Growing data volumes = growing costs. But it doesn't have to be that way.
The growing demand for data means increasingly higher monthly operating expenses (OPEX).
A proprietary transmission layer based on xWDM S100 shifts costs to a predictable capital expenditure (CAPEX).
You gain full control over connections and SLAs, the ability to scale within existing fibers, and a stable budget over time.
For whom GBC Photonics S100?
DWDM in S100 allows you to “pack” significantly more optical channels onto a single fiber, thanks to very dense wavelength division. This means greater bandwidth and scalability than CWDM. If CWDM is a “highway with wide lanes,” S100 is a highway with more lanes, but still safe for traffic.
If you have cheap and available fiber, sometimes yes. But in practice, fiber is usually expensive, difficult to lease, and often simply unavailable in large cities. S100 allows you to increase bandwidth on what you already have. That means less digging and paperwork, and more power in your existing infrastructure.
Standard DWDM requires optical power budget planning, OTDR verification, and dispersion consideration. The S100 makes it easier:
– it has ready-to-use plug & grow modules,
– it provides real-time monitoring of OSNR, power, and waves,
– it provides alarms and <50 ms response time in case of failure.This means that integrators do not need to be “optical physicists” to implement the system.
Yes. It was created precisely for such customers. The S100 eliminates the need to lease multiple fibers—often the biggest expense. For integrators and end customers, this means cheaper implementations and stable costs in the coming years.
By default, the system uses one pair of fibers. In some scenarios, a single-fiber configuration can be used, but this depends on the project – the Salumanus team will help you choose the right option.
Not all of them. The S100 supports classic duplex solutions and BIDI (single-fiber) modules. The choice depends on the network architecture and fiber availability. It is worth asking about this during the design phase, as it can reduce costs by up to half.
No. The S100 operates on a “plug & grow” model. You can start with a small configuration (e.g., a few channels) and add more modules as your needs grow—without replacing the entire platform.
– You have full control over the data route – no intermediaries.
– You can separate critical traffic (e.g., banking systems, monitoring).
– The system is redundant and responds to failures in <50 ms, eliminating downtime.
No. This is where the S100 has an advantage – integrators can install and launch the system without months of training. The management panel is intuitive, and Salumanus provides support covering design, module selection, and testing.
The cost depends on the configuration, but the model is simple: instead of increasing OPEX (fiber lease), you invest in CAPEX, which pays for itself. Most often, the return on investment occurs within 12–24 months, and then the network “pays for itself” without additional fees.
– Integration of multiple university buildings, government offices, and banks.
– Connecting server rooms and data centers.
– CCTV and video surveillance in cities.
– ISPs that want to provide services without new investments in fiber optics.
Yes – the DWDM architecture in S100 is compatible with security layer solutions, including QKD systems. If the customer has such requirements, the Salumanus team can select the appropriate integration.
We will select a solution that will be an investment, not an expense.
