Cheap FE1.1s USB 2.0 Active Extension Repeater Cable for DMM data logging

[Kiriakos GR]

This is the third article in favor of USB 2.0 Active Extension Repeater Cable.

Terminus FE1.1s this is the Low End budget Chip, in contrast to Terminus FE1.1 High end.

It appears speaking of product availability:
80% of budget cables they use Terminus FE1.1s Chip
While solutions using Terminus FE1.1 they are just three or four worldwide.

Long story in sort, DMM data logging due USB to IR ( dedicated accessory), this is not that demanding application, regarding bandwidth.
And Terminus FE1.1s this supporting single transaction handling in the unit of time, this cannot be overloaded.

Single transaction handling in the unit of time

DMM data logging, this is considered as Single transaction handling, and therefore all cheap active extensions will work.

The problem with Low End active USB cables:
a ) They are sold by ghost brands unbranded
b ) The cable this can be of lowest quality, this not tolerating abuse in contrast to a permanently installed cable.
c ) The cable does not have AWG markings, it might use lowest quality of copper alloy.
d ) You cannot use this cable in a wide range of applications
e ) THE PRICE ...  while you may find lengths from 5m to 20m (single product) as max, most listings they have inflated pricing.

Speaking of personal preference, I still consider an active cable (branded one) with Terminus FE1.1 as a more safer bet.
Long run of USB 2.0 cable  (5m to 30m), this is not a popular application, and you can hardly resale such a cable in case that you do not actually need it any more.
Therefore, I do prefer getting married with a good quality of accessory, even when I do not use it that often.

7 Euros (with VAT) the cheapest 5m, for Greece at e-shop.gr

The missing information of all Low priced products, 5M length, this is power delivery potentials.

One brave Greek seller he did add an sincere description.
Provides up to 250mA of power to the connected device.

One brave Chinese OEM factory this it did add an sincere description.
Wire  UL 28 AWG*1Pair+24 AWG *2C+AL-foil+Braid

While if you are up to getting an true 500mA output, the cable it must be constructed with 20 AWG wires.

In the Greek market, an cable listed as CAB-U039 this collects the worst reviews, it stops working after a month.
Not true copper wires ...

After close examination, of U1173B Isolated USB communication cable for U1272A, the USB cable this is also specified (printed over the cable)  two pairs of 28 AWG + 24 AWG.

This is 2M in length cable.
Agilent / Keysight this was using Copartner Technology Corporation, this is a major Taiwan-based manufacturer, cable assemply business.

I will accept this information, as a fact, that all such USB communication cables, they are of low power consumption.
This information increases the chances for unbranded Active Extension Repeater, these serving up to 15M of cable length.
