Huawei RTN950 ODU Hardware Description

[mohamad]

Hi,

Can anybody share RTN980 ODU 38 GHz hardware description?
I need to know if frequency range of 36-37 GHz is implemented in Huawei ODUs or not.

Regards,

Hi
RTN 950 is a IDU 2U high connectable with at maximumi with 6 IF board (ODU) with 256QAM modulation.
(RTN950A has upto 10 radio directions) with new modem board with 2 xIF with 2048QAM capabilty
this IDU can work with a lot of different ODU
XMCC/XMC2/XMC2H are the last available and XMC3 the current developement

freq plan for ODU 38GHz is 37.044GHz to 40.105GHz goret 1260MHz

i dont think HUAWEI has custom series for 36-37 GHz
that normally it's band dedicated to other applications then PTP
what' s reccommadation ITU you want to be compliant?

seems that Ceragon is offering such kind of ODU @36GHz (RFU odu)
even if very limited in performance : modulations and system gain

3600-36300 36700-3700 RFU-CX-36-TH
36700-3700 3600-36300 RFU-CX-36-TL

700MHz GR

Thanks for your answer.

36-37 GHz channel arrangement is defined in annex 2 of ITU-R F. 749-2 (ITU recommendation for 38 GHz band).
Seems that this range is recommended to use in Russia. GR is 462 according to this annex.

Maybe some eastern European suppliers (Intracom, SAF, ...) do have some sub-bands in the period of 36-37 GHz.

What do you think?
