Total Access 300 GigE SFU ONT with RF Overlay and SWRD Powering Installation and Maintenance Guide
Components and Interfaces
The ONT consists of the following components and interfaces:
• Mechanical Components
• Electronics Module
• Circuit Board
• SWRD power supply
Mechanical Components
The ONT is designed for outdoor applications. The Corning Systems Model FNI‐NG series
outdoor NID housing is intended as a demarcation point between the Telco and subscriber
wiring and house fiber‐to‐the‐home (FTTH) electronics.
Outer Enclosure
The Outer Enclosure provides both environmental control (weatherproofing) and access
control.
Outer Enclosure Security Locking Feature
The enclosure is intended for use on the outside of a building and is designed to meet US
environmental requirements. The unit is weather hardened and is able to withstand 70 m.p.h.
wind driven rain, high temperature, cold temperature, drop tests and all other GR‐49,
GR‐950, and GR‐487 requirements.
The dimensions are approximately 286 mm (11.25ʺ) x 330 mm (13ʺ) x 110 mm (4.3ʺ).
The external door provides access to the RJ‐11 test connectors, POTS Two‐screw Terminal
Bridges, and Ethernet RJ‐45 connectors. The enclosure door is held in the closed position by
two "snap" door retainers (see Figure 2 on page 9). To open the door these two snaps must be
disengaged at the same time.
The Outer Enclosure Door has a double security locking feature provided by the third molded
part (see Figure 2 on page 9). This provides the following capabilities:
• Subscriber access with the flat head screw
• Telco personnel access via the Pin‐in Hex‐head screw
• Secure door (padlock)
