Summary
l OS-3200 is field bidirectional optical receiving equipments, developed and researched especially for metropolitan area networks; with building block design for the whole structure, and nice flexibility to meet user’s networks requirements. RF motherboard is detachable and the positive RF transmission is designed based on the bandwidth of 1000MHz
l With excellent detecting circuit, networks system which is compatible with HMS standards, and to monitor the networks through network responder; configure the unit with two-way receiving modules, two-way reverse optical transmitting module, one power supply module and one network responder module
Features:
l With building block design for the whole structure, and nice flexibility to meet user’s networks requirements
l Adopt the world-level high-sensitivity optical detector at the optical receiving part
l Use low-noise DFB laser at the reverse part, imported low-noise push-pull amplifier module at the forward stage, and imported power-doubled amplifier module at the backward stage( GaAs is available according to user’s requirements)
l With two-way optical receiving modules, two-way optical transmitting module, which can be switched automatically and manually according to user’s requirements
l The output level at the four output port can reach 114dBuv, and each forward channel is amplified and equalized independently; the output level and output slope can be adjusted independently; with test port in line
l With test port for both forward and backward direction; plug-in port for reverse modulation signal; both features can make modulation and maintenance more convenient
l Inset excellent condition-detecting circuit and network-monitoring system, which is compatible with HMS standards, to greatly enhance the security and reliability of networks
l With detachable power supply module and high-reliability switch power supply, which has over-voltage and over-current protection
