Product Overview

The Indoor 8 Port Optical Distribution Box from Spring Optical is a compact, wall-mounted enclosure engineered for reliable fiber termination and distribution in indoor FTTH and FTTx environments. In Spanish-speaking markets (particularly in Spain and Latin America, where FTTH deployments are widespread), this product is commonly referred to as Caja de distribución óptica (often abbreviated as CDO or similar in technical documentation and supplier catalogs). Designed specifically for building entrances, floor distribution points, multi-dwelling units (MDUs), offices, and controlled indoor spaces, this fiber optic wall-mounted box provides organized management of pre-connectorized drop cables (typically SC/APC) while maintaining proper bend radius and protecting connections from dust and mechanical stress.

Key installation features include a dedicated porta ganancia (slack storage bracket) for incoming fiber reserve loops, color-coded ports (red for inlet/feeder, blue for outlet/user drops), and a removable transparent cover that increases internal usable space by approximately 40% when space is limited. Side protectors seal openings after cover removal, ensuring tidy cable routing and basic dust protection suitable for indoor applications.

Qualified installation teams benefit from straightforward mounting using standard tools, level positioning of the slack bracket first, followed by secure fixing to wood, metal, or masonry surfaces with appropriate anchors (such as tarugos for concrete walls). The design supports rapid deployment in last-mile FTTH networks, offering low insertion loss, high return loss performance, and simplified maintenance access.

Applications of the Indoor 8 Port Optical Distribution Box

The Indoor 8 Port Optical Distribution Box is ideally suited for indoor FTTH deployment points such as apartment building risers, floor distribution closets, commercial building entrances, hotels, and campus networks. In regions like Spain and Latin America, where the product is frequently specified as Caja de distribución óptica, it serves as an efficient transition and termination enclosure between feeder cables and subscriber drop cables, providing secure fiber management in space-constrained indoor locations.

Typical Network Architecture with the Indoor 8 Port Optical Distribution Box

In PON-based ODN deployments, the Indoor 8 Port Optical Distribution Box is commonly installed at secondary distribution points inside buildings. The feeder cable enters through the red inlet port, with excess length carefully coiled on the rear slack storage bracket to ensure minimum bend radius compliance (≥30 mm dynamic/≥15 mm static). Internal patching or fusion splicing (if required) routes the signal to the output adapters. Subscriber drop cables connect directly to the blue ports without internal slack storage, exiting through sealed ports to minimize clutter and maintain clean routing.

Product Advantages

The Indoor 8 Port Optical Distribution Box offers good scalability for subscriber growth, supporting 8 connections with potential for splitter-based expansion. Its compact, high-density layout maximizes usable space in indoor risers and closets. Installation is efficient and repeatable thanks to the pre-configured slack bracket, color-coded ports, and standard tool compatibility, reducing deployment time for field teams. Long-term reliability is ensured by durable materials, wide temperature tolerance, and secure cable management that protects fibers from stress and contamination.

FAQ

Q1: What is the ingress protection rating of this Indoor 8 Port Optical Distribution Box?

A: IP54 for basic indoor dust and splash resistance; higher IP-rated variants are available for semi-exposed locations.

Q2: Does the box support optical splitters?

A: Yes, it can accommodate a 1×8 PLC splitter for passive distribution in FTTH networks.

Q3: Which connector type is standard?

A: SC/APC is standard for low back-reflection in PON systems; UPC versions are available on request.

Q4: How is fiber slack managed?

A: Incoming feeder slack is stored on the rear porta ganancia bracket; outgoing drop cables connect directly without internal coiling.

Q5: What safety measures are required during installation?

A: Use eye protection when handling live fibers, ensure qualified personnel perform work, and follow local safety regulations.

Q6: Is the enclosure suitable for outdoor use?

A: No, this model is optimized for indoor environments; outdoor applications require IP65/IP67-rated variants.

Manufacturer Introduction

Spring Optical specializes in passive fiber optic connectivity solutions for FTTH and enterprise networks. With production facilities focused on enclosures, connectors, cables, and assemblies, the company delivers consistent quality and supports global telecom operators, ISPs, and distributors through ODM/OEM services. All products undergo rigorous testing to meet international standards.

Packing and Transportation

Each unit is individually packed in a protective inner box with foam inserts to prevent damage during handling. Contents include the distribution box, porta ganancia slack bracket, mini fixing screws, wall anchors (where applicable), and installation instructions.

Outer cartons are made of sturdy corrugated material with moisture-resistant liners. Labels include model number, quantity, "Fragile – Optical Equipment" warnings, and batch traceability information.

Storage Recommendations: Keep in a dry, ventilated warehouse between -10°C and +40°C. Avoid direct sunlight, chemicals, and excessive vibration. Do not exceed recommended stacking height to prevent deformation.

Transportation: Use covered vehicles to protect from rain and dust. Handle carefully to avoid impacts. International shipments comply with IATA/IMO regulations for non-hazardous telecom equipment. Palletize for secure container loading.

For detailed datasheets, compatibility verification, or project-specific configuration advice, please contact the Spring Optical technical team with your network requirements. We are ready to discuss deployment details with telecom engineers and planners.

Step-by-Step Installation Guide

Step 1 Measure and mark the mounting position on the wall using a measuring tape, level, and marker. Determine the appropriate height (typically 1.5–2.5 m for accessibility and safety). Mark the fixing holes for the gain holder accessory, ensuring the position allows for level installation.

Step 2 Place the gain holder accessory (porta ganancia / slack storage bracket) on the wall, ensuring that it is perfectly level. Then install the fixing screws into the wall, securing the accessory using only screws if the surface is wood or metal, or use wall plugs/anchors (tarugos) for masonry/concrete walls. Use a 6 mm or 4 mm carbide/tungsten (widia) drill bit depending on the type of hole required. Mount the CDO (Optical Distribution Box) onto the gain accessory and secure it with the mini fixing screws provided for this purpose. To install the lower screw, lift the protective cover.

Step 3 Once the installation is complete, begin installing the pre-connectorized cable. Place the excess fiber (gain / slack) into the rear accessory. After completing this step, proceed with the installation: lift the cover and connect the incoming fiber cable (or feeder cable) to the RED port. The outgoing cable does not store any slack inside the CDO; it should be connected directly to the BLUE connector. After connecting, close the cover.

Step 4 If necessary due to lack of space, remove the transparent cover. This will provide approximately 40% more usable space inside the box. Then install the side protectors to seal the openings in the enclosure.
