Product SKU: DH-PFM920I-5eUN
Product Overview
The Dahua DH-PFM920I-5eUN is a 305m unshielded CAT5e network cable designed for structured data cabling and compatible Power over Ethernet installations. Its four twisted pairs use 99.97% oxygen-free copper conductors with a 0.45mm diameter, helping provide consistent electrical performance for properly designed CCTV and networking runs. The cable is specified to 100MHz with controlled impedance, attenuation, return loss and crosstalk performance. A white PVC outer sheath carries CPR Eca flame classification, while the integrated polyester rip cord assists with opening the jacket during termination. The carton supplies 305m of bulk cable for multiple fixed runs; it does not indicate that a single 305m Ethernet link is supported. Connectors, patch panels and termination hardware are not listed as included.
Key Capabilities
305m Bulk CAT5e Cable
A full 305m carton supports structured cabling across multiple network runs for cameras, recorders, access points, intercoms and compatible data devices.
99.97% Oxygen-Free Copper
High-purity copper conductors help provide consistent resistance and transmission performance for correctly designed Ethernet and PoE installations.
Power over Ethernet Support
Compatible PoE devices can receive power and network data through one cable, reducing the need for a separate local power lead at each supported endpoint.
100MHz CAT5e Performance
The cable is specified with CAT5e transmission characteristics including 100 ± 15Ω impedance, controlled attenuation, return loss and near-end crosstalk performance.
CPR Eca PVC Sheath
The customised white PVC outer sheath is certified to CPR Eca flame-retardant class and complies with the listed vertical flame-propagation test.
Installer-Friendly Construction
Four colour-coded twisted pairs and an integrated 500D polyester rip cord support identification, sheath opening and organised on-site termination.
Best For
- IP Camera Cabling: Supports compatible network cameras and PoE devices through correctly designed cable runs.
- NVR and PoE Switch Installations: Suits fixed links between equipment racks, patch panels, outlets and endpoint devices.
- Commercial Structured Cabling: The 305m carton provides practical bulk length for multiple office, retail, warehouse and security-system runs.
- Oxygen-Free Copper Projects: Provides a documented 99.97% copper conductor specification rather than an unspecified or CCA construction.
- Protected Indoor Pathways: Suitable where white PVC UTP cable and CPR Eca classification match the project and environmental requirements.
Why Choose the DH-PFM920I-5eUN
The DH-PFM920I-5eUN gives installers a clearly specified Dahua-branded CAT5e cable for IP surveillance and general network infrastructure. Its oxygen-free copper construction, documented resistance and transmission figures, PoE support and 305m bulk carton make it a more dependable project choice than cable with unclear conductor material or electrical performance. Colour-coded pairs, a polyester rip cord and a compact 4.7mm outer diameter support efficient routing and termination, while the Eca-rated PVC sheath addresses the stated flame-performance requirement. Supplied by Security Wholesalers, this cable is best used after confirming the required category, pathway, run length, PoE load and environmental rating for the complete installation.
Buyer Decision Tips
Run-Length Tip: Treat 305m as the total carton length for multiple runs. Design every channel within the applicable Ethernet, structured-cabling and PoE limits for the connected equipment.
PoE Tip: Higher-powered devices and warmer cable bundles can increase voltage drop and heat. Confirm the device wattage, PoE standard, cable pathway and network-switch power budget before installation.
Environment Tip: This model is not listed as UV-resistant, water-blocked or direct-burial cable. Select a purpose-rated cable or compliant protective pathway for exposed, wet or underground locations.

Choosing the Right Model
- Choose the DH-PFM920I-5eUN if: You need 305m of white UTP CAT5e cable with oxygen-free copper conductors and PoE support.
- Choose CAT6 if: The project specification, future bandwidth plan or selected equipment requires a higher cable category.
- Choose shielded cable if: The pathway has significant electromagnetic interference and the entire shielded system can be terminated and earthed correctly.
- Choose outdoor cable if: The run is exposed to sunlight, moisture, temperature cycling or underground conditions.
- Confirm termination components: RJ45 plugs, keystone jacks, patch panels and patch leads must suit CAT5e, conductor dimensions and the installation method.
FAQs
- Is the Dahua DH-PFM920I-5eUN made from pure copper or CCA?
The DH-PFM920I-5eUN uses oxygen-free copper conductors with a stated purity of 99.97%. It is not described by Dahua as copper-clad aluminium cable. Pure copper construction generally provides more predictable resistance and PoE performance than CCA alternatives, but correct termination, run length, ambient temperature and connected equipment still affect the completed network link. - Does this CAT5e cable support PoE security cameras?
Yes. Dahua lists Power over Ethernet support for the DH-PFM920I-5eUN, allowing compatible IP cameras and other PoE devices to receive network data and power through the same cable. Actual performance depends on the PoE standard, device power demand, cable-run design, connector quality, temperature and the power budget of the NVR or PoE switch. - Can the full 305m box be used as one Ethernet run?
No. The 305m measurement is the total bulk-cable length supplied in the carton, not a statement that one 305m Ethernet or PoE channel is supported. Each cable run must be designed within the applicable structured-cabling, device and PoE distance limits. Longer links may require fibre, network extenders, intermediate switching or another approved transmission design. - Is the PFM920I-5eUN suitable for outdoor or underground installation?
Dahua specifies a white PVC outer sheath with CPR Eca flame classification but does not list UV resistance, water blocking, direct-burial construction or an outdoor environmental rating. Do not assume it is suitable for exposed or underground installation. Use a cable specifically rated for the environment, or place the cable within a compliant protected pathway approved for the project. - What is the minimum bend radius during installation?
Dahua specifies an installation bending radius greater than eight times the cable’s outer diameter. With a nominal outer diameter of 4.7mm, installers should avoid tight corners, crushing, kinks and excessive pulling force. Maintaining the required bend radius helps protect pair geometry, conductor integrity and transmission performance throughout the completed network cable. - Does the cable include RJ45 connectors?
The DH-PFM920I-5eUN is supplied as 305m of bulk CAT5e cable in a carton. Pre-terminated RJ45 plugs, keystone jacks, patch panels and patch leads are not listed as inclusions. The cable must be terminated using compatible components and appropriate tools, with the pair order, untwist length, strain relief and testing handled correctly. - What temperatures can the Dahua CAT5e cable handle?
Dahua specifies an operating temperature range of –20 °C to +60 °C and an installation temperature range of 0 °C to +50 °C. Storage is specified from –10 °C to +40 °C at less than 60% relative humidity. Cable should be conditioned, handled and installed within these limits to reduce the risk of jacket damage or performance issues. - What should I check before ordering this network cable?
Confirm that CAT5e performance suits the network, that the project requires unshielded white PVC cable, and that the planned environment does not require outdoor, UV-resistant, low-smoke or direct-burial construction. Also confirm run lengths, PoE loads, termination hardware and local cabling requirements. Security Wholesalers can assist with matching the cable to compatible CCTV and networking equipment.
