Multiband Fiber Optical Booster

Transcript

Multiband Fiber Optical Booster ML-B6040 ML-B6040 is a multi-band fiber optical amplifier adopting state-of-art DPD (Digital Pre-Distortion) technologies. DPD is the one of the most fundamental building blocks in wireless communication systems. With DPD, the power amplifiers can be made to be far more efficient. MBOL is targeted for indoor wireless coverage working with BTS at high efficiency and low power consumption while still maintaining spectral compliance, reducing system capital and operational expenditure. ML-B6040 supports up to 6 bands:  700band  900 band  1800 band  2100 band  2600 band Features  DPD-LPA uses combination of DPD algorithm, digital circuit and radio circuit  25% DPD-LPA efficiency, much higher than feed-forward MCPA (10%)  Mixed mode (GSM\WCDMA\LTE) for each band without interference  Built-in control panel with colorful touch screen for easy maintenance  Remote control and monitoring through wireless modem  Compact design with field replacement for key modules  each MU can carry up to 8 ORUs © 2010-2013 |1 TX1 E/O Tx Signal Splitting TO-ORU-1 700~2700M TX2 TX3 TX4 E/O RX1 Rx Signal Combiner TO-POI RX2 E/O RX3 RX4 E/O TO-POI TX1 E/O Tx Signal Splitting TX2 TO-ORU-8 700~2700M TO-ORU-1 700~500M TX3 TX4 E/O RX1 Rx Signal Combiner RX2 E/O RX3 RX4 E/O MU Note: optional parts for MIMO is marked in yellow TO-ORU-8 700~500M ML-B6040-MUX 700MHz UNIT 800/900/2100/1 800/2600Tx/Rx O/E 900MHz UNIT Tx TO-MU 700~2700M 2100MHz UNIT Rx 1800MHz UNIT POI Tx Tx TO-DAS Tx Tx 2600MHz UNIT Rx Rx TO-DAS Rx ORU Solution © 2010-2013 Rx ( ML-B6040-RUB) |2 Specification Downlink Specification Uplink Frequency (MHz) 700M LTE 728~ 756 900M LTE 930~ 960 1800M LTE 1805~ 1880 2100M UMTS 2110~ 2170 2600M LTE 2620~ 2690 700M LTE 698~ 787 900M LTE 885~ 915 1800M LTE 1710~ 1785 2100M UMTS 1920~198 0 2600M LTE 2500~25 70 Output Power 20W 20W 20W 20W 20W -10dBm -10dBm -10dBm -10dBm -10dBm Gain 50±3dB Pass Ripple Band +/- 3dB ≤-45dBc@±5MHz(3GPP) ≤-50dBc@±10MHz(3GPP) ACLR AGC Yes FL-2.5MHz～F0-6MHz: ≤-50dBc/30kHz or -13dBm/3kHz GSM900/ DCS1800 F0-6MHz～F0-1.8MHz: ≤-50dBc/30kHz or -13dBm/3kHz In-band F0+1.8MHz～F0+6MHz: ≤-50dBc/30kHz or -13dBm/3kHz F0+6～FH+2.5MHz: ≤-50dBc/30kHz or -13dBm/3kHz Out-band -36dBm/30KHz 9kHz < f < 150kHz≤ -36dBm / 1kHz 150kHz < f < 30MHz≤ -36dBm / 10kHz 30MHz < f < 1GHz≤ -36dBm / 100kHz 1GHz < f < Fc1-60MHz or 2100MHz which is higher ≤ -30dBm / 1MHz Spurious Emission UMTS900/2100 Fc1-60MHz or 2100MHz whichever is higher < f < Fc1-50MHz or 2100MHz whichever is higher ≤ -25dBm / 1MHz Fc1-50MHz or 2100MHz whichever is higher < f < Fc2+50MHz or 2180MHz whichever is lower ≤ -15dBm / 1MHz Fc2+50MHz or 2180MHz whichever is lower < Fc2+60MHz or 2180MHz whichever is lower ≤ -25dBm / 1MHz Fc2+60MHz or 2180MHz whichever is lower< f < 12.75GHz ≤ -25dBm / 1MHz 9kHz
