The UGREEN CM648 (25051) is a USB-A 3.0 to RJ45 2.5GbE Ethernet adapter designed to add high-speed wired network connectivity to compatible computers. It supports 10/100/1000/2500Mbps Ethernet connections through a USB 3.0 host interface.
Featuring a Realtek RTL8156BG network controller and compact aluminum housing, this adapter is useful for NAS access, file transfers and office networking. Check the latest UGREEN CM648 (25051) price in Bangladesh at IT Source.
The UGREEN CM648 converts a compatible USB-A computer connection into a 2.5GbE RJ45 network interface. It allows supported computers to connect to multi-gigabit networks without installing an internal Ethernet card.
Its Realtek RTL8156BG controller supports Ethernet link rates of 10Mbps, 100Mbps, 1000Mbps and 2500Mbps. The adapter automatically negotiates a compatible speed with connected network equipment.
The aluminum enclosure and integrated USB-A cable make the adapter practical for everyday workstations. It draws power from the computer's USB port and does not require a separate power adapter.
The CM648 supports a maximum RJ45 Ethernet link rate of 2.5Gbps, offering higher network capacity than conventional Gigabit Ethernet adapters.
It is useful for transferring large files, accessing network storage and working on high-bandwidth local networks. Full performance requires compatible 2.5GbE network equipment and suitable cabling.
The adapter uses the Realtek RTL8156BG chipset for USB-to-Ethernet communication. It supports multi-speed Ethernet operation and automatic network link negotiation.
When connected to a slower Gigabit or Fast Ethernet network, the adapter operates at a supported lower link rate. Actual throughput depends on the network path and connected equipment.
The integrated USB-A 3.0 connector supports theoretical host bandwidth up to 5Gbps, providing sufficient interface capacity for the adapter's 2.5GbE networking function.
Connect the adapter to a USB 3.0 port for maximum performance. Older USB 2.0 connections may work at reduced speeds due to their lower bandwidth.
The CM648 supports 10/100/1000/2500Mbps Ethernet links. It can therefore connect to existing compatible 100Mbps and Gigabit networks as well as upgraded 2.5GbE environments.
The Ethernet link rate does not guarantee an equivalent internet speed. Actual internet performance depends on the service provider, router, network load and remote server.
The adapter features a compact aluminum enclosure and an integrated USB-A cable. Its portable design is suitable for laptop bags, office desks and desktop workstations.
RJ45 network status indicators help identify network connection and activity. The adapter receives operating power directly from USB and does not require external power.
The CM648 supports compatible Windows and macOS computers, with Linux driver availability depending on the operating system and kernel version. Windows 11 and supported macOS systems may recognize the adapter without manual driver installation.
Other Windows or Linux configurations may require a compatible Realtek driver. Confirm operating system support and USB-A host compatibility before purchase.
