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.
