48 Channels PCM Voice Telephone fiber opticalmedia converter with 10/100Mbps Ethernet, 

Long working distance up to 20Km.

Default ship with FC optical interface, SCoptional, if need, leave us message after order.

Overview:

The 48 channels telephone over fiber optictransceiver adopts the most advanced all-digital video and optical fibertransmission technology in the world, which avoids the shortcomings of analogfrequency modulation, phase modulation, amplitude modulation optical transceiver,crosstalk interference, two-way telephone crosstalk, and product performancesusceptible to environmental factors. The 1-48 channels telephone issynchronized in real-time on a single-core fiber, without distortion, and withhigh quality. The plug-and-play design makes installation easy and eliminatesthe need for on-site adjustment. The optical modules and core circuits areimported industrial grade chips, full surface mount, and advanced switchingpower supply, anti-electromagnetic radiation devices and other technologies.High, all optical and electrical interfaces are in line with internationalstandards, ensuring that the product can run continuously for long periods oftime without failure in various complex environments. Through the all-digital uncompressedtransmission of telephone signals, all digital series optical transceivers havethe ability to ensure high-quality signal transmission indicators no matter howcomplex optical transmission links. The all-digital optical transceiversupports single-mode or multi-mode optical fiber transmission, and the opticalinterface form FC/ST/SC is optional. The all-digital optical transceiver alsoprovides a wealth of power, fiber link status, telephone, network signal input,output, data input, output effective indication function, making userinstallation and debugging very convenient.
