[ Huaqiang Security Network News ] The general cable sheath has fire performance markings. Let's take the IBDN cable code as an example to explain how to identify it. 
Nordx/CDT offers three series of enhanced horizontal cables. They are the IBDN-1200, IBDN-2400 and IBDN-4800LX series. The IBDN-1200 consists of special cables such as 1212, 1213 and 1224. The IBDN-2400 and IBDN-4800LX series are similar. The first two digits (such as "12" "24"') are related to the maximum recommended data transfer rate. When used in IBDN Gigabit cabling solutions, the cable can be divided into 1.2 and 2.4 Gbps.
The third digit is related to the cable design and is expressed as follows:
· 1 indicates UTP and uses some halogenated materials (such as PVC, LSPVC or FEP)
· 2 means UTP and use low-smoke non-toxic materials (eg LSOH)
The last digit represents the level of flame propagation and is expressed as follows:
·1 means CM, C
MX general purpose;
· 2 indicates CMR (inc.FT-4)* shaft;
·3 indicates CMP flame retardant;
· 4 indicates IEC332-1.
Nordx/CDT also offers three series of fiber optic cables. They are IBDN-FX300, IBDN-FX600 and IBDN-FX2000 fiber optic cables. The fire performance is marked as:
OFN - non-conductor fiber optic cable
FNR - a non-conductor vertical trunk
OFNP - a non-conductor fiber flame retardant
