SRAL XD Supporting Frame for Remote Mounting

A new supporting frame version replaces the present one used for remote mountingremote mounting of ODUs in (1+1) Hot (1+1) Hot Stand ByStand By (Balanced and Unbalanced)

This Supporting Frame is derived from thederived from the new new ssupporting upporting fframe for integrated mountingrame for integrated mounting. It has the same structure with, in addition, the proper material for pole or wall mounting. In this case the waveguide is still necessary.

Available frequency bands: 15,15, 18,18, 23,23, 26,26, 38 GHz38 GHz

As it concerns 7,8,13 GHz the present design As it concerns 7,8,13 GHz the present design of supporting frame remains unchanged.of supporting frame remains unchanged.

SRA L Catalogue updateSupporting Frame for Integrated Mounting

As an alternative to present supporting frame for remote mounting, this new version is suitable for integrated mountingintegrated mounting of ODUs in (1+1) (1+1) Hot Stand ByHot Stand By configuration (Balanced and Unbalanced)

No need for waveguide

The result of this type of mounting is a compact structurecompact structure, that allows to hide the ODUs behind the antenna, with a minimum environmental impactminimum environmental impact.

This solution is available for 15,15, 18,18, 23,23, 26,26, 38 GHz 38 GHz RFRF bands bands.

It is suitable with SRA L antennas antennas withwith diameter 30, 60, 80 cm.diameter 30, 60, 80 cm.

Same management system (NetViewer)

TMN compatibility. Same DCN already installed can be re-used. No need for external devices to connect SRAL XD TMN I/F to SRA L TMN I/F.

Same antennas and supporting frames of SRA L (identichal mechanical interfaces):common inventory

Same IDU/ODU cable and connection kits:common inventory

16 TCM system gain in line with SRA L: easy migration from 8xE1 SRA L to 16xE1 HD (same RF band occupancy) without need to increase antenna diameter

ODU ND is on-air compatible with SRA L 16xE1 (4CPM modulation)asymmetrical links are possible, but only with SRA L IDU Universal
