AC/DC Main Power Supply in Optical Communication Equipment Application
The rapid growth of the telecom industry is being fueled by the proliferation of smart devices, the growth of cloud computing, and the increasing demand for secure telecom networks. This is followed by the widespread deployment of 5G networks, continuous improvement and upgrade of telecom infrastructure, and growing concerns about telecom energy consumption, which drive the need for reliable and efficient power solutions.
Different communications equipment may have different requirements for power supply. Let's briefly analyze the power solutions for common applications in the telecom industry to see what kind of power supply they need and what kind of power supply the MORNSUN can provide.
DC/DC Converter in BBU (baseband processing unit) Application
A Baseband Processing Unit (BBU) is a piece of equipment in a telecommunications network that is used to process baseband signals. The BBU is located in the server room and is connected to the remote radio unit (RRU) via a fiber optic link. One BBU can connect multiple RRUs at one time, to realize the function of distributed base stations.
The power solution for this application normally uses a 48VDC input high-power brick package DC/DC power supply, providing power to the following RF transceiver systems, digital systems, etc. Therefore, there are specific requirements for the load efficiency, ripple noise, power density and other performance of the DC/DC power supplies.
MORNSUN's economical open-frame brick package power supply VCB/VCF series adopts variable frequency and active clamp technology, which can effectively improve the conversion efficiency of the power supply at each load level. The average efficiency at 25%, 50%, 75% and 100% load points is >90%. Taking 1/4 brick power supply as an example, the efficiency of 25% load is up to 94% (mainstream efficiency is mostly 90%), and the efficiency of 50% load and 100% full load is even up to 95%.
In addition, this series of power supplies has other advantages such as a wide operating temperature range, excellent EMC performance and a DOSA standard brick package for high compatibility.
PoL Power Supply in Bearer Network Application
The bearer network, located between the access network and the switch, can be used to transmit various voice and data. Its mainstream power supply solution in this application is as follows:
ACDC main power supply + DCDC power supply + PoL power supply, of which the general demand for PoL power supply is 3~60A, 0.6~5.5Vdc output, 40A and above need to have PM-BUS function.
MORNSUN offers our one-stop solutions for power supplies in the bearer network application, too. Here is one of the solutions: AC/DC CRPS power supply or AC/DC open-frame converter LOF series +Telecom DC/DC converter + PoL power supply.
MORNSUN no-isolated PoL power supplies K12MT and K12DT series feature a wider input voltage range of 4.5-14VDC, adjustable output voltage range of 0.7-5.5V, current output range up to 3~120A (current sharing up to 120A); ripple/dynamic (external capacitor can meet 1%/3%), PMBus interface and black box fault recording function, and so on. They can provide high current with fast transient response for FPGA, DSP, ASIC and other high-speed chips, speeding up start-up and simplifying system-level design. At the same time, to meet the small size, cost-effective and other applications of the hidden needs.
AC/DC Main Power Supply in Optical Communication Equipment Application
The primary role of the AC/DC power supply in optical communications equipment is to provide a consistent power source to ensure system operation. In an optical communications system, equipment must operate stably over long periods of time and with high power consumption. Therefore, the AC/DC power supply must have high efficiency, stability and reliability to ensure optimal transmission quality of optical signals. When choosing an AC/DC mains power supply, in addition to the conventional parameters such as power, voltage and current of the power supply, the reliability of the power supply and its adaptability to various operating environments must also be considered. Furthermore, from the perspective of environmental and overall cost, the power supply's conversion efficiency, and power consumption are also should be paid attention.
MORNSUN offers optimal solutions for this: 15-1500W AC/DC enclosed switching power supply LM/LMF series and 120-750W AC/DC high power density power supply LOF series. The LM/LMF series features ultra-low standby power consumption, exceptional efficiency, compatibility with applications up to 5000m altitude, and a high isolation voltage of 4000VAC, making it highly suitable for use in the communications field. The LOF series is characterized by its compact size, remarkable power density and superior bandwidth efficiency, making it an ideal choice for chassis-type equipment with stringent power supply size and height requirements.
