Each of our machines offer flexibility in production requirements and are programmable to meet and exceed standard requirements for modular connector production.

For gold-plating, our strict quality control specifications rules that proper gold plating thickness is followed (range of 6 to 50u”) to ensure high reliability of data transfer.

Thus, whenever you require OEM services, we are capable of producing your demand at a very low cost.



As there is the much needed requirement for RJ45 connectors to transmit high data speeds over copper cables in Ethernet wiring systems, Otscable has a proven method of minimizing network signal issues


Generally, we strictly follow the circuitry to accommodate the standard RJ45 pinout diagram. Added to this, our company has developed a number of modernized methods for achieving high Gigabit demands. Thus, with the collective RF propagation methods done on the RJ45 connector interface, EMI/RFI interference issues are greatly minimized. 

You can ensure that our RJ45 connectors can deliver signals at an enhanced level and shield effectiveness and crosstalk characteristics are improved.

Quality Control

All our RJ45 connectors are manufactured with compliance to ETL and UL listing, as we place a high priority to quality control. Our products are bearing CE markings; moreover, we also meet the compliance for the ANSI/TIA-568 C.2 requirements. 

For manufacturing patch cables with RJ45 terminations, we make sure that each cable connection went through cable testers/fluke testing to verify the continuity of the cables.

Our connectors are made with non-toxic, dust-free, and reliable process, which meets RoHS and LSZH standards. We comply with stringent standards for environmental and international policies. Because we do not use solder, there is no lead (Pb) emissions during manufacturing.

FAQs about RJ45 Connectors

What is an RJ45 connector?

The “RJ” in RJ45 connectors stand for “registered jack”. It is a standard twisted-pair plastic connector with an 8 position 8 contact (8P8C) configuration for Ethernet devices. In RJ45 connections, the “plug” is the male end of a connection, while the “jack” is the female connector. Modular connectors such as RJ45 are heavily used in wired Ethernet connections.

Each modular connector has 8 wires with different colors – 4 solid colors and 4 striped colors. There are two standard RJ45 pinouts defined by the TIA/EIA-568. These are T568A and T568B standards. Each standard has a color code diagram as enumerated below.

What types of cabling commonly uses RJ45 connectors?

A type of cable called a “twisted-pair” of cable uses RJ45 connectors. This is commonly used in LAN wirings and telephone lines. This cable has four twisted pairs. The reason why the wires are twisted is to eliminate crosstalk and interference. 

How many pin positions does an RJ45 plug have?

Each RJ45 connector has eight pins, which means that each LAN cable contains eight separate wires.

How do you wire an RJ45?

RJ45 connectors can be wired in two ways: straight through (EIA/TIA 568B) or crossover (EIA/TIA 568A).


#1 Straight through RJ45 Pinout and wiring – EIA/TIA 568B Standard

This is the most common method of wiring RJ45 cables. As the name implies, each wire is run through a straight line before crimping with an RJ45 connector. 

This configuration is typically used in 10Base-T and 100Base-Tx network hubs.

#2 The crossover RJ45 network cable, EIA/TIA 568A

Ethernet crossover RJ45 cables are used in small LAN network systems where only a limited number of computers are connected (for example, only two computers). This wiring system for RJ45 is also used when there are only two hubs are connected for increasing nodes in a network. 

How to crimp an RJ45 for Cat5e and Cat6 according to the EIA/TIA 568B standard?

#1: Preparing a network cable

First is to slide the snagless boot on the cable. Strip off the cable jacket at about 1 inch from its end using a crimping tool.

#2: Follow the wiring diagram

Un-twist each 4 pairs of wires inside the cable by hand. Arrange the conductor wires according to the 568B standard.

*The RJ45 termination for Cat5 and Cat6 cables are the same but in some cases, Cat6 and above categories uses a load bar to efficiently separate each wire. The load bar aligns each wire with its designated pin. This way, crosstalk between the wires can be eliminated.

Step #3: Insert the wires in the RJ45 connector

Insert the wires according to its proper order inside the RJ45 connector. Make sure that the gold pins “bite” the wires.

Step #4: Crimp the Connector and Cable into Place

Crimp the cable and connector into place to secure the connection. 

Here is a video on how to crimp an RJ45.
