Commonly found in fibre optic networks, hiphotonics' 4-port optical circulator is used to transmit signals from one port to another, in a designated sequence. Being a non-reciprocal device, the signal can only pass across the ports in a designated direction. The gadget comprises of a ferrite magnet that rotates the polarisation of the entering light thereby guiding it to the suitable output port.
The compact size of the 4-port optical circulator is a notable characteristic that makes it perfect for usage in tight quarters. It also has optical amplification, which makes sure the signal gets where it's going as efficiently as possible by increasing its strength as it goes through the gadget.

Additionally, the device exhibits low insertion loss, indicating that there is minimal signal loss as it travels through the circulator. In metropolitan area networks, where devices can be located at considerable distances and a strong signal is absolutely necessary, this is of utmost importance.

Low polarisation dependence loss (PDL) is another feature of the 4-port optical circulator; so, the polarisation of the arriving light has no effect on the signal. This is significant since any change in polarisation results in signal loss and polarisation might change as it passes through the fibre.

Another function of the 4-port optical circulator is dynamic gain equalising, which guarantees balanced signal levels across the device. In high-performance networks, this is crucial since even minute changes in signal strength can influence general performance. 

With advanced dispersion adjustment that improves its performance in high-speed networks, the gadget is quite stable and dependable. Its low insertion loss and great channel isolation help to produce a high-quality signal with minimum degradation.

At last, the 4-port optical circulator is epoxy-free, thereby guaranteeing that the optical route is free from elements capable of compromising the signal quality. In laboratory research and development, this is a perfect tool since accuracy is of great relevance.

Highly sophisticated and with a range of characteristics fit for application in many environments, the 4-port optical circulator is Delivering high-quality performance with low signal degradation, its small package size, low insertion loss, and high-stability make it the perfect device for usage in metropolitan area networks and laboratory research.
