The Allied Telesis G8 Series offers the latest industry standards in flexible, full-duplex Gigabit Ethernet connectivity. These hot-swappable, fiber and copper interfaces simply plug into a Gigabit Interface Converter (GBIC) slot on Allied Telesis GBIC-compatible products. Configurations can be optimized to meet varied distance and service requirements.

The 4 Channel Telephone to Fiber Converter is a high performance fully digital fiber optic interface for links between a PABX and any touch tone telephone. It is designed for applications such as PABX/Line extension between buildings or to a remote location (e.g. from a central control room to a security guard post) where only one or a few telephones are required. A typical application example could be the emergency telephone systems of highways or other ITS (Intelligent Transportation System) applications. The Telephone to Fiber Converter can also be used to connect any two touchtone telephones to form a dedicated intercom system. The Telephone to Fiber Converter is available with common optical fibers operating at wavelengths of 850nm, 1300nm or 1550nm. Both multimode and single mode versions are available to suit different application requirements. The longest transmission distance supported by the Telephone to Fiber Converter is 2 km on multimode fiber or 20 km over single mode fiber. For longer distances or special transmission requirements, please consult OSD.
