SANWA offers various PLC (Planar Lightwave Circuit) splitters, a key component in FTTH (Fiber to the Home) networks, enabling the distribution of optical signals from a single input to multiple outputs. Constructed from high-quality silica glass, these splitters provide superior performance metrics such as low insertion loss, typically less than 0.3 dB, and consistent splitting ratios across all output ports. This ensures equitable distribution of data to all endpoints in a network.

The splitters operate over a broad wavelength range, typically from 1260nm to 1650nm, making them versatile for various applications. They are temperature-resistant, functioning reliably within a range of -40°C to 85°C. This durability translates into long-term reliability, even in harsh environmental conditions.

PLC Splitters

Equipped with industry-standard connectors and adapters, such as SC, LC, or FC, the SANWA PLC splitters are easily integrated into existing fiber networks. Their compact form factor and modular design allow for convenient installation in various enclosure types, from wall-mounted boxes to rack-mounted panels.

The splitters are based on plasma chemical vapor deposition technology and a patented fabrication process. They offer stable performance, high reliability, and specifications that exceed Telcordia requirements. The splitters are available in different configurations from 1x2 to 1x64 and 2x2 to 2x64. The specifications include insertion loss, loss uniformity, return loss, polarization-dependent loss, directivity, and wavelength-dependent loss. The splitters come in a bare package, blockless package, and with different fiber connectors and fiber types. They operate within a wavelength range of 1260 to 1650nm and a temperature range of -40 to 85 degrees Celsius. Custom specifications are also available.

PLC Cassette and Rack-Mounted

PLC Cassette and Rack-Mounted

PLC Cassette and Rack-Mounted configurations in telecommunications are standardized solutions that allow efficient use of space and provide ease of integration within data centers and telecom closets. Incorporating devices like WDM, Splitters, and AWGs into a 1U rack-mount configuration not only promotes efficient space utilization but also ensures that networks can be customized, scaled, and maintained with ease. It is a win-win for both operators and users.

The SANWA splitters come in different cassette types and sizes depending on the number of ports. They have various connector and adapter options and fiber cable lengths. Custom solutions are also available.
