More info

AROONA-SMUX offers a flexible and low-cost solution to expand the capacity of existing multi-mode fiber links in Local Area Networks.

Using mode-group multiplexing over 4 optical channels, Cailabs’ unique Multi-Plane Light Conversion* technology transforms a single conventional multi-mode fiber link into 4 independent channels, equivalent to 4 single-mode fiber links.

By overcoming modal dispersion, reach for high transmission rates is increased by as much as 10 km [6.2 mi]. This enables duplex transmission up to 4 x 10+ Gb/s in only one pair of standard multi-mode fibers (OM) at a single wavelength.

AROONA-SMUX is a passive device and transparent to communication protocol. It operates with commercial singlemode transceivers at 1550 nm and achieves high transmission rates without additional optical fiber deployment. It offers a capacity increase without a hassle and for a low cost.

Typical use case

Let us consider a 300m [0.2 mi] link at 100 Mb/s over dual OM2 fibers between two buildings on a campus. Increasing data rate to 1 Gb/s can be achieved by upgrading active components such as switches and transceivers. However, an upgrade to 10 Gb/s is limited by the bandwidth of the OM2 fibers.

Increasing the data rate to 10 Gb/s typically requires the deployment of new fibers.

AROONA-SMUX solution increases the capacity of the link up to 4 x 10+ Gb/s without long, complex and expensive fiber deployment. AROONA-SMUX is also compatible with WDM technologies, providing easy and seamless high-capacity scaling of the network while ensuring LAN infrastructure durability.
