Most people can quickly distinguish the variations and unique usage of each cable between an RJ11 and RJ45. But it’s a bit tougher when it comes to an RJ45 and an RJ48. The modular connector is mostly the same, and the distinctions between them cannot be readily identified. RJ that stands for registered jack doesn’t indicate the type of connector used. Instead, the cables used are known. Therefore, these two forms of RJ vary only in the wired manner.
RJ45 vs RJ48
The difference between rj45 and rj48 is that RJ45 is an Ethernet network adapter where four copper wire pairs are used to signal RJ45. RJ48 is a licensed sweater, on the other hand, used for terminating T1 and ISDN. The RJ45 and RJ48 connectors and their uses are only for the people interested in the networking area.
With RJ45, a couple of configurations are available and can be used according to the situation and how. One set uses the 1,2,4, and 5 pins. There are also other wires used for additional protective purposes, while the other wires are reserved for future use. RJ45 is primarily used in networks with relatively short distances between individual network elements. The RJ45, with Cat5e, often uses the frequent UTP.
RJ48 cables are used for STP or Shielded Twisted Pair cables to maintain signal integrity. It uses 1,2,7, and 8 Unshielded Twisted Pair in categories 1 to 6. In many offices and houses, this is very typical and is the primary reason for its popularization. For other uses, RJ48 will be found most often in T1 lines of wires spanning longer lengths and often revealing themselves to the atmosphere.
Comparison Table Between RJ45 and RJ48
|Parameters of Comparison||RJ45||RJ48|
|Description||RJ45 is an Ethernet network adapter that uses four pairs of copper cables, which indicates RJ45.||RJ48 is a jack register used to terminate T1 and ISDN.|
|Number of Pins||Pin 1, 2, 3, 6 is used to receive and transfer.||Used to receive and relay pins 1, 2, 4, 5 or 1, 2, 7, and 8.|
|Cable||UTP cables||STP cables|
|Jack||RJ45 is going to match an RJ48 jack.||RJ48 jack has an additional tab to prevent the RJ48 plug from pushing into an RJ45 jack|
|Twisted pairs||Adjusts distorted pairs without shielding (UTP)||Supports twisted couple protected (STP)|
What is RJ45?
It is possibly the most common kind of connector among Ethernet cable connectors. The rectangular method is a long one with a diameter of 11.69 mm—clear acrylic, rigid and long-lasting. You can see the exact relation between the wires with the search feature. The Rj45 has 8P8C, which has eight distinct locations and eight points of reference. This connector is positioned in just one form. The cables are placed 1, 2, 3, and 6.
It is fitted with eight copper pins. They serve as drivers that relay drives from the router to the wire, vice versa. Gold is used to treat the surface of the pins to avoid rusting. The aesthetic benefit of the connector is further enhanced. It is suitable for unbroken (UTP) and local area network links. It has a tweaked Twisted Pair cable between copper wires and the outer PVC jacket without a foil cover. This connector is also suitable for cables that needn’t be too long to connect indoors.

What is RJ48?
This connector form is not as popular as Rj45. But it has very similar features, making it difficult to distinguish them without carefully looking at them. The Rj45 is also constructed from stiff transparent plastic, allowing the attachment between wires to be visible inside. Like the Rj45, it has an 8P8C setup, which enables it to handle eight wires simultaneously. Interestingly, this connector has two types of placement. The first one is a sequence of 1, 2, 3, and 6. The second follows a pattern of 1, 2, 7, and 8. The Rj48 is also more robust than the Rj45.
The connector has copper pins which serve as conductors between the cable and the source of the network. They are gold-coated to avoid rusting them. The Rj48 is an ideal connector for cables that are often ideal for outdoor use with STP (Shielded Twisted Pair). The cables feature an additional cover between the copper wires and the outer PVC jacket.

Main Differences Between RJ45 and RJ48
- Unbroken tweeted pairs (UTP) are used by the RJ45, whereas shielded twisted pairs are used in the RJ48 (STP). The two types of wires are covered with PVC to prevent electrical damage from the transmission of data. The additional foil coating is provided by the STP cables. For longer cables and cables exposed to the weather, STP cabling is needed in which the possibility of data integrity is impaired.
- As you see the two together, you can know that the RJ45 jack is widely used as Ethernet connectors. It was used once but no longer for specific extensive telephone networks. It is now used to bind computers. In contrast, the RJ48 is widely used for T1 lines and other applications requiring long cables which can be environmentally exposed. Due to the inclusion of security provided by the STP cable, RJ48 is best suited to that.
- Rj45 is a Single row line, whereas rj48 is a Multi-line and flush assembly.
- Pins 1,2,3, and 6 are available in RJ45 connectors, whereas several pin groupings of RJ48 connectors are used. Some of them are 1, 2, 4 or 5, or 1, 2, 7, or 8. Additional data shielding can also be used on other cables.
- There is an ‘8’ position in rj45, whereas a ’10’ position in rj48.
Both the Rj45 and Rj48 connectors are essential. They guarantee an easy and effective connection between your devices and network sources. They have many similar features, but they also have different characteristics which distinguish them.
Verdict: Who’s bigger, then – Rj45 or Rj48? All these connectors are fine and have certain similarities. It is straightforward. The Rj48 appears, however, to be the one with two cabling processes, making it more polyvalent than the Rj45. It is also capable of linking STP cables and has no issue with long cables.
