Difference Between Rj48 and Rj50

Registered Jacks is abbreviated as Rj, and the number is assigned as per its physical characteristics. These are first discovered by Bell Laboratories in 1973.

Registered jacks are devices that have huge applications in telecommunication that is it connect transmission local area network with the customer’s device.

 Nowadays, these cables and connectors are getting obsolete due to the increased use of wireless connections. There are many kinds of connectors with varying numbers of pins.

Rj48 vs Rj50

The main difference between Rj48 and Rj50 is that the configuration of the two connectors. The Rj48 is an 8P8C configuration, which means that the connector has 8 positions and 8 contacts.

Rj48 vs Rj50

Rj48 is a long rectangular connector with dimensions 0.3*15.6*0.63 cm and a weight of approximately 299 gm. It has copper pins, which are coated with gold to prevent rusting.

Rj50 is also a long rectangular and transparent modular connector having a dimension of 12*1.27*1.6 cm and a weight of approximately 136 gm. It has copper pins, which are coated with gold to prevent rusting.

What is Rj48?

Rj48 is a modular connector. It has an 8P8C configuration which means that this modular connector has 8 positions and 8 connection points.

It has copper pins, which are coated with gold to prevent rusting. This connector uses pins 1, 2, 4, and 5 to transmit and receive data.

These connectors are attached to cables on two ends and are used for data transfer from the provider to the consumer. The most common use of Rj48 is in T1 data lines and Local Area Networks.

This connector has 2 pins to transmit signal, 2 pins to receive signals, 2 pins for draining the signal, and the remaining 2 pins are unused.

This connector cable is more popular due to its vast use in networking. Most of the Ethernet cables have these crimped on both sides.

Main Differences Between Rj48 and Rj50

  1. Rj48 has an 8P8C configuration, whereas Rj50 has a 10P10C configuration.
  2. The contact pins of Rj48 are made of copper, and the contact pins of Rj50 are made of phosphor bronze.
  3. Rj48 can accommodate 8 wires at a time, whereas Rj50 can accommodate 10 wires at a time.
  4. Rj48 is mainly used with Shielded Twisted Pair cables (STP), whereas the Rj50 mainly accepts stranded or solid wires.
  5. It has main applications in T1 data connections, Local Area Networking (LAN), etc. and the Rj50 have its main usage in bar code system and test equipment, etc.
  6. Rj50 is costlier than Rj48.
  7. Rj48 is more popular and has a high amount of application as compared to Rj50.

Conclusion

Both these registered jacks are available in the market in both shielded and unshielded forms. These are mainly hardware items.

 But due to increases in wireless networking, their usage is going down. The data transfer through wires is faster as compared to wireless because they do not have any obstruction in their paths.

 Shielded connectors are mandatory to be used with shielded connectors. These are safer for the exposed environment.
