Product overview
Dome Splice Protection for Outdoor Branch and Joint Nodes
The GL-L5-BR houses fusion splices, routes stored fiber and separates the splice area from cable-entry sealing at an OSP joint or branch point. Its butt-entry dome layout brings the feeder and branch cables through the same base, while removable trays organize either single-fiber or ribbon-fiber splice sleeves.
Network function
The enclosure protects cable joints and branching fibers between feeder, distribution and downstream cable sections. It is intended for splice management rather than adapterized subscriber access, so fiber capacity, cable-entry diameter and tray type should be defined independently from port count or connector interface.
Standard product boundary
The GL-L5-BR is an unloaded splice closure with heat-shrink cable sealing. No adapter panel, hardened connector interface, PLC splitter, TAP ratio or optical insertion-loss value is assigned to the closure itself.
IP68 and temperature terminology
IP68 identifies the stated enclosure protection grade; it should not be rewritten as unlimited underwater operation without the project's immersion depth, duration and test method. The −40°C to +65°C value applies to a 10-cycle temperature test, not to a separately defined installation, storage or continuous operating-temperature range.
Design details
Design and Performance Details
The details below separate capacity, sealing, housing construction, environmental checks and tray selection.
Single-Fiber and Ribbon Capacity
Six tray positions support up to 144 single fibers at 24 fibers per tray or up to 432 ribbon fibers at 72 fibers per tray. This separates fiber-count planning from cable-port count and lets the same dome platform be specified for conventional loose-fiber splicing or higher-density ribbon projects.
Five Heat-Shrink Cable Entries
The base provides one oval port and four round ports for Φ8–18 mm cables. Heat-shrink sealing creates cable-specific entry interfaces rather than a universal gland; procurement should map every feeder and branch cable outside diameter to a port and include the corresponding sealing consumables.
IP68 Closure Protection
The GL-L5-BR has an IP68 protection grade for outdoor splice protection. This gives project teams a defined ingress-rating field for aerial, pole, wall, pipeline and manhole nodes, while the RFQ should still state any required immersion, pressure, re-entry or site-acceptance test conditions.
PP+GF Housing and Metal Hardware
The enclosure is identified as a PP+GF thermoplastic closure with AISI 304 stainless-steel components and rubber sealing parts. Recording these materials in the approved BOM helps distinguish the closure body, fastening hardware and sealing elements during sample approval and incoming inspection.
Environmental and Electrical Checks
The acceptance data includes a −40°C to +65°C temperature cycle over 10 cycles with no air leakage, plus insulation resistance above 2 × 104 MΩ. These values are test references; project procedures should define setup, conditioning and report requirements before batch acceptance.
#7 and #8 Splice Tray Options
Two tray versions use different splice-sleeve holders. Selecting the #7 or #8 tray before production aligns the holder layout with the planned sleeve arrangement and avoids treating tray count alone as a complete internal-configuration specification.

Capacity and Tray Configurations

Network placement
Where the GL-L5-BR Fits in the Network
The GL-L5-BR is used where outdoor cables must be joined or branched while splice trays, cable entries and site mounting remain controlled as separate project fields.
Aerial FTTH Branch Nodes
Using a fixed-capacity closure without mapping feeder and branch cable diameters can leave unused trays but no compatible cable entry. The GL-L5-BR combines one oval and four round Φ8–18 mm heat-shrink ports with 24–144 single-fiber capacity, allowing feeder-to-distribution splices to be organized at an aerial strand or pole-mounted ODN node. It can receive loose-tube or armored OSP cables and route the fibers into #7 or #8 trays. Before procurement, confirm every cable OD, the oval-port function, required fiber count, tray version, mounting bracket and heat-shrink consumables.
Pipeline and Manhole Splice Protection
A handhole closure selected only by "IP68" may still be too large for the chamber or mismatched to the incoming duct cables. The GL-L5-BR uses a 460 × Φ225 mm dome body, heat-shrink entries and a locking hoop to protect splices at pipeline, manhole or underground joint locations. Its six tray positions support expansion from 24 to 144 single fibers, while ribbon projects can reach 432 fibers. Buyers should confirm chamber clearance, cable bend space, cable OD, immersion or pressure-test conditions, grounding for armored cable and whether the closure will require planned re-entry.
Wall, Pole and Pedestal Distribution Points
Placing an inline closure at a branch point can force cables to reverse direction and consume unnecessary mounting length. The butt-entry GL-L5-BR brings all cables through one base, which suits wall, pole or pedestal locations where the feeder and branch cables approach from the same direction. Install it at a building entry, campus OSP transition or rural distribution point and route loose-tube, ribbon or armored fibers into the selected tray holder. The RFQ should define bracket type, mounting orientation, cable support, fiber count, entry allocation, label map and clearance for opening the locking hoop.
Mixed Single-Fiber and Ribbon-Fiber Project Procurement
Calling a closure "144F" does not show whether the project uses 144 individual fibers or ribbon construction, and those formats require different tray capacity planning. The GL-L5-BR publishes 24 single fibers or 72 ribbon fibers per tray, with six tray positions and #7 or #8 holder options. It can be specified at backbone-to-distribution joints where cable types vary between network sections. Before sample approval, freeze the fiber format, splice method, sleeve dimensions, tray layout, cable construction, cable-entry map, capacity reserve and any required test or inspection record.

Company background
Glory Optical Production and Project Support
Glory Optical Communication is a Ningbo-based passive fiber optic infrastructure manufacturer founded in 2008, with a 20,000 m² manufacturing facility, more than 300 passive optical products, supply to over 50 countries and OEM/ODM project support.
Enclosure Molding and Structural Review
Glory's mold and CNC capability supports control of enclosure geometry, gasket position, cable-entry details and mounting interfaces. For the GL-L5-BR, project review should focus on the dome, base, locking hoop, entry layout and tray-support structure.
Closure and Tray Assembly
The assembly workflow covers fiber boxes, splice closures, trays and cable-management parts according to a confirmed drawing and BOM. This lets the supplied tray quantity, holder type, sealing kit and mounting accessories be checked as one configuration.
Specification and Sample Workflow
Project support can include drawing or photo confirmation, specification review, sample planning, testing, labeling, packaging and batch supply. The exact inspection items should be agreed for the GL-L5-BR order rather than assumed from a general closure category.
Project Documentation
Buyers can request the applicable datasheet, approved drawing, inspection record, packing information, labels and compliance documents. The final document set depends on the confirmed closure configuration and acceptance plan.
Project checklist
Confirm the Cable Map and Tray Plan Before Ordering
Send the fiber format, total splice count, cable construction and diameter, oval and round port allocation, #7 or #8 tray preference, installation location, mounting hardware, heat-shrink kit, labels, inspection requirements and packaging instructions.
