8 channels telephone optical multiplexer

8 Channels Telephone Optical Transmitter and Receiver

Item No.:OM-5108

Description:

Telephone Optical Transmitter and Receiver  is a fiber transmission device that transmit telephone signal over fiber. We self-developed this device according with the rapidly increasement of voice private network users . One device can provide maximum 30 channels telephone interfaces (MAX 480 channels by cascading) and 1 channel RS232 ASI (Asynchronous Serial Interface), effectively solve telephone transmission problems of edge customers.
Our telephone optical tansmitter and receiver using private digital multiplexing chip that we owns the entire intellectual property development, it integrates almost all digital logical function so that greatly improve product's function as well as reduce the cost. This eqipment is small in size and easy to installation and maintenance, featured with good performace\working steady and reliable and low consumption. It compliance with telecommunication operating standard, has widely use in various telecommunication operators\government\enterprise and public institution,etc.

Features:

1. Provide 1~30 channels telephone interface, signal(voice) transmit by Fiber or E1 interface
2. With self-developed application-specific integrated circuit as the core, low comsumption and high reliability
3. Compliance with telecommunication operating standard, MTBF more than 100,000 hours
4. Voice interface support CND (calling number display) and anti-pole signal
5. DC48V or AC220V power supply, with ringing current module
6. Max transmission distance is 120km, single fiber both-way module available, save precious fiber resources
7. Super optical dynamic range, useing without any adjustment
8. Strict on raw material chosen and QC to ensure high quality and reliability products
