10X10 100G optical transceiver module multi-source protocol
According to the news on March 7, in December last year, Google (Google) and industry manufacturers jointly launched the 10X10G 100Gbps optical transceiver module multi-source agreement (MSA). These manufacturers claim that their joint 10X10 MSA protocol has been successfully used in existing 100Gbps optical communication equipment. When developing multi-source, low-cost optical communication products (such as 100G Ethernet and OTU4) in the future in the optical communication field, the 100G MSA specification will be referred to.
The 10X10 multi-source protocol requires that 10 electrical signal channels with a rate of 10 Gbps be directly grafted onto 10 lasers with a rate of 10 Gbps. The transmission of the first laser module needs to pass through a single-mode fiber, and the distance must reach 2 kilometers. MSA members said that they will gradually extend the transmission distance of 2 kilometers to 10 kilometers, and at the same time, they will develop higher-density communication modules.
It is reported that the 10X10 MSA is a product of the bandwidth requirements of some high-speed optical network potential users in the industry. As an advocate, Google will develop 100G Ethernet products and transmit them through single-mode fiber. The transmission distance is 2 kilometers, which is cheaper than IEEE 100GBase-LR4 PMD. However, IEEE 100GBase-LR4 PMD requires that four electrical signals with a rate of 25 Gbps be directly grafted onto four lasers with a rate of 25 Gbps. The initial cooperative members include: Google, Brocade, JDSU, and Santur. MSA now has 18 members, including: Huawei, Facebook, BTI Systems, AMS-IX, MRV, EXFO, Enablence, CyopTIcs, AFOP, Oplink, Hitachi Cable America, Kotura, Effdon, and CorTIna Systems.
Variable Frequency AC Power Supplies
The VFP series AC Power Supplies are high precision, high efficiency, low THD adjustable AC power supplies that converts the input mains power through AC→DC→AC conversion, and gives a pure sine wave AC output with adjustable voltage & frequency within a certain range. Also known as Variable Frequency AC Power Source.
According to the difference in the number of output phases, it can be divided into single-phase and three-phase AC power supplies.
The output power of single-phase adjustable AC power supply ranges from 500VA to 200KVA, the output power of three-phase adjustable AC power supply ranges from 3KVA to 600KVA, the output voltage is divided into 0 ~ 150Vac, 150 ~ 300Vac, and the output frequency is adjustable from 45Hz to 70Hz with 50/60Hz fixed frequency output.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies.
This series of adjustable AC Power Supplies have comprehensive protection functions, such as: over voltage, over current, over temperature and short circuit protections, which can protect the AC power supplies and DUT from damages. At present, it is mainly used for Various electrical appliance manufacturers conduct grid simulation tests on electrical appliances according to the voltage/frequency requirements of different countries. Imported electrical appliances are used for the domestic demand for variable voltage and frequency conversion, as well as various AC motors and AC transformers.
