3. OT860 4F 1310nm Optical Transmitter User s Manual 20dB 1 Introduction The OT86 4F Optical Transmitter is a new product developed by Shanghai Qianjin Electronic Equipment Co Ltd The Appearance of the chassis features LCD display thin film switch finger mark free steel plate and a vivid color which make the unit look elegant and modern OT86 4F is one intelligent standard 19 1RU chassis and can be monitored by the network management software in this way the network management software can get clear status of the set OT86 4F optical transmitter uses an internal isolated FP laser diode Its high cost effective and excellent performance are highlighted by its advanced pre distortion correction circuit RF pre amplifier circuit high reliability of the power supply intelligent and efficient element management and unique air flow design 2 Features 45 870MHz bandwidth Low noise low distortion and pre AMP to meet low RF input signal Incorporating circuit design built with RF AMP and pre distortion correction enhanced equipment distortion specification Selective AGC Automatic Gain Control of amplitude variable and field MGC Manual Gain Control enables superior link optimization and variable modulation depth RF drive level Effective RF overdrive protection for LD laser diode alarm and automatic LD shutdown Effective APC Automatic Power Control enable precise optical power levels LCD
4. ion 1s guaranteed This equipment can automatically adjust the RF amplitude with in SdB if the RF signal is too big then 35dBm you can adjust the attenuator on the rear panel to reduce the RF signal from zero to 20 dB to improve CNR Local RF level can be tested from the 20dB port on front panel to get the actual operating RF value 6 Caution 6 1 When you get the Transmitter check it once you find any problem please contact the product supplier as soon as possible 6 2 The transmitter should be properly grounded 6 3 For it running correctly you must wait for half an hour after turn on 6 4 The fiber FC APC connector should be cleaned with absolute alcohol to minimize the additional loss or reflection caused by dust which will affect the specification Connect the tail fiber to FC APC socket on the rear panel and keep the fiber hanging down 6 5 If the laser run well the green LED is on and will flash once a second If it becoming red means the laser is out of working The ALARM red LED will flash if there 1s any fault in this machine When the problem is being solved the transmitter will be operating constantly 7 Complete List a OT86 4F Transmitter one b Power cord one c User s Manual one
