RJ45 Copper transceiver module Overview

Do you know about RJ45 copper transceiver module clearly? Today we will talk about RJ45 SFP/SFP+ transceiver module. RJ45 copper transceiver module is a kind of transceiver, which has been utilized as a legacy solution for some years.This article will give a clear explanation to RJ45 transceiver module,its benefits and the difference between RJ45 copper transceiver module and optical transceiver module.

1.what's the RJ45 Copper transceiver?

Copper transceiver module,also known as optical transfer copper transceiver &Photoelectric Conversion transceiver,is a kind of hot-pluggable transceiver.It supports 10/100/1000 Mbps and 10G data rates over Cat5 Cat5e Cat6 Cat6a Cat7 and Cat8 cables with RJ45 copper connector interface.And it allows communications over the twisted-pair copper cable (shielded &unshielded)of link lengths up to 100 m. So it is commonly used for transmitting data in a short distance,for instance,for server switching, LANs in data centers, for uplinks or directly to the desktop for broadband applications.In addition,with the increasing demand for high-speed communication links,RJ45 copper transceiver play a important role in the network communication nowdays.For example,10G copper SFP+ RJ45 module,which requires 10 gigabit Ethernet over Cat 6a/7 cable and offers great savings and flexibility during network deployment.

2.RJ45 Copper?Module?Features and Advantages

The battle between fiber optic SFP module and RJ45 SFP module still hot in the field of the transceiver module.Optical SFP module with LC or SC optical connectors is used in Fast Ethernet and Gigabit Ethernet allowing transmission distance up to 120km.Compared to optical SFP,RJ45 SFP module has the following advantages:

Cost-effective in Short Runs

Cost is an important factor in network deployment. When the link distance is under 100 m, choosing the copper SFP module to connect the switches might be more economical since copper SFP and Cat5e or Cat6 cables are lower-priced than optical SFP transceiver module.

Simpler Deployment

Copper SFP transceiver is convenient for operators to deploy their network systems.Copper SFP module can be plugged directly into the existing copper cabling system,which can make seamless upgrades and replacements by minimizing network disruptions.While if you choose optical transceiver, you have to tear down the existing copper cabling and redeploy the fiber cabling.You can continue to use the legacy copper cabling solution deployment or upgrade your network to save your cost once more.

Good Choice between AOCs and DACs

The interconnection between the optic network device in data center is commonly from 10M to 100M nowdays.Use RJ45 copper transceiver module can cover the shortage with SFP+ direct attach cables transmit distance.

3.Classification of RJ45 copper transceiver modules

Classify by Form factor :

SFP copper transceiver、SFP+ copper transceiver and GBIC copper transceiver modules.

Classify by transmit rate:

100Mbps copper transceiver、1000Mbps copper transceiver、(10000Mbps)10G copper transceiver and Rate self-adaption copper transceiver(integrated 10/100/1000BASE?rate on the CMOS chip,achieved the rate self-adaption)

4.What’s the difference between copper transceiver&optical transceiver?

RJ45 copper transceiver module and optical transceiver module are different from each other in actual application scenarios,but how to choose the RJ45 copper transceiver and optical transceiver depends on their advantages and disadvantages in different scenarios.Then we will talk about the difference of the two transceiver.

We will talk about the difference between copper transceiver&optical transceiver from five dimensions.

①Base on the transmission principle to distinguish

Optical transceiver transform the electrical signal to optical signal by TOSA and transform the optical signal to the electrical signal by ROSA .But the RJ45 copper transceiver only can transmit the electrical signal.

②Base on the transmission interface to distinguish

RJ45 copper transceiver use the RJ45 interface connecter,but the optical transceiver interface connecter contains LC(duplex or simplex),SC and MPO and the others interface connector which is suit for MMF transmission.

③Base on the transmission media to distinguish

RJ45 copper transceiver use the Cat5/Cat6/Cat7 patch cables to transmit the data.Optical transceiver modules use the optical fiber to transmit the data.

④Base on the transmission reach to distinguish

RJ45 copper transceiver can reach 100M in maximum,but optical transceiver can reach more than 100KM(from 100M to 160KM).

⑤Base on the parameter to distinguish

RJ45 Copper transceiver doesn’t involves to wavelength and DDM info,but most of the optical transceiver involves to these wavelength 850nm/1310nm/1550nm and the other wavelength, and DDM info.Because of the laser device which is the key parts in optical transceiver,the power dissipation of RJ45 copper transceiver is less than optical transceiver.

5.RJ45 copper transceiver application

To sum up, RJ45 copper transceiver is a cost-effective and solution for data center and cabinet wiring which is suite for the transmission distance less the 100M. In the access layer of data center,most server network NIC and storage device use the 10GBase-T RJ45 connection port,and the other side which is connect the TOR switch use SFP+ connection port usually,but they can’t connect each other straightly.Luckily,the RJ45 copper transceiver came out to solve the problem that carry out interconnect between 10G RJ45 copper interface network device and SFP+ interface switch.Below is one of the solutions for 10GBase-T optical transceiver modules for your reference.
