Product overview
A Compact FTTH Termination and Subscriber Handoff Point
The GL-FTB-4F combines cable entry, fiber splicing, slack storage and adapter presentation in one enclosure. It is intended for low-count access nodes where an outside cable must be transitioned to customer-side cabling without using a larger distribution box.
Core Enclosure Configuration
The GL-FTB-4F provides two SC or LC adapter positions, capacity for splicing and storing up to four fibers, an internal fusion-splice tray, cable entry for Ø3–13.5 mm cable and wall- or pole-mount installation. Its IP65 housing supports indoor and outdoor FTTH termination points.
What Must Be Defined per Order
Adapter format, UPC or APC polish, splitter loading, pigtail length, cable construction, exact gland allocation, mounting accessories, lock arrangement, labels and packaging must be confirmed in the approved BOM. Optional fields are not treated as standard loaded content.
Open enclosure with hinged splice tray, gasketed cover and cable-management area.
Internal routing view before adapters, pigtails or an optional micro PLC splitter are loaded.
Mounting-hole center spacing: 110 mm horizontally and 175.5 mm vertically.
Capacity is not the same as port count
The box has two adapter positions but can splice and store up to four fibers. LC duplex adapters can present more connector channels than two SC simplex adapters, so the connector count, active-fiber count and internal splice schedule must be stated separately in the project drawing.

Technical Advantages of the GL-FTB-4F 2 Port Fiber Termination Box
Each point below connects a technical feature to a practical selection or installation decision.
Two Presented Ports, Four-Fiber Management
Two adapter positions accept SC simplex or LC duplex formats, while the tray accommodates splicing and storage for up to four fibers. Separating presented ports from internal fiber capacity prevents an underspecified splice plan and lets buyers match the enclosure to a one- or two-subscriber handoff.
IP65 Indoor/Outdoor Housing
The UV-resistant engineering-plastic enclosure has an IP65 rating and a −40°C to +85°C operating range. Compared with an indoor wall outlet, the sealed housing provides a defined dust and water-jet barrier for exterior walls or poles; IP65 does not indicate continuous submersion.
Ø3–13.5 mm Cable Entry Range
The Ø3–13.5 mm cable-entry range covers outdoor cable or indoor drop cable. This gives project teams one compact housing for several feeder or drop constructions, provided each actual cable outside diameter, gland allocation and sealing part is checked before the BOM is released.
Controlled Internal Fiber Routing
A hinged fusion-splice tray separates splice protection and fiber storage from the lower cable-entry area. The page specifies an internal bend radius greater than 30 mm, helping installers route pigtails and stored fiber without forcing tight turns; the final route should follow the approved fiber map.
SC/LC and UPC/APC Interface Choices
The adapter field supports SC simplex or LC duplex, with UPC as the default polish and APC available. Insertion loss including the adapter is specified at ≤0.2 dB, with return loss of ≥50 dB for UPC or ≥60 dB for APC; scope and test method should be confirmed for the ordered assembly.
Optional Splitter and Pre-Termination
The enclosure can be ordered with a 1×2 or 1×4 micro PLC splitter, pre-installed connectors and specified pigtails. Factory loading converts separate field components into a controlled assembly, but the splitter ratio, connector polish, pigtail length, port map and optical report remain order-specific rather than standard.
Product family and options
GL-FTB-4F Configuration Paths
The GL-FTB-4F is one enclosure model with several loading options. These options should be selected as mutually compatible BOM fields, not treated as one universal default configuration.
Splice-and-Patch Terminal
Use the housing with two selected SC simplex or LC duplex adapters and the required pigtails. State UPC or APC polish, active-fiber count, pigtail length and the splice-to-port schedule.
Micro PLC Splitter Terminal
Add one 1×2 or 1×4 micro PLC splitter when the node must divide a PON feed. Confirm the actual splitter package, input/output termination, connectorization, wavelength requirements and worst-port loss in the approved splitter datasheet.
OEM Loaded Assembly
Specify pre-installed connectors, pigtails, optional splitter, housing identification and packaging artwork. A controlled sample or drawing should define exactly which components are factory fitted and which work remains for field installation.

Model and Capacity Table
| Model | Fiber Capacity | Adapter Positions | Adapter Format | Splitter Space | Dimensions |
|---|---|---|---|---|---|
| GL-FTB-4F (NID) | Up to 4 fibers for splicing and storage | 2 | SC simplex or LC duplex | Optional 1×2 or 1×4 micro PLC | 208 × 153 × 52 mm |
Optical Interface Specifications
| Parameter | Specification | Boundary to Confirm |
|---|---|---|
| Connector interface | SC simplex or LC duplex adapters | Adapter and mating connector must use the ordered format. |
| Polish type | UPC default; APC optional | Keep polish consistent across adapter, pigtail and connecting cord. |
| Insertion loss | ≤0.2 dB, including adapter | Confirm whether the limit applies per mated pair or to the complete loaded path, then state the test reference in the order. |

Optical values require a defined test boundary
The enclosure itself is passive mechanical hardware. Insertion-loss and return-loss limits relate to the fitted connectorized path, so the purchase specification should define whether the ≤0.2 dB limit applies to one mated adapter pair or the complete pre-terminated assembly. Add the agreed reference plane, wavelength and report format to the order.
Splitter Configuration Table

2 Port Fiber Termination Box Applications for FTTH and Access Networks
Use the GL-FTB-4F where the required port count, splice schedule, cable entry and environmental rating fit this specific enclosure.
Outdoor FTTH Subscriber Handoff
An indoor wall outlet does not provide a defined exterior dust and water-jet barrier, while a large distribution box adds unused capacity at a single-home handoff. The GL-FTB-4F uses an IP65 housing, two adapter positions and four-fiber splice/storage capacity at an exterior wall or pole between the provider cable and subscriber drop. It accepts Ø3–13.5 mm cable and SC simplex or LC duplex interfaces. Before purchase, confirm cable OD, UPC/APC polish, active-fiber count, mounting hardware, gland allocation and whether adapters and pigtails arrive factory fitted.
Small Office or Commercial Access Point
Leaving splices and patch connections in separate unprotected fixtures complicates labeling and fault isolation at a small business demarcation point. This compact NID places the splice tray, stored fiber and two presented adapter positions inside one lockable enclosure, installed on an internal or external wall or on a pole near the service entrance. SC simplex supports a conventional presented interface, while LC duplex can increase connector density within the listed positions. Procurement should define the circuit count, connector/polish, pigtail schedule, cable OD, port labels and optical acceptance boundary.
MDU Floor or Unit-Level Fiber Termination
Using a two-port terminal as the main distribution point for a high-density MDU would constrain expansion and confuse port capacity with subscriber count. The GL-FTB-4F is better positioned at a floor, riser branch or individual unit handoff where no more than two adapter positions and four managed fibers are required. The box can transition an approved Ø3–13.5 mm riser or drop cable to SC or LC connections. Buyers should verify fire-rating requirements for the building route, mounting location, fiber map, lock access and whether a higher-capacity distribution box is needed upstream.
GPON or XGS-PON Split-and-Terminate Node
A bare splitter left beside separate adapters creates an undefined fiber route and makes the delivered BOM difficult to repeat. The GL-FTB-4F can house an optional 1×2 or 1×4 micro PLC splitter with connector and pigtail loading, forming a compact split-and-terminate point at a wall- or pole-mounted access node. It can connect the incoming PON fiber to the required SC or LC outputs, but the enclosure does not determine optical budget. Confirm splitter package, ratio, wavelength, actual worst-port loss, connector polish, output map and test report before approval.
