Can 10Gb Switch Port Link to Gigabit Switch Port?

With the tendency for higher speed network, 10Gb switch has already become familiar with home individuals, no longer the privilege of enterprise operators. However, the issue of SFP to SFP+ compatibility always puzzles many network switch users, even some engineers. Will 1Gb SFP transceivers work with 10Gb SFP+ ports on 10Gb switch? Or will 10Gb SFP+ run at 1Gb to link gigabit switch? And If 10Gb optics in a switch can auto-negotiate to 1Gb when the other end is 1Gb? All these related questions origin from the link between 10Gb SFP+ slots on 10Gb switch and 1Gb SFP ports on gigabit switch. Thus this article will reveal the mask of SFP to SFP+ compatibility from this point of view.

10G SFP+ Port on 10Gb Switch Take 1G SFP Optics on Gigabit Switch in Most Situations

Will 1Gb SFP transceivers/modules work with 10Gb SFP+ ports? The answer is “Yes” in most cases. There are many vendors providing 10Gb switches that can take both a 10G SFP+ and a 1G SFP in the 10Gb SFP+ slot, but not at the same time for obvious reasons. This option is supported by dual speed operation. So before plugging a SFP transceiver into the SFP+ port on your 10GbE switch, one must consult your rep to make sure the 10Gb switch port support dual speed.

To achieve link of 10Gb switch port to gigabit switch port, here is a simple guide. Install a 1Gb SFP module on the 10GbE switch SFP+ port and the gigabit switch 1Gb SFP port respectively, then connect the 10Gb switch and the gigabit switch with corresponding 1Gb SFP fiber cable or Ethernet copper cable (eg. Cat6).

1G SFP Port on Gigabit Switch Cannot Take 10Gb SFP+ Optics on 10Gb Switch in All Cases

Will 10Gb SFP+ running at 1Gb? The answer is definitely “No”. SFP optics do work in SFP+ slots in most cases, but SFP+ optics on 10Gb switch can never work in SFP slots on gigabit switch. The reason is about a power availability thing. As we know, once an module is installed, the speed of the port is decided. Most SFP+ slots are backward compatible with SFP modules to run at 1G speed. However, the SFP slots on gigabit switch cannot support the 10G speed required by SFP+ modules. For instance, most Cisco and FS 10Gb switches support 10G SFP+ and 1G SFP optics on their SFP+ ports. But some Brocade gear and HP A-series models are SFP+ only. One need to double check the compatibility of this switch with the vendor rep.

FS 10Gb switch SFP+ port link to gigabit switch SFP port

FS 10Gb switch SFP+ port links to gigabit switch SFP port via 1G SFP modules and fiber patch cable.

SFP+ Optics in a 10Gb Switch Cannot Auto-negotiate Down to 1G when the Other End Is Gigabit Switch

Unlike copper SFP modules supporting 10/100/1000 auto-sensing, fiber optics do not support auto-negotiation. Because this technology is based on electrical pluses but not optical pluses. Thus 10Gb SFP+ optics on 10Gb switch can not auto-negotiate down to 1Gb if the other end is gigabit switch. In fact, most SFP and SFP+ transceivers only run at its rated speed and the transceivers at both end of the cable should at the same speed. For example, if a 10Gb SFP+ module is plugged into the 10Gb switch port, it will only run at 10Gb. In this case if you link it to the gigabit switch port, it will not work. When sticking a 1Gb SFP module in the 10G SFP+ port, the 10Gb switch will only run at 1Gb. As thus you can link it to gigabit switch.

Sometimes the 10GbE switch port would lock the speed at 1G until you reconfigure the switch to 10G. It is noted that SFP+ port usually enables a speed under 1G, which means one cannot insert 100Base SFP modules into SFP+ ports on 10Gb switch.

Conclusion

For the issue of SFP to SFP+ compatibility, a simple response is that most SFP+ can take SFP but not vice versa. The uncertain situation requires one to ask their switch vendors for clear reply. Thus 10Gb switch port is possible to link to gigabit switch port to run at 1G speed. The only thing you need to do is to plug each the aforesaid port with a 1Gb SFP module, and then connect the two modules on the 10Gb switch and the gigabit switch with a corresponding fiber patch cable or Ethernet copper cable.

Buy Gigabit Switch: 2 x 24 Port Switch or 1 x 48 Port Switch

As for the issue of Gigabit network setups for more than 24 connections, we usually stick in the dilemma of choosing from different scenarios of Gigabit switch: deploying 2 x 24 port switch or 1 x 48 port switch, which one to take? We are here to weight their pros and cons for your selection guide.

Gigabit Switch: 2 x 24 Port Switch or 1 x 48 Port Switch Overview

Budget is always a big concern before touching other factors. It is somehow a common sense that buying 2 x 24 port switch costs less than a 48 port switch. Thus many people go for 2 x 24 port switch for cost savings. In fact, that’s not always the same case. For example, buying one S3800-48T4S 48 port switch ($499.00) will save you over 200 dollars than two S3800-24T4S 24 port switch ($369.00) from FS.COM. For people pursuing high performance but with tight budget, just go for FS S3800-48T4S 48 port switch, which best satisfies your dual demands.

2 x 24 Port Switch Solution Pros and Cons

For concerning about 2 x 24 port switch solution, one should know its pros and cons. First, having 2 x 24 port switches gives you more sense of security. If one switch goes down, users in another switch will still be running. However the collapse of the sole 48 port switch will lead to the whole network’s breakdown. Second, 2 x 24 port switch solution provides more flexibility for separate placing. If you need to connect different devices in different floors or offices, 2 x 24 port switch is the way to go. However, it is noted that this solution has the cons of higher potential bottleneck, less available ports, extra uplink port demand, space consumption and management inconvenience.

1 x 48 Port Switch Solution Pros and Cons

Apart from the cost-efficiency of 1 x 48 port switch offered by FS.COM, there are other cases 1 x 48 port switch is preferred. First, 48 port switch is natural for high-performance network environments. In 2 x 24 port switch solution, due to one extra uplink port for connecting the 2 switches, a potential bottleneck/congestion is created and only 46 ports are left available for devices. So in cases only one uplink is available, 48 port switch is the choice. Second, 48 port switch has the pros of ease of management and rackspace saving even if 2 x 24 port switches are stacked. Third, one 48 port switch costs less power than the 2 x 24 port switch strategy. However, this solution will lose the redundancy for network outages and separate placing flexibility.

Gigabit Switch: 2 x 24 Port Switch or 1 x 48 Port Switch Selection Guide

After explaining the two solutions respectively, we made the following conclusion. For most concerns about performance, one should go for 1 x 48 port switch, which owns lower potential congestion at the uplink port and can travel at the wire speed. For concerns of space saving, management convenience and more port numbers, also go for the same way. But in terms of redundancy and separate placing, one should better take 2 x 24 port switch.

Table below lists the edges for selecting one solution over the other.

Solution 2 x 24 Port Switch 1 x 48 Port Switch
Edges over the other Redundancy: one more backup switch in network outages High performance: wire speed; power saving; less potential congestion
Separate placing: different floors or offices More available ports: saving extra uplink for connecting two switches
Generally less cost Rackspace saving; Ease of management

In some cases requiring for special conditions, pay attention to their built-in features. For instance, in quiet places such as classrooms, take fanless 24 port switches because 1 x 48 port switch can be noisy due to equipped fan radiator.

Conclusion

For Gigabit switch: 2 x 24 port switch or 1 x 48 port switch, it’s extremism to simply say which one is superior or inferior. We decide which to buy by the factors we are most concerned about and the respective edges over the other in each case. No matter you need 24 port switch or 48 port switch, FS.COM would be a good place to go.

24-Port Switch Selection: Which Is the Suitable Choice?

An Ethernet switch acts as a bridge to connect different parts of a network together. Although many routers also possess the network switching capabilities and multiple Ethernet ports, the Ethernet switch is not the replacement for routers. It is worth emphasizing that Ethernet switches are smarter than routers in that they operate at the data link layer (Layer 2) and the network layer (Layer 3) of the OSI Reference Model and therefore support any packet protocol. Ideally, switches will make better use of bandwidth if you prefer wired to wireless connections but have more devices than available Ethernet ports. On the other hand, an Ethernet switch is a costly way to expend the network in home or small business. So it is very important to invest an Ethernet switch with the appropriate number of ports to fit your needs. In the midst of various Gigabit Ethernet switches, a 24-port switch is considered as the most common Gigabit switch that connect devices in a local area network. Then this article will explore how to select a suitable 24-port switch.
