How to Choose SFP Transceiver Modules for UniFi US-8-150W Switch?

Ubiquiti Networks Unifi switch is part of the UniFi line of products that delivers robust performance and intelligent switching for the growing networks. Many customers nowadays hold great feedback about the cost-effective UniFi switches. US-8-150W, as one of the most popular UniFi switches, offers eight Gigabit RJ45 ports and 2 SFP ports that can support up to 1Gbps. So, how to choose the suitable optics for UniFi US-8-150W switch? This article will provide detailed information about this UniFi switch and the appropriate SFP modules for US-8-150W switch (seen in the below image).

Understanding UniFi US-8-150W Switches

Ubiquiti Networks UniFi switches can be divided into two types: managed Gigabit switches and managed PoE+ Gigabit Switches. In short, POE switches and non-POE switches. Each UniFi switch type is fully managed Gigabit switches with RJ45 and SFP+/SFP ports, offering non-blocking throughout switching performance.

US-8-150W UniFi switch features 8 RJ45 ports and 2 SFP ports which offer convenient different power output options, auto-sensing IEEE 802.3af/at POE/POE + performance. It is a bit larger than a standard home switch. So, would-be buyers who are looking to rack mount need to buy a extra shelf and stick it there. The table below provides the clearer information about this switch.

Note that US-8-150W is only US $199.

How to Select SFP Modules for UniFi US-8-150W Switches?

According to Ubiquiti Networks, both their original and third party SFP transceiver modules from other vendors can be used on UniFi switches.

Ubiquiti Networks UF-MM-1G & UF-SM-1G-S

Ubiquiti Networks only offer two type of SFPs—UF-MM-1G and UF-SM-1G-S. UF-MM-1G SFP module supports a data rate of 1.25 Gbps over multimode fibers. It uses the 850nm as the Tx and Rx wavelength with a supporting distance of 550m.

UF-SM-1G-S is a single-mode SFP available in both blue (1310nm) and yellow (1550nm) color code. Unlike the 1000BASE-LX SFP optics with LC single-mode fibers that can operate up to 5 km, UF-SM-1G-S only supports a link limit of 3 km.

Figure 3 presents all the existing fiber optic transceivers (SFP and SFP+) from Ubiquiti Networks. UF-SM-1G-S is in the middle of the image.

3rd Party SFPs for US-8-150W Switch

Besides the above two SFP types, there are several more Gigabit Ethernet standards for SFP transceiver modules—1000BASE-T, 1000BASE-SX, 1000Base-LX/LH, 1000BASE-ZX, 1000BASE-BX-D, 1000BASE-BX-U and 1000BASE-EX, which are compatible with the UniFi switches. According to the Ubiquiti Networks, Fiberstore (FS.COM) SFPs are tested to be fully compliant with UniFi switches. For more information about these compatible SFPs, please check on the following list.

From the table, we know that several Cisco SFP modules and HPE SFP transceivers are working on the UniFi Switches. In our test center, we have tested the GLC-T compatibility and Cisco GLC-SX-MM compatible issues.

More Information About UniFi Switches

Besides the hot selling US-8-150W switches, there are a series of UniFi switches such as US-8-60W, US-16-XG, US-48, US-8, US-24, US-48-750W, US-48-500W, US-24-250W, US-24-500W. Whether you use which one, FS.COM SFPs in the above table are tested to be fully compatible with UniFi switches. For such a low price of the 3rd party SFP transceiver modules, it is advisable for you to purchase more optics for backup.

Summary

The UniFi US-8-150W switches are designed to be part of the complete line of small business or home networking and wireless communication products that work together as part of proven, fully integrated, easy-to-use small business solution. UniFi switches support several types of Gigabit Ethernet SFP optical transceivers. All these high-quality fiber optic transceivers can be found on FS.COM for great prices. We also make sure to provide its customers same day shipping. Some of the items can be directly shipped from Seattle warehouse.

C3KX-NM-10G Network Module Overview

Questions like whether a 1G SFP can be used on the SFP+ port of the switch and support 10G data rate are frequently asked by overall users. Generally, you will get the answer “no”. Because Most (95+%) SFPs and SFP+s will only run at the rated speed, no more, no less. Even though SFP and SFP+ have the same port size, it doesn’t mean that you can insert a SFP in a SFP+ port to achieve a 10G connectivity. Not to mention that some SFP+ port can only support 10G SFP+ optics. However, this article will introduce a Cisco Network module in Cisco Catalyst 3750-X and 3650-X Series switches that can both support 1 GbE SFP and 10 GbE SFP+ transceivers.

C3KX-NM-10G Network Module

The Cisco Catalyst 3750-X and 3560-X series switches support four optional network modules for uplink ports, namely C3KX-NM-1G (four GbE port network module), C3KX-NM-10G (two 10GbE SFP+ ports network module with four physical ports with two SFP+ and two regular SFP ports), C3KX-NM-10GT (two 10GB-T ports network module), C3KX-SM-10G (service module with two 10GbE SFP+ ports network module for Netflow and MACsec encryption). C3KX-NM-10G module on the Cisco Catalyst 3750-X and 3560-X has two installation screws on each side, which make it easy to switch things out and make new connection without a fuss. What’s more, when business demands changes, the C3KX-NM-10G network module allows customers to only upgrade their modules from 1 GbE to 10 GbE without replacing a comprehensive upgrade of switch.

As the above image shows, the C3KX-NM-10G network module has four slots—two SFP+ slots and two SFP slots. These four slots usually work in pair, with one pair supporting 1 GbE data rate and the other achieving 10 GbE. Note that you must use the same form factor transceiver in a pair and never mix the SFP module with SFP+ module. SFP+ can’t auto-negotiate down to 1G to support with SFP module.

To put it simply, let’s name the port from left to right as slot 1, slot 2, slot 3, slot 4. Usually a 10-Gigabit SFP+ module takes precedence over a 1-Gigabit SFP module. But it’s another case when an SFP module is first inserted in Slot 1 and has link. For example, if the SFP in Slot 1 retains link, you insert an SFP+ module in Slot 2 and it will not operate. If the SFP module in Slot 1 is shut down or removed, the SFP+ module in Slot 2 turns on. The SFP module in Slot 1 does not work as long as an SFP+ module is in Slot 2. The following chart concludes the accessible combination of SFP and SFP+ modules.

Suitable Cisco Transceivers for C3KX-NM-10G Network Module

As note before, C3KX-NM-10G module on the Cisco Catalyst 3750-X or 3560-X series switch can both support 1 Gigabit Ethernet and 10 Gigabit Ethernet data links. We will list the available Cisco modules attached with detailed information in the below charts.
