As the migration from copper to fiber continues, fiber connections are being deployed closer to users' homes. Consequently, OLTs in FTTx networks are now positioned nearer to the end users. The small-capacity OLTs and accompanying outdoor cabinets are becoming increasingly preferred due to their compact size, lightweight, cost-effectiveness, and ease of deployment. In fact, small-capacity OLTs represent about 80% of total OLT deployments, while small-capacity outdoor sites account for roughly 80% of all outdoor site installations.

Wide-Ranging Applications of Outdoor Sites

To bridge the digital gap between urban and rural regions and to ensure widespread access, various countries have initiated rural broadband projects. Examples include Thailand's Village Broadband Internet Project and Egypt's Decent Life Initiative. Many nations even offer free Wi-Fi in remote areas. Operators are increasingly focused on expanding coverage in suburban, rural, and isolated locations, where populations are sparse and demand for numerous installations exists. Small outdoor OLTs provide the necessary flexibility to ensure access in these remote regions.
In urban settings, which face high user densities and substantial populations, competition remains fierce. The broadband penetration in urban centers is nearing saturation, making new commercial properties and communities the new battleground. New market entrants aim for rapid network deployment, while established operators seek to utilize existing site resources, such as those from mobile base stations or fixed network access points, to facilitate quicker and more economical installations. Regardless of the scenario, small outdoor sites offer significant advantages.

Deployment Challenges and Requirements for Outdoor Sites

Outdoor locations face numerous challenges due to harsh environmental conditions. For instance, setups must endure extreme temperatures, high solar radiation, and severe dust storms, particularly in tropical desert climates. Similarly, locations in tropical oceanic regions must withstand high temperatures, humidity, corrosive salt mist, frequent thunderstorms, and strong typhoons.
Limited real estate for deployment and extended timelines due to land acquisition add engineering risks that operators must navigate. The need for specialized engineering tasks—like trench digging and fiber splicing—makes outdoor deployment even more costly and complex. In rural areas, where a multitude of sites demand remarkably cost-sensitive solutions, installation and maintenance difficulties are exacerbated by challenging transportation logistics. Additionally, some areas may experience unstable electrical grids and recurrent power outages, necessitating stable power supply systems and adequate battery backups for the main equipment.
Urban deployments require rapid site installations with scalable capacity while effectively utilizing existing resources to minimize investment. This includes preserving VoIP services while supporting diverse offerings, alongside reusing legacy optical cables, power cabinets, or even cable distribution resources during upgrades.

Consequently, the ideal small outdoor cabinet must effectively address these common challenges while also catering to the unique needs of urban and rural contexts.

Light Cabinet Solution

Leveraging years of experience in the access network sector, ZTE has developed the Light Cabinet solution to enable economically efficient deployment of small-capacity outdoor sites. This solution features four key benefits: lightness, reliability, reusability, and sustainability.
Light
The benefits of rapid deployment via lightweight cabinets minimize initial investment costs. ZTE's small OLT cabinets, constructed from aluminum enclosures, exhibit exceptional anti-corrosion properties and are at least 30% lighter than galvanized iron cabinets of equivalent size. They support versatile installation methods, including pole or wall mounting. Despite their reduced weight, these cabinets encompass a wide range of functionalities, such as structural support, power management, monitoring, cable distribution, and temperature regulation, simplifying deployment processes. ZTE's EC100 cabinet is notably light, can be pre-connectorized to eliminate reliance on specialized technicians, thus reducing installation time and associated labor, logistics, and engineering expenses.
The "light" characteristic extends to operational efficiency, with low energy consumption and minimal noise. Pursuing green design principles, ZTE's small OLT cabinets incorporate in-house developed high-efficiency folded-plate heat exchangers along with intelligent fan speed regulation strategies to optimize energy efficiency and thermal management. If accommodating up to 16 PON ports, natural cooling is utilized, meeting ETS 300 753 Class 4.1E protected-area standards.
Reliable
In response to the demanding outdoor environment, ZTE's outdoor cabinets uniformly meet extreme climatic requirements including severe temperature fluctuations and high humidity. The heat dissipation mechanism ensures operational integrity at 50 degrees Celsius under direct sunlight. With a closed architecture separating internal and external airflow, corrosive elements are effectively blocked from entering the cabinet. Customized double-layer aluminum enclosures and hot-dip galvanized assemblies enhance the cabinets' corrosion resistance. The IPX5 rating permits them to defy typhoon and thunderstorm conditions often seen in tropical regions. Additionally, moisture prevention is enforced with anti-condensation technical solutions, including sponges and sealing strips. Moreover, the cabinets exhibit surge current tolerances up to 50 kA, accommodating even the strongest storms and hurricanes as classified by industry standards. Built-in IK10 anti-vandal structures enhance durability further.
Reliable power supply is critical for outdoor setups. ZTE's small-capacity outdoor PON OLT cabinets utilize high-performance power units that offer wide voltage input ranges, automatic recovery from faults, and remote monitoring features, safeguarding the battery against irregularities. These cabinets support both lead-acid and lithium-ion battery configurations, allowing variability in battery capacity.

Reusable
Operators leveraging existing outdoor sites can deploy FTTx networks using current resources to save costs. ZTE’s small-capacity outdoor PON OLT cabinets can draw from the power supplies of already established sites. Installation can be completed on-site without relocation. Specifically, the lightweight EC100 cabinet accommodates a broad pole diameter spectrum from 60-380 mm, enabling co-installation on the same poles or towers with existing mobile BBUs or cabinets on utility poles.
Reusable application also applies; ZTE OLT cabinets within existing networks can be upgraded to support XGS-PON services with just enhancements in thermal management systems and adaptable power supply configurations, while old lead-acid batteries can transition to lithium-ion with modifications to the battery compartments.

Sustainable
During various access network projects, small outdoor cabinets designed for sustainability have been positively received by operators due to their scalability and equipment compatibility.
For instance, the EC70E cabinet allows support for up to 64 GPON ports or 32 XGS-PON ports with a flexible battery capacity configuration. All ZTE small cabinets exhibit scalable designs, adhering to a redundancy level of 50%-85% for optical distribution fiber and 1+1 power rectifier backup. The high-power XGS-PON cards ensure effective heat management, offering a backup power solution for 2-5.2 hours under full operational loads.
Additionally, ZTE supplies specialized small cabinets that can integrate optical splitters, video multiplexers, and OTDR units. Such adaptability enables deployment strategies that align with existing network structures, thus helping to reduce deployment expenses.

Conclusion

The emphasis on lightweight solutions addresses outdoor site deployment challenges effectively. Reliable outdoor cabinets are crucial in challenging environments, minimizing maintenance costs in remote areas while facilitating cost-efficient and swift deployments in urban locales through resource reusability, scalable capacities, and versatile device integration.
Beyond these small-capacity outdoor OLT cabinets, ZTE also offers comprehensive FTTx series products spanning EMSs, cabinets, OLTs, ODNs, and ONTs, catering to the overall network construction needs of operators.
