2138am—Suncity—For the bettor

 The TBC-6240U series 2138am—Suncity—For the bettor products are designed to transmit multiple E1 services over long distances using optical fibers. The 8E1 PDH optical transceivers utilize industry-leading technologies and proprietary VLSI integrated circuits and optical transmission  products developed with dedicated digital multiplexers. This type of device supports point-to-point networking and is easy to install and maintain. With the chassis, the central office and the remote can be unified to achieve fault location quickly. As a result, the fault response speed is saved and the operation and maintenance costs are saved.

The 8E1 PDH  Multiplexer uses large-scale programmable logic devices as the core part, using the latest design technology and large scale programmable integrated circuits for PDH optical transmission system to provide 16M transmission capacity.

 The circuit part of the equipment is all-digital circuit, the whole machine is reliable, stable, low power consumption, high integration, small size, easy to install and maintain.

 Equipment to meet the needs of telecom operators and private network users, in line with telecommunications standards. Suitable for power, postal services, banking and China Unicom, mobile telecommunications and other users needs, in line with the standards used by telecom operators;

  Abundant bit expenses Offer the transmission of main channel business of E1/G.703 interface and a high-speed data passway, offer RS232 low-rate data passway, official contact passway, network management passway at the same time.

 A variety of models to choose from, to meet different needs. Suitable for point-to-point optical transmission link for the public network and private network to provide high-quality, flexible and reliable digital optical transmission circuit.

 The optical transceiver has the advantages of high integration, strong reliability, low power consumption, small size and complete functions. It can also work stably under harsh environment. Machine installation without any adjustable point, easy to use, easy to maintain;

 The internal hardware and software are modular structure. Hardware part uses a large-scale FPGA, set encoding, decoding, information insertion, alarm switching in one, the circuit becomes simple, thereby enhancing the reliability of the machine, especially for high reliability requirements of the occasion.

Such as: mobile, China Unicom, telecommunications, electricity, public security, military, highway, aviation and other specialized communications networks; high degree of integration of hardware circuits, the whole power consumption is less than 10W; provide 8 E1 ports, E1 port uses digital clock recovery circuit and Digital smooth phase-locked circuit; Has a complete centralized monitoring function and sound and light alarm function; Circuit design ingenious and concise, equipment work is stable, the failure rate is extremely low. Supply voltage can be -48VDC / 24VDC / 220VAC arbitrarily choose one; optional multi-mode, single-mode dual-fiber, single-mode single fiber.
