Manufacturer-specific cable series.
For Draka, UC means network cable, 1500 means the cable is rated up to 1500 MHz.
High Screen is the type of shielding used (another grade would be Super Screen).
22 stands for AWG22, which describes the diameter (0.65mm) of the copper wires in the cable.
Cable categories according to ISO 11801 specify minimum requirements for cables.
This is a Category 7a (or Cat 7a for short) cable.
S/FTP describes the shielding makeup of the cable.
The S before the slash means there is an overall copper braid shield, and the FTP means each twisted pair has an individual metal-foil shield.
4P stands for four (twisted) pairs. Cables for use with Ethernet networks generally contain four pairs.
The "3P verified" marking means that this cable has been independently tested by 3ptest to comply with EU Construction Products Regulation, which covers environmental and fire safety.
IEC 61156-5 describes standards for Category 7/7a cables in more detail.
LSHF stands for "low-smoke, halogen-free", which is required for fire safety.
These markings describe the fire properties of the cable according to EU CPR in detail.
Dca is one of the lower-performance classes (best performing is Aca, worst is Fca).
s2 defines smoke production (amount and kind of smoke).
d1 defines production of flaming droplets. d0 would mean that no flaming droplets are produced.
a1 defines whether the gas produced during a fire is acidic or conductive
For each of these qualifiers (s/d/a), a smaller number is better.
Partially cut-off running meter in the lot number.
