by Fiber-MART.COM

With the development of smart home and small and medium-sized businesses (SMBs), there is a growing adoption of PoE devices like IP cameras, VoIP phone, wireless access points (WAP), IoT devices, etc. Therefore, network switches are required to be able to support numbers of PoE installations, which brings 48-port PoE switch into the market. Then how to choose a suitable 48-port gigabit PoE switch for PoE applications? What are the most considered factors to buy a PoE switch? In this article, these questions will be answered in details.

 

What to Consider When Choosing a 48-Port PoE Switch?

As we know, PoE switch, offering both data and power for PoE-enabled devices, is an important component for connection with PoE. To meet network deployment requirements, 48-port PoE switch now is a popular option for network builders. Then from users front, what elements do users consider?

Power Budget

Power budget is an essential factor that most users will consider when buying a PoE switch. According to the explanation on Wikipedia, the PoE standard (IEEE802.3af) provides up to 15.4W of DC power on each port theoretically, while the PoE+ standard (IEEE802.3at) can offer up to 30W per port, but only 25.5W could transmit to network devices in real time. However, in real time, not every port requires the 30W. Most are still under the 15W range. Therefore, maximum power of each port and how many ports of the switch supporting PoE should be taken into consideration to ensure the device can get enough power.

 

Acoustic Noise

Noise caused by the PoE switch fan is a troubling problem for many users. Though there is fanless PoE switch like 8-port PoE switches, the capacity of them cannot satisfy users’ demand. Since many of them want to use the high density 48-port PoE switch in office or even at home, while the noise from the PoE switch is so disturbing. Therefore, the degree of noise caused by the PoE switch is also a parameter that many users care about.

 

Cost

48-port PoE switch price is always a hot topic that users care about. For there are various sellers online providing diverse brands of PoE switches, the price of the 48-port switch is also changeable. For example, the Cisco 48-port PoE switch price is $2666, and the HP PoE gigabit switch with 48 ports (J9853A) is $4789. While the price of fiber-mart.COM 48-port PoE gigabit switch is $689. These different prices allow users have more choices to select the suitable one for their networks.

 

Manufacturer or Warranty

Similar to the cost, there are numbers of manufacturers who can produce PoE switch. And they have many small agencies that selling their switches. Though the switch price may low, the warranty of the switches cannot be ensured. Nearly all brand manufacturers have claimed that their lifetime support is restricted to authorized sellers. Therefore, when choosing a needed 48-port PoE switch, make sure that the seller is reliable.

 

Recommendations for Popular 48-Port PoE Switches in the Market

To further illustrate all the factors mentioned above on choosing a suitable 48-port PoE switch, here is a simple comparison between popular 48-port PoE switches in the market.

 

From the chart, we can see that the capacity and price of these 48-port PoE switches vary from vendor to vendor. In comparison, fiber-mart.COM S1600-48T4S PoE switch offers four SFP+ ports for high-capacity uplinks, which allows users connect to a high-performance storage server directly or deploy a long-distance uplink to another switch. And its price is its another great advantage among these PoE switches. Cisco and HP 48-port PoE switch requires users invest relatively high cost, but it’s a good choice if users have strict requirements for acoustic noise.

 

48-port PoE switch with SFP+ port enables network designers to achieve high-performance and long distance network deployments. Power consumption, acoustic noise and manufacturers are what the users should consider when choosing a PoE switches. After all, nobody can make bricks without straw. Choosing a reliable manufacturer like fiber-mart.COM who can provide networking solutions for data centers and enterprise networks is also important.

Fiber Optic Cable are usually used in two scenarios

Fiber Optic Cable are used in applications where the optical signal is too strong and needs to be reduced. For example, in a multi-wavelength fiber optic system, you need to equalize the optical channel strength so that all the channels have similar power levels. This means to reduce stronger channels’ powers to match lower power channels.

The attenuation level is fixed at 5 dB, which means it reduces the optical power by 5dB. This attenuator has a short piece of fiber with metal ion doping that provides the specified attenuation.

There are many different mechanisms to reduce the optical power, this picture shows another mechanism used in one type of variable attenuator. Here variable means the attenuation level can be adjusted, for example, it could be from 1 dB up to 20dB.

Fiber Optic Cable are usually used in two scenarios.

The first case is in fiber optic power level testing. Cable are used to temporarily add a calibrated amount of signal loss in order to test the power level margins in a fiber optic communication system.

In the second case, Cable are permanently installed in a fiber optic communication link to properly match transmitter and receiver optical signal levels.

Optical Cable are typically classified as fixed or variable Cable.

Fixed Cable have a fixed optical power reduction number, such as 1dB, 5dB, 10dB, etc.

Variable Cable’ attenuation level can be adjusted, such as from 0.5 dB to 20dB, or even 50dB. Some variable Cable have very fine resolution, such as 0.1dB, or even 0.01dB.

This slide shows many different optical attenuator designs.

The female to female fixed Cable work like a regular adapter. But instead of minimizing insertion loss, it purposely adds some attenuation.

The female to female variable Cable are adjustable by turning a nut in the middle. The nut adjusts the air gap in the middle to achieve different attenuation levels.

The male to female fixed Cable work as fiber connectors, you can just plug in your existing fiber connector to its female side.

The in-line patch cable type variable Cable work as regular patch cables, but your can adjust its attenuation level by turning the screw.

For precise testing purposes, engineers have also designed instrument type variable Cable. These instrument type Cable have high attenuation ranges, such as from 0.5 dB to 70dB. They also have very fine resolution, such as 0.01dB. This is critical for accurate testing.
