Product Description

G.703 Surge Protected Balun Converter — 75 Ohm BNC to 120 Ohm RJ45 for Outdoor E1 Cabinets

Lightning-induced transients on outdoor coax runs are the usual cause of E1 card failure, so this version inserts a gas discharge tube network ahead of the matching transformer. The converter still performs the plain 75 to 120 Ohm conversion with two BNC connectors and one RJ45 port, but clamps a 5kA 8/20 microsecond surge before it reaches the equipment, and holds 1kV DC isolation between the coax and the twisted pair.

Protection Ahead of the Transformer

Gas discharge tube per coax port handles 5kA 8/20 microsecond surges and recovers automatically after the event.
Clamping network limits let-through voltage below 30V so the receiving E1 card sees a safe pulse.
Protection sits between the BNC and the matching transformer to keep the transformer out of the fault path.

Built for Outdoor Enclosures

Die-cast aluminium housing with sealing gasket fits tower base cabinets and roadside E1 radio sites.
Operating range of -40 °C to +85 °C covers rooftop and desert deployments.
Grounding stud with M4 thread bonds the enclosure to the cabinet earth bar.

Electrical Behaviour

Insertion loss below 1.2dB including the protection network — still within G.703 budget for 300m runs.
Return loss above 16dB and 1kV DC reinforced isolation between coax and twisted pair.
Replacement GDT modules available separately for field maintenance.

Search Terms and Alternative Names

Buyers and engineers describe this item in several ways. The same unit is ordered as G.703 BNC to RJ45 Balun, E1 BNC to RJ45 Converter, 75 Ohm BNC to 120 Ohm RJ45 Converter or E1 Coax to RJ45 Balun. All of these names refer to the passive G.703 75 Ohm to 120 Ohm converter described above: coax on one side, balanced twisted pair on the other, no power supply and no configuration. If your tender documents or BOM use any of these terms, quote this model directly and we will ship the matching version.
