There are a few differences that may help in your decision between flared and slot ports for your custom subwoofer box. Flared ports are very good at virtually eliminating port noise. Port noise is the noise created by the friction of air moving through the port. The x800s also have built-in WIC slots. So if a 2 port serial card is inserted into the first built-in WIC slot, the interfaces are number Se0/0/0 and Se0/0/1. If the second built-in WIC slot is populated with the same 2 port serial card, the numbering is Se0/1/0 and Se0/1/1. The next slot available on an x800 would be the first network module. Joel dirt is completely right. To put it short, slot ports are only superior beucause you can make the port area to your satisfaction, and bed it so its longer. However, round ports can also easily be made into an 'L' or labrynth shape, just no one does it. CLICK to View Plan Sample.UPDATED. Fiberglassed 7 inch Monitor Mount Work Log. Identifying the USB 3.0 port on your Laptop / Computer. If you have a USB 3.0 port on your system, it’s good to be aware which port will give you the better performance. There are two main ways by which you can’t identify your USB 3.0 port: by the logo and by the port color. USB 3.0 was also marketed as SuperSpeed USB. For example, the end of a USB cable has a connector that allows it to connect to a USB port. The port has either holes or a slot that matches the plug or card connected to the port. The picture is a computer PS/2 port for a keyboard and mouse with a PS/2 connector to connect to the computer.

In Gigabit Ethernet applications, either SFP port, RJ45 port or GBIC port is used in different Gigabit devices, such as switches, routers, servers and storages. And some latest wireless access points (APs) are also equipped with SFP port. Since all these three port types only support 1Gbit and do not go any higher, why are they created instead of using only one type?

SFP Port vs. GBIC Port: An Improvement in Dimension

SFP port and GBIC port can be found in a variety of equipment, including Ethernet switches, routers, network interface cards, servers, etc. Today most Ethernet switches are designed with as least one or two Gigabit SFP uplink slots. What is SFP port? As the name implies, SFP port is intended for taking in SFP (mini-GBIC) fiber modules with small form-factor (SFF) connectors, while GBIC port is for accepting GBIC modules.

The two types of ports can provide the same data rates and same distances in Gigabit applications, but the same number of SFP ports uses less space than that of GBIC ports. Since they have the equal functionality, SFP has gradually taken the place of the older GBIC in Gigabit networking for space-saving and economical reasons. The table below is a comparison of SFP port vs. GBIC port.

SFP vs. RJ45 port: Distance Makes Difference

The RJ45 ports in Gigabit networking devices follow the 1000BASE-T Ethernet standard. They only support twisted pairs for network connections, and the distance is limited to 100 m (330 feet). RJ45 port uses Category 5/5e/6 and higher level copper Ethernet cables for 1Gbit transmission. Compared with switch using only RJ45 port, SFP port switch supports more types of communication cables and longer reaches of links. Here are the differences between SFP vs. RJ45 port.

Since most end-points at the customer’s are still using RJ45 port, in order to retaining the convenience of RJ45 port while providing the advantage of SFP network to customers, some switches include combo SFP/RJ45 ports. So users can choose to utilize either the SFP port or the RJ45 port at a time for short-distance connections.

What Is Dual-Rate SFP Port?

Unlike the combo SFP/RJ45 port which is actually a link shared by two different ports, a dual-rate SFP port is one single SFP slot that can be configured to support two different data rates. Generally a dual-rate SFP slot can set to be either 1G mode or 10G mode, i.e., an SFP module or an SFP+ module can be installed in it. But the actual data rate of the transmission depends on the mode being settled and the transceiver module being used. There are several cases:

• The dual-rate SFP slot is 10G activated, and an SFP+ module is installed; the interface is in 10G mode.
• The port is 10G activated, but an SFP module is installed; the interface is in 1G mode.
• The port is not 10G activated, but an SFP+ module is installed; the interface will be link down state.
• The port is not 10G activated, and an SFP module is installed; the interface is in 1G mode.

Summary

Difference Between Slot And Port Replicator

The three port types—SFP port, RJ45 port and GBIC port—are used in different networking equipment. The SFP port is now more commonly used than GBIC port since the former one provides the same function and is more compact. When SFP port vs. RJ45 port, SFP port supports connectivity through varieties of fiber cables and the copper twisted pairs, and a wide range of link distances, but RJ45 port accepts only twisted pair cables and a shorter distance. Since every thing has both two sides, it is not always the best to choose SFP slot. The two articles: GBIC vs SFP: When It’s Best to Use GBIC and When to Use SFP, and RJ45 vs SFP: Which Should I Use to Connect Two Switches, specifically discussed when to use which port/module type.
