CAT 3 إيثرنت, also known as Category 3 Ethernet or Cat 3, is a type of Ethernet cable used for network connections. It was widely used in the 1990s and early 2000s and has been largely replaced by higher category cables. في هذه المقالة, we will explore the details of CAT 3 Ethernet and its applications.
Overview of CAT 3 إيثرنت
——–
1. تعريف
– CAT 3 Ethernet is a type of twisted pair cable that consists of four pairs of 24-gauge copper wire.
– It is characterized by its ability to transmit data at a maximum frequency of 16 MHz.
– CAT 3 Ethernet cables typically use an RJ-45 connector for connection.
2. التطبيقات
– CAT 3 Ethernet is mainly used for voice and data communication over short distances.
– It was commonly used in residential and small office settings for telephone and internet connections.
– It can support data rates up to 10 Mbps and is compatible with Ethernet, Fast Ethernet, and Token Ring networks.
Advantages of CAT 3 إيثرنت
——–
1. Cost-effective
– CAT 3 Ethernet cables are less expensive compared to higher category cables such as CAT 5e or CAT 6.
– This makes them a cost-effective choice for low-bandwidth applications or when upgrading from older technology.
2. التوافق
– CAT 3 Ethernet cables are compatible with most Ethernet devices and networking equipment.
– They can be used to connect computers, أجهزة التوجيه, switches, and other network devices.
Disadvantages of CAT 3 إيثرنت
——–
1. Limited bandwidth
– CAT 3 Ethernet has a limited bandwidth of 16 MHz, which restricts its data transmission capacity.
– It is not suitable for high-bandwidth applications such as video streaming or large file transfers.
2. Limited distance
– CAT 3 Ethernet cables have a limited transmission distance of up to 100 meters (328 feet).
– Beyond this distance, signal degradation and loss may occur.
