The Global Optical Network (ON) Market is Continuously Recovering
Explosion Proof Temperature Sensor
The model of explosion-proof temperature sensor is wzpk-22i-b, which is made of stainless steel and has explosion-proof performance. If you want to conduct reliable temperature measurement, you first need to select the correct temperature instrument, that is, the temperature sensor. Thermocouple, thermistor, platinum resistance (RTD) and temperature IC are the most commonly used temperature sensors in testing.
The changes of physical parameters with temperature include expansion, resistance, capacitance, electromotive force, magnetic properties, frequency, optical characteristics, thermal noise and so on. With the development of production, new temperature sensors will continue to emerge.

In the latest market analysis report*, independent telecommunications analysts said Alcatel-Lucent Alcatel-Lucent was the best performer in the first quarter of 2011, with revenues of US$645 million. Compared with the same quarter last year, it increased by 17% and its market share reached 18.4%. This is Alcatel-Lucent's quarterly first-quarter revenue for the first time in the past two years.
Importantly, OVUM Irving found that the annual spending of the fiber network market appears to have turned from red to black in the first quarter of 2011, despite a 1% marginal increase in revenue to $14.6 billion. Annual market share data is often the best indicator of long-term market trends.
Dana Cooperson, OVUM's leader in network infrastructure practices and market researcher, commented: “The fiber network market continues to improve every year. Although the seasonal expenditures in the previous quarter decreased, compared to the growth in the same quarter last year, it is still very People are encouraged."
In fact, it is important that, under the strong growth of the dense wavelength division multiplexing market, and in response to the continued strong growth of IP data traffic, the shift to more fully optimized optical fiber products has resulted in A slight increase in annual expenses.
The Americas also promoted market growth, and annual expenditures in North America, South America, and Central America continued to improve year-on-year.
On the contrary, compared with the same period of last year, the Asia-Pacific region and Europe, the Middle East and Africa continued to stagnate their spending. Market trends in Asia Pacific in the first quarter of 2011 were particularly bleak.
Among the top ten suppliers, between the second quarter of 2010 and the first quarter of 2011, Ciena’s annual market share grew most, while Huawei lost the most market share.
Suppliers with other market share gains are ranked in descending order of occupancy: Ericsson, Fujitsu, Alcatel-Lucent, Cisco, Cisco, and NEC. In other top ten players, the share of Tellabs and NSN Nokia Siemens fell, while ZTE was the same.
