Best Computer Networking Transceivers in 2020



Gigabit Ethernet Multi-Mode LC Fiber Media Converter (SFP SX Transceiver Included), up to 550M, 10/100/1000Base-Tx to 1000Base-SX Review:


ran 100M of fiber for lightning isolation, bought these to connect them. Laziness really, because i have sfp cages on both sides. These worked with the fiber which i basically tried to screw up the install, for months. I recently took the SFP transceivers out and put them in two different branded switches, and it works fine. I will be buying more SFP transceivers to replace these so i can experiment with running fiber.

Basically, if you want a cheap way to test fiber runs, that you can use for a long time, i think these are a good buy.

SFP to RJ45 Copper Module - 1000BASE-T Mini-GBIC Gigabit Transceiver for Cisco GLC-T/SFP-GE-T, Meraki MA-SFP-1GB-TX, Ubiquiti UF-RJ45-1G, D-Link, Supermicro, Netgear, TP-Link, Broadcom up to 100m Review:


I bought 4 of these to connect a Cisco SG200-18 switch to two other switches: Cisco-SG300-18 and Netgear GS110TP POE.
Both connections worked right away with no issues -- I powered down the switches to install the first one, but I did the second one with the switches powered up, so they are even hot-pluggable.
The Netgear switch has dedicated SFP ports, while the CISCO switch shares them with ETH ports. After installing the SFP modules both switches correctly recognized the SFP ports (they show comboF instead of comboC).
Like another reviewer pointed out, they do get hot during operation, but no more so than other electronics (for instance the cable modem, which is plastic, gets much hotter than these metal puppies), so that's a non issue for me.
I would not have spent the money for OEM parts, but this vendor is reasonably priced and thus far I am very happy with the purchase.
Will buy again from them if needed.

10G SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU2M, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, Open Switch Devices, 2m Review:


I set up an enterprise VMware environment at home for certification purposes as well as keeping my skills fresh and keeping my thumb on the pulse of technology. Doing so, a 10Gb network is a must and you need to source cables somewhere. Angry at myself for throwing out 60 or so of these cables at my job 2 years ago, I had to buy some.. and they arrived fast and definitely work great. The only thing to be aware of is that the pull tabs to release the cable don't all work properly. It's a well known fact that you sometimes have to push the cable in while pulling the tab to release it, but that trick doesn't work here. You have to use a paperclip to slide into the slot carefully release it. For that reason, and only that reason alone I have to take away a star.

10G SFP+ Cable 0.5-Meter Passive Direct Attach Copper Twinax Cable (DAC) for Cisco SFP-H10GB-CU0.5M, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, ZTE Review:


These SFP adapters are an incredible value. They spare valuable Ethernet ports to be used for network devices instead of being used as uplinks. They cost much less than an SFP GBIC and LC-LC fiber cables. While they are not available in lengths for applications much beyond links within a rack, or to adjacent racks, they fill a need for low cost SFP links between switches in a rack.

I used 2 of these to form an aggregated link between two Ubiquiti UniFi switches. I have a 48 port switch that is serving as a core switch, and an 8-port PoE switch to feed power and Ethernet to multiple UniFi WAPs.

I used two of these to form a 2gbps aggregated uplink to the PoE switch. While the link aggregation was not strictly necessary, it is nice to not have a 1gbps bottle neck for multiple 1gbps devices on the PoE switch. Plus you have the redundancy if one should fail.

Despite being listed as SFP+, these worked in the SFP ports on both switches, operating at 1gpbs (each).

HiLetgo 2pcs ESP8266 NodeMCU CP2102 ESP-12E Internet WiFi Development Board Open Source Serial Wireless Module (Pack of 2PCS) Review:


Complete project description follows. I'm using the NodeMCU as a web server and it works great. It was a struggle to find example code that actually connects outside my local area network but I found some. Also had to learn the rudiments of HTML. Only issue is it seems to need to be restarted every 4 or 5 days. Since I'm going to leave it in a remote location I'll put some code in the MEGA that sits right next to it to restart the NodeMCU every couple days, by pulling the RST pin low.

Green Pond Bridge Boat Clearance

At ‘very low tide’ the clearance under Green Pond Bridge in Cape Cod is 6’6” or less and that is too low for the boat I use. The tide charts for Falmouth, MA are theoretical and can vary as much as 18” from what is actually happening at the bridge. This system monitors the clearance and transmits the information on the internet.

All of these parts were purchased from Amazon.

Transmitter

An (Arduino) Elegoo UNO R3 board is connected to an Elegoo HC-SR04 Ultrasonic Distance Sensor. The UNO and the sensor calculate the distance from a fixed dock to the sea level, then transmit that data using a MakerFocus NRF24L01 Wireless Transceiver to the Receiver described below. The Transmitter sits on the end of a dock where there is no power, so the UNO, Transceiver and Distance Sensor are powered by the energyShield 2. This battery has special capabilities – it wakes everything up every 15 minutes. The system takes a couple readings of the distance to the water then transmits that data, then the battery shuts it all off. The data transmitted includes information from the battery – time, date, and voltage.

I have been testing this unit at home (in Dallas) and it has been operating outside, for about 20 days. Based on battery drain it looks like it will operate for about 4-5 months before it needs a recharge. When the temperature drops below zero the system still works fine but the voltage reported in the battery seems low.

All of this is housed in a plastic box printed for the purpose with a FlashForge 3d Printer Creator Pro, using eSun White ABS+ filament
Picture below.

Receiver

An (Arduino) Elegoo MEGA 2560 R3 is connected to another NRF24 Transceiver to receive the data. The MEGA does the math to convert the distance from the dock to the water, to the bridge clearance. Then the information is displayed on an Elegoo UNO R3 Touch Screen (that also works fine on the Mega).
Picture below. A small plastic frame for the Receiver was also printed on the 3d printer

Web Server

Finally, the information in the MEGA is transmitted over a serial bus to a Hiletgo ESP8266 NodeMCU ESP-12E Internet WIFI Development Board (Also operates using Arduino IDE programming). This board is connected to the MEGA via the XCSOURCE Logic Level Converter and powered by a UCEC MB102 Breadboard Power Supply Module. All mounted on an Elegoo Breadboard. The ESP8266 is programmed to be a web server. It connects to the internet through the modem/router provided by AT&T.

KeeYees 3pcs ESP8266 NodeMCU CP2102 ESP-12E WiFi Internet Development Board Wireless Module Compatible with Arduino IDE Review:


These 8266 12-5 Node-EMCU boards are a great buy for the price. These allowed me to get a few IoT projects off the ground. As I get deeper into the project I am looking into switching to the V1 8266 boards as they are smaller and would probably be more then sufficient for this project.

The Pros -
These boards are easy to set up, configure, and get working for ESP-8266 projects.
Easy to use, headers already installed.
The Cons -
The board seems with be missing a clear layout guide. The top and bottom have different pin names.
I was able to figure it out but a clearer pinout on the board would be helpful.

Over all I would recommend these boards for anyone looking to get into Ardunio and or IoT projects that require wifi.
