Danish researchers have already broken the world record of data transmission and achieved a transmission rate of 43 tbps in optical fiber, thus surpassing their longtime rival Germany. The Danish Technical University uses a single laser transmitter to achieve this speed over a fiber optic line. This transfer speed allows consumers to transfer 1tb of full content and 1gb of DVD in 0.2ms for one-fifth of a second.
This is a milestone in the transmission speed. The holder of the previous record completed a transmission speed of 32 tbps, which is the new speed announced by the German chancellor at the press conference. Moreover, the use of laser transmission in optical fiber means that it can enter the real market faster.
Fibers used in optical fibers are provided by the Japanese company NNT and have seven glass threads or cores, which makes it easier to transmit higher-level data.

Pre-stressed concrete pole mould is used for electronic concrete pole making. Its mainly manufacture technology is longitudinal tension by steel wires. Then it can squeeze out the excess water in the concrete under the centrifugal force. Thus, it can greatly improve the concrete density and strength.
In order to form concrete more quickly to meet the design strength of more than 70%, steam curing can be carried out so as to shorten the mould-releasing cycle.
Our factory produces two categories of Pre-stressed concrete pole steel moulds, DMZ&DMD. The Pre-stressed Electric Poles by this series equipment comply with the China Standard JC/T364-2001.
Features:
1. Welding technology, which enhances the smooth finish of the mould wall, and eliminates the uneven traces of rivet holes. So the concrete poles appearance will be improved significantly.
2. The cylinder is changed to U-type longitudinal stiffeners which can greatly increase the stiffness and flexural strength of the Steel Mould,
3. Install the slot with rubber sealing strip, in order to prevent leakage to ensure quality.
