vOLT64 Entry-level All-Optical Network The Preferred All-Optical Solution for Small and Medium Projects

AINOPOL – Provider of All-Optical Converged Solutions

Do small projects also need optical network upgrading?The vOLT64 turns ordinary switches into GPON OLT devices in seconds.No dedicated chassis is required — a single SFP+ module completes the entire all-optical upgrade.

Scenarios such as small and medium-sized campuses, office buildings and hotels want to build all-optical networks, yet traditional OLT devices are expensive and complicated to deploy.

AINOPOL vOLT64 (Model: ZH-VOLTXG64) can be directly inserted into existing switches or routers equipped with SFP+ optical ports (supporting forced 2.5G rate). It upgrades common Ethernet equipment into a complete Passive Optical Network (POL) central office device.

It supports 2.5G downstream and 1.25G upstream, connects up to 64 XGONU terminals, with a maximum transmission distance of 20 km, and power consumption of the single module is no more than 5W.This article details how the vOLT64 transforms all-optical network deployment from a large-scale project into a simple plug-in module solution.

Opening the Door of All-Optical Networks for Small & Medium Projects

Traditionally, deploying an all-optical network or POL solution means purchasing large chassis-based OLT devices, which often cost tens of thousands of yuan and require professional optical network engineers for commissioning.

As a result, numerous small and medium projects with 50 to 200 network points — including chain hotels, medium and small office buildings, industrial parks, factory dormitories and smart farms — can only continue using traditional copper cable solutions.

The vOLT64 is designed to break this barrier, making all-optical networks no longer exclusive to large enterprises and high-budget projects.

Three Major Barriers to All-Optical Network Implementation for Small & Medium Projects

How vOLT64 Breaks Down Traditional Barriers One by One

Low Cost: Pay-as-you-go, Plug and Play

The vOLT64 is a module-type OLT packaged in SFP+ form factor.With dimensions of only 78×49×21 mm, it can be directly inserted into the 10G SFP+ port of any existing switch, router or firewall.

Once installed, it functions as a complete GPON OLT central office device, providing an independent virtual PON port.This means users with existing network equipment do not need to replace their current hardware. By simply adding one module, they can smoothly upgrade to an all-optical network architecture.

Enterprises can purchase one or multiple modules according to project scale, truly realizing buy only what you need, and greatly lowering initial investment costs.

Zero Threshold: Automatic Registration with Zero Configuration

Traditional OLT deployment requires engineers to perform extensive CLI configuration via serial ports or network management, including ONU registration, service flow binding, and VLAN division.

The vOLT64 is built with automatic registration. After power-on, ONU terminals can be automatically identified and bound by the vOLT module.It transparently forwards default VLAN tags and supports full penetration of unicast, multicast and broadcast data, enabling zero-configuration deployment.

System integrators and weak-current construction personnel can install it just like a regular optical module. No professional optical network engineer is required, and deployment can be completed independently.

Excellent Compatibility: Supports Mainstream Third-Party HGU ONUs

Complying with standard GPON protocols, the vOLT64 is compatible with most third-party HGU-type GPON terminals on the market, with a compatibility rate up to 95%.

This gives integrators great flexibility in terminal selection. They can deploy AINOPOL’s own XGPON terminals, or adopt compliant ONUs from other brands, avoiding vendor lock-in.

High Performance: Gigabit to the End, Meeting Demand for the Next 5–10 Years

The vOLT64 delivers 2.5G downstream / 1.25G upstream rate, supports single-mode fiber transmission up to 20 km, and allows access to a maximum of 64 ONU terminals.

The single-module power consumption is ≤5W. Featuring an efficient heat dissipation design, it operates stably in a wide temperature range of -40℃ to 85℃.

Adopting standard GPON and Ethernet switching protocol stacks, it efficiently supports integrated bearing of video, voice and data multi-services.

Take a 100-room hotel as an example:If the existing core switch is equipped with SFP+ optical ports, the IT team only needs to insert one vOLT64 module — no additional central office equipment is required.

Install passive optical splitters (1:8 or 1:16) in weak-current closets, and lay optical fibers from splitters to each guest room. Deploy GPON ONU terminals in every room to provide Wi-Fi coverage, TV services, telephone lines and intelligent room control interfaces.

Thanks to the vOLT64’s automatic ONU registration, construction staff only need to connect the optical fiber on-site. Terminals will be automatically identified after power-on, greatly shortening the project cycle and reducing reliance on professional technicians.

vOLT64: The Gateway to All-Optical Networks for Small & Medium Projects

Only when fiber-to-the-room, POL passive optical networks and GPON solutions are no longer expensive and complicated can all-optical technology truly penetrate segmented markets.

The vOLT64 is a key driver of this popularization trend.It enables system integrators to bid for and construct all-optical projects with low cost and low risk, while allowing end users to enjoy high-speed, stable gigabit fiber network experience with far less investment.

FAQ

Q: What is the difference between vOLT64 and traditional large-scale OLT?A: Traditional OLTs are large chassis devices with high cost, bulky size and complex deployment.The vOLT64 is a module-level, plug-and-play device that works directly with ordinary switches. It significantly lowers deployment barriers and costs, making it ideal for small and medium projects.

Q: Can vOLT64 work with my existing switch?A: In principle, it supports any switch with standard 1G SFP ports.Although packaged in SFP+, it is backward compatible with 1G SFP interfaces. With well-controlled power consumption, it offers good compatibility with mainstream switch electrical ports.

Q: How many ONUs can it support simultaneously?A: The vOLT64 supports up to 64 GPON ONU terminals online concurrently, suitable for small and medium projects with 50–200 network points.For larger scale scenarios, you can add more modules or adopt traditional chassis-style OLT.

In accordance with ITU-T G.984 series international standards, GPON technology defines a maximum fiber differential distance of 20 km and a rate of 2.5Gbps downstream / 1.25Gbps upstream, making it a mainstream global fiber access standard.

Issued by the Ministry of Industry and Information Technology of China, industry standards YD/T 6442-2025 Technical Requirements for Broadband Customer Network Interconnection over Public Telecommunication Networks — Fiber to the Room — Management and YD/T 6443-2025 Technical Requirements for Broadband Customer Network Interconnection over Public Telecommunication Networks — Fiber to the Room — Residential Equipment provide national standard basis for the design, R&D and management of fiber-to-the-room networks.

Deploying an all-optical network with the international and national standard compliant vOLT64 is a reliable and compliant path for small and medium projects to adopt POL passive optical networks and realize fiber-to-the-room deployment.
