The LNK-201-1550/LNK-201-1310 is a low noise RF fiber optical transceiver designed for CDMA, GSM, 3G network and broadband RF wireless applications respectively. Single fiber LNK-201 serial covers 350MHz、450MHz、800MHz (CDMA), 900MHz (GSM), 1800MHz (DCS), 1900MHz (PHS), 2.1GHz (WCDMA), 2.2GHz (TD-SCDMA).Each module consists of a master and a slave module，the link from master to slave is called down link， from slave to master as up link. In down link a DFB Laser with 1.5um wavelength is selected as transmitter and an analog PD as optical signal receiver , In up link a 1.3um DFB laser is selected to transmit the optical signal and an analog PD as optical signal receiver. These modules can be used for 20km applications and they are fully compliant with the latest issue of Bellcore GR-253-CORE. • AGC function to realize auto gain compensation for optical transmission.
• Transparent data transmission channel for data exchange.
• Wide-band features for multi-system work.
• Perfect optical and RF features.
• 800M~2.2G
