About E-Band's New Universal "Quick Swap" Copper/Fiber Interface

  • This E-Band innovation enables the use of one radio design for any combination of copper, fiber or mixed interfaces
  • Simplifies ordering and stocking of radios
  • Reduces distributor/operator/installer capital expenditures/inventory
  • Provides E-Band distributors/integrators with a competitive advantage
  • Speeds response to customer (reduced order time and no advance configuring)
  • Improves reliability (weather seal doesn't need to be broken to change interface)
  • Grows and transitions with the customer's network
  • Eliminates the cost of sending units back to factory to modify interface, and reduces down time
The problem faced by the industry and customers

In the past, wireless distributors and integrators were faced with having to order and stock different radios with various GBIC (Gigabit Interface Convertor) interfaces for copper, fiber or a mixed connection configuration. The SFP (Small Form-Factor Pluggable) GBIC has historically been built into the design of the radio (inside the factory-sealed housing). This design presents a challenge to distributors, installers and their customers. First, distributors/installers need to respond quickly to customer needs, and having to order the exact interface type delays this response. Second, if the distributor/installer wants to have radios on hand to speed customer response, keeping a multitude of radios in stock with varying connection types is not cost effective and ties up capital. Third, if a customer's network evolves, for example from copper to fiber, making this change in the radio traditionally requires sending the unit back to the manufacturer and incurring the cost of converting the GBIC, which also has the negative consequence of breaking the weather/warranty seal.

E-Band's solution (patent pending)

Engineers at E-Band listened to customer input and designed an innovative solution to the fiber/copper interface problem. On new E-Band radios, the SFP is now external to the unit's housing. This means that the ODU (outdoor unit) for copper, fiber or mixed interface configurations is exactly the same. Swapping between different interfaces simply involves removing a retaining screw from the connector, pulling out the connector insert, sliding out the old SFP from the cable insert, changing the cable running into the connector, and then reversing the process (i.e., slide in the new SFP, install insert, install screw).
