DCS & WCDMA Dual Band Fiber Optic Repeater
Model: D(L)&W Dual Band FO Repeater MU\-D(LB3) SZALO-W-AF-WB-MU
Model: D(L)&W Dual Band FO Repeater RU\-D(LB3) SZALO-W-AF-WB-RU-43-
The D+W Dual band fiber optical Repeater was developed by SZALO, and features long transmission distance, large power, Omni-directional coverage and multi-area coverage. It can be widely applied outdoor remote coverage instead of the BTS when BTS is few resources, or is used for indoor building and high way, high railway coverage. Because adopting digital filter technique, it features allowing a large number of remote devices, multi frame work, effective signal coverage, and strong anti-interference capability.
Feature
● Support multiple bands at the same time. e.g., DCS1800+WCDMA2100
● Full operation bandwidth system supports multi-operator or multi-network application
● One MU supports up to four RUs
● 20 watts power per band at the antenna connector as required
● 10dB Optical Budget – up to 20km optical distance
● IP65 weatherproof RU with built-in surge protector
● Built-in wireless modem for remote controlling and monitoring
● Comply with ETSI 300 609-4 (GSM) and 3GPP TS25 143 (WCDMA)
