIC to make electronic-optical conversion of them. After converted, the signals are sent to a upper device of ODU. HMRU can be equipped with up to four HRDUs (High Remote Drive Unit) and the module supports single band only. HARU receives TX RF signal from HMRU and amplifies through High Power Amp in a corresponding HRDU combined with UDCU, PAU and Cavity duplexer, and then radiated to the CU(Combining Unit) When receiving RX signals through the antenna port, HRDU filters out-of band signal in a corresponding HRDU and sends the results to MHRU through RF cable.

The biggest difference between HMRU and HARU is whether R-OPTIC module exist or not in the enclosure. HMRU receives TX optical signals from ODU and converts them into RF signals. The converted RF signals are amplified through High Power Amp in a corresponding HRDU band combined with UDCU, PAU and Cavity duplexer, and then radiated to the antenna port. When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding HRDU and sends the results to R-OPTIC to make electronic-optical conversion of them. After converted, the signals are sent to a upper device of ODU. HMRU can be equipped with up to four HRDUs (High Remote Drive Unit) and the module supports single band only. HARU receives TX RF signal from HMRU and amplifies through High Power Amp in a corresponding HRDU combined with UDCU, PAU and Cavity duplexer, and then radiated to the CU(Combining Unit) When receiving RX signals through the antenna port, HHRDU filters out-of band signal in a corresponding HRDU and sends the results to MHRU through RF cable.

"The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device."

RSS-GEN, Sec. 7.1.2 (transmitters) Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformment la rglementation dIndustrie Canada, le prsent metteur radio peut fonctionneravec une antenne dun type et dun gain maximal (ou infrieur) approuv pour lmetteur par Industrie Canada. Dans le but de rduire les risques de brouillage radiolectrique lintention desautres utilisateurs, il faut choisir le type dantenne et son gain de sorte que la puissance isotroperayonne quivalente (p.i.r.e.) ne dpassepas lintensit ncessaire ltablissement dune communication satisfaisante.
