Optical Port Switch

5-port psw-2g switch example

Gigabit Ethernet ports are designed to connect to the trunk network and are made in the form of SFP slots. The user has the opportunity to independently choose the most suitable SFP module for him or use the SFP module we offer. To work with PSW-2G optics, it is recommended to use FC-1G media converter.

Powering the camcorder and the thermal jacket by PoE

The device has 3 ports for connecting cameras. These ports are equipped with a PoE injector, which allows you to remotely power both the camcorder and the thermocouple using a standard 4-pair twisted pair cable. Data transfer, power of the camera and the thermal jacket – everything will go through one cable. You no longer have to lay an additional power cable to the camcorder. This will allow you to save on materials and work. And even if there will be power in the places where the cameras are installed, problems may arise with the legalization of its use (you need to set up a counter, make approvals, etc.). Using PSW-2G, you get away from the above problems and costs. With the PSW-2G, you will install camcorders where they need to be installed, and not where they work.

Uninterruptible power for camcorders

If you connect the PSW-2G through an uninterruptible power supply, then, due to PoE power supply, you will simultaneously provide backup power to the camcorders themselves. Please note that the PSW-2G has two power supplies. The first PSU is designed to power the switch itself and video cameras, and the second – to power the thermal housings. Since PSUs have separate terminals, it is advisable to connect only the first PSU through an uninterruptible power supply. When switching to an uninterruptible camera, the cameras will continue to work, and the heating will turn off. This will allow the system to work longer on the battery, and the heat dissipated by the camera is enough not to freeze during this time.

Connecting devices in a chain

The presence of 2 gigabit ports allows you to connect the PSW-2G in the “chain”. In this case, only one optical fiber is used. This is especially true when communication lines are leased or there is a shortage of free optical fiber fibers.

Building a fault tolerant network (STP / RSTP)

To ensure a fault-tolerant network, support for the STP / RST protocols is implemented. This makes it possible to lay additional communication channels between devices. In the event of a break in the optics or failure of a network node, the traffic will go along alternative routes. The recommended scheme is a “ring” with RSTP protocol.

Gigabit bandwidth

Gigabit speeds allow you to pump the total traffic even from powerful cameras even when you connect them to the PSW-2G, connected in a chain.
