Fiber Distribution Box Outdoor

GL-A1-16R Fiber Optic Terminal Closure

The GL-A1-16R is a 16-port fiber optic terminal closure for feeder-to-drop termination and distribution in FTTx networks. Its 290 × 210 × 82 mm PC/ABS housing is listed for IP66 protection, with SC/APC or SC/UPC connector configurations and an operating range of −40°C to +85°C. Wall and pole arrangements support building-entry, MDU and campus access points; confirm the adapter population, internal fiber layout and cable-entry sealing parts for the selected assembly.

Technical Specifications

Optical acceptance: Confirm the interface, test wavelength and measurement reference for the stated insertion-loss and return-loss figures. These figures do not define the total loss of an unspecified internal splitter or a complete subscriber link.

Wall and Pole Configuration

The 16-core entries describe the listed configuration capacity; the 16-port specification describes connector positions. Confirm the actual adapters, splices, pigtails and any splitter separately. Rack mounting is mentioned in the installation description and requires its model-specific bracket and clearance confirmation.

GL-A1-16R Structure and Cable Management

Feeder-to-Drop Fiber Organization

The enclosure provides a managed transition from feeder cable to the selected drop-cable connections. Define the incoming fiber allocation, splice arrangement and numbered adapter schedule before assembly. Use the 16-position connector requirement together with the approved internal map.

PC/ABS Housing with IP66 Protection

The material is described as high-impact PC+ABS with UV stabilization, and the listed wall and pole configurations use PC/ABS. Confirm the cable seals, closure arrangement and required assembled IP66 test conditions for the actual installation.

SC/APC or SC/UPC Configurations

Specify the required SC polish and matched pigtail and patch-cord assemblies throughout each connection. The published optical entries distinguish APC and UPC return loss. Keep connector preparation and test conditions with the selected interface specification.

Internal Routing and Cable Retention

Organize feeder retention, fiber slack and splice protection around the supplied tray and adapter arrangement. Confirm the minimum bend limits of the actual fibers and cables and the mechanical retention parts fitted to the order. No numerical bend-radius or cable-retention load is specified.

Wall and Pole Mounting Options

Both listed installation configurations use a 290 × 210 × 82 mm housing and black color. Select the bracket, fixing parts and cable approach for the site. Check opening access, plug clearance and cable support before approving the mounting drawing.

FTTH and FTTx Application Planning

MDU and Building-Entry Fiber Distribution

At a multi-dwelling building, the feeder cable and subscriber drops need an organized termination point with a clear connection schedule. Install the selected GL-A1-16R wall or pole arrangement at the approved building-entry or access location. The 16 SC connector positions support the specified pigtail and drop configuration, while the internal layout must follow the building fiber plan. Before ordering, confirm cable construction, entry sealing, splice allocation, adapter polish, labels and any required splitter. Check the assembled protection conditions and the space needed to open and service the enclosure.

Campus and Business-Park Access Nodes

A campus or business park may distribute feeder fibers to several buildings, creating different requirements for route allocation and drop lengths. Use the GL-A1-16R as the planned termination node between the distribution cable and matched drop connections. Select the internal circuit for the project topology and confirm where any PON splitting or WDM components are located. Before procurement, approve the wall or pole mounting kit, cable sizes, connector schedule and fiber routing. Include the intended service-access procedure and optical inspection requirements with the assembly drawing and site installation plan.

Outdoor Cabinets and Distributed Fiber Links

An outdoor cabinet or distributed communications site needs the enclosure and cable arrangement matched to its installed position. The GL-A1-16R provides the listed PC/ABS housing and wall or pole configuration for the planned fiber termination point. Confirm the mechanical space, cable approach and SC/APC or SC/UPC connections before selecting the assembly. For a proposed mobile, DAS or equipment-side link, have the system design define fiber allocation, receiving interfaces and optical-path requirements. Request project-specific evidence for the relevant conditions rather than treating an application illustration as a product qualification.

Network and Installation Context Illustrations

These illustrations provide planning context for passive fiber termination. Confirm the actual network components, interfaces and enclosure location for the project; the illustrations do not define the internal optical circuit of this model.

Installation, Inspection and Project Documentation

The supplied description names Telcordia GR-487 and IEC 61753 without identifying a test report, edition or performance category. Confirm the applicable project criteria and supporting documents for the ordered assembly. Any ITU-T requirement should be identified by its specific recommendation and scope.

Define the required optical acceptance and service-access procedure in the project documents. If monitoring or in-service testing is required, identify the optical access arrangement and method in the approved circuit.

Selection and Ordering Details

Send Glory Optical the required port schedule, feeder/drop cable details, connector polish and installation drawing for configuration review. Include any special mounting, component loading, labeling and inspection requirements with the quotation request.
