Mitsubishi Electric Corporation will begin sampling "25Gbps DFB lasers" on September 1. The new product is an optical transmission device applied to optical communication between a mobile communication system antenna base station and a switching center responsible for collecting communication signals transmitted by the base station for centralized control. High-speed operation (25Gbps) in a wide operating temperature range (-20°C to +85°C) and a 25Gbps compact transceiver specification (SFP28*4) by the industry's top (July 20, 2016, according to our survey) The external dimensions contribute to the speed of the next generation mobile communication system.
Note: Gbps (Giga-bitsperseconds): communication rate unit capable of transmitting gigabit digital codes per second
2DFB (DistributedFeed-Back) laser: distributed feedback laser. A diffraction grating inside the laser to extract the optical signal at a specific wavelength
New product features
1. Achieve 25Gbps high speed operation and a wide operating temperature range of -20°C to +85°C
· Through the optimization of laser diode structure, it achieves the industry's top transmission speed of 25Gbps in the wide temperature range of -20 ° C ~ +85 ° C (existing product: transmission speed 10Gbps)
· Same as existing products, the communication equipment equipped with this product does not need to be equipped with a refrigerator, and can be set outdoors
2. Maintains the same form factor as existing products and meets 25Gbps compact transceiver specifications
· Developed a high-performance package that minimizes electrical signal loss
· As a non-built-in TO-CAN for the driver IC, it achieves the same external dimensions (φ5.6mm) as the existing 10Gbps DFB laser.
· Helps meet the 25Gbps high-speed operation of small transceiver specifications (SFP28) by using a simple structure of TO-CAN
Summary of samples
Start providing sample targets
The popularity of mobile terminals such as smartphones and tablets has dramatically increased data communication capacity. In order to process a large amount of communication data at high speed, a new generation mobile communication system requires a small transceiver used in a communication device to operate at a high speed (25 Gbps). However, in order to achieve this goal, since the communication device used by the antenna base station is placed outdoors, the DFB laser mounted on the transceiver needs to operate at a high speed over a wide temperature range while ensuring the size conforming to the 25 Gbps compact transceiver specification. All become issues that need to be solved.
In order to meet the above requirements, our company has begun to provide the industry's top-level high-speed operation (25Gbps) in a wide operating temperature guarantee range (-20 ° C ~ +85 ° C), and suitable for 25Gbps small transceiver specifications (SFP28) form factor Sample of the "25Gbps DFB Laser". This contributes to the speed of the next generation mobile communication system.

Variable voltage DC Power Supply support master-slave configuration to increase the output capacity to 576kW. SYS series cabinets use world famous circuit breaker to control the input of each power module inside. After power on, the specified 3U or 6U height power supply will be configured as a Master to control all of the slave units. CSP is the Master in SYSA series cabinets, which is equipped with a PDU (Power Distribution Unit) and a CSP (Control & Supervisory Panel).
Connecting the cabinet
1. The cabinets can be connected in parallel in order to increase output power.
â— Maximum 16 units 3U height same model DC power supplies or 6U height same model DC power supplies can be connected via the bus.
â— 16 units each with a power of 18kW are connected together to a 288kW system.
â— 16 units each with a power of 36kW are connected together to a 576kW system.
2. Different height cabinets can be connected in parallel.
