Input Power Limit Function (Tx Input ALC)

A Tx input Auto Level Control function built into the BIU can limit input power levels if the increase past

the limit set by the input AGC function. For example, in the case where the 850 cellular band has two

input ports to support both two different carriers, these input powers may be different from each other.

There is an input attenuator in the first stage of the MDBU. Through the input AGC function, the input ATT

is adjusted according to input power. If input power increases, the input ATT is adjusted to limit the this

increase. If the input power decreases, the input ATT will return to the initial ATT setting.

13.6

Optic Loss Compensation

The DAS can automatically compensate for optical loss up to a maximum 5dBo. To turn on this feature,

set Tx OPTIC COMP of the MRU to ON and ensure the MRU/ARU is properly communicating with the

ODU or OEU. For 1dBo of optical loss, set the Tx OPTIC ATT at 1dB; for 5dBo of optical loss, set Tx

OPTIC ATT at 4dB. OPTIC COMP works only one time before it stays dormant.

LD POWER is the output level of the MRU Laser Diode, which is sent back to the headend by the MRU.

PD POWER is the input level of the Photo Diode signal from the headend. The figure below shows a

screenshot for Optical Information in the MRU setup screen.

Figure 13.1 – Optical Loss Information

During optical compensation, the RESULT field will display PROCESSING and then show the result:

•

Success: Optic compensation is successfully performed

•

Over Optic Loss: Optic loss exceeds 5dBo

•

Communication Fail: Communication between the ODU and MRU failed.
