The short answer

What this product is specified for.

Included in the quotation

  • Port count, connector polish and power configuration
  • Model-level datasheet and test data
  • Optical budget and splitter plan for the ODN

An outdoor camera or AP is protected by a system, not a single device. The surge can enter on the copper Ethernet cable, the power pair or the mounting structure. A Type 2 SPD at the cabinet entry diverts the transient before it reaches the switch or the ONU; a second device at the pole may be needed on a high-exposure site. The SPD must be bonded to the local earth with a short, low-inductance conductor.

The range covers Ethernet/PoE SPDs for Cat5e/Cat6 runs, 48 V DC power SPDs for PoE/PoF cabinets, grounding kits for poles and cabinets, cable glands for IP-rated enclosures, and weatherproof enclosures for the ONU/switch. The SPD is a wear item: after a large surge it may be degraded or failed, so choose a model with a status indicator and keep a spare.

Do not rely on the word “fibre” to remove every surge path. The fibre is dielectric, but a PoF hybrid cable still has a 48 V copper pair, and the camera/ONU has a housing and a local earth. Protect the power pair at the entry, bond the housing, and keep the copper section short. The best surge protection is often a shorter copper path.

Configuration table

The numbers that decide the fit.

Values are from the model datasheet. Where a value is model-dependent, the table says so instead of guessing.

Surge ratings and IP ratings are model-specific. The SPD, enclosure and bonding are selected together for the site.

Engineering features

What changes on site.

Type 2 protection

Clamps the transient at the cabinet entry before it reaches the switch or ONU.

PoE and 48 V DC

Separate SPDs for the Ethernet/PoE pairs and the 48 V DC power bus.

Bonding kit

A short, low-inductance earth conductor is part of the protection; a long wire defeats the SPD.

IP-rated entry

Cable glands and enclosures keep water out of the cabinet and strain-relieve the cable.

Status check

Choose an SPD with a status window or remote contact; a failed SPD can look like a working one.

Spare on site

Keep a spare SPD and a spare gland; a replaceable device is faster than a site redesign.

Selection guide

Which configuration fits which site.

Start from the site, not from the model. The table is a starting point; the final check is the optical and power budget.

An SPD without bonding is not protection. Use a short earth conductor and a local earth electrode.

Product FAQ

Surge Protection & Installation Accessories: questions before the order.

If your question is not here, send the site details and we will answer with the calculation, not a brochure.

Ask an engineer

Do I need an SPD on a PoE camera under 100 m?

Yes if the cable leaves the building or runs to a pole. The 100 m limit is about data, not surge exposure. Use a Type 2 SPD at the building entry and bond the camera housing.

Does fibre remove the need for surge protection?

No. The fibre is dielectric, but a PoF hybrid cable has a 48 V copper pair and the endpoint has a housing and earth. Protect the power pair and bond the housing.

Where should the SPD be installed?

At the cabinet or building entry, where the surge current can be diverted before it enters the equipment. A second device at the pole may be needed on high-exposure sites.

How do I know an SPD has failed?

Look for a status window or a remote contact. A thermal disconnect often opens the device after a large surge; the equipment keeps working until the next event.

What IP rating do I need?

The enclosure rating for the site, not the SPD alone. Use IP66/IP68 glands and an IP-rated box for an outdoor cabinet; the SPD itself is inside the box.

Can I use a standard Ethernet SPD for PoE?

Only a PoE-rated SPD. A standard data SPD may not carry the PoE current; confirm the PoE class and the current rating.

No obligation. The plan states its assumptions so your engineer can check it.
