Optical switch

TFortis PSW-2G6F +

The main feature of the PSW-2G6F + switch is its support for dual PoE + technology (IEEE 802.3at), which makes it possible to power any PoE-camcorder using a standard Ethernet cable. It is implemented as follows. 30 W is transmitted through pairs of wires 1, 2 and 3, 6 (option A) and 30 W is transmitted through pairs 4, 5 and 7, 8 (Option B). As a result, 60W enters the load. This power scheme is supported by energy-intensive devices. For example, outdoor PTZ video cameras with a declared power of 60W. It is important that the device supports the operation of devices requiring conventional PoE (IEEE802.3af) with a consumption of up to 15W.

Built-in optical cross

The PSW-2G6F + switch has a design with an integrated optical cross. This allows you to weld optics directly into the switch housing. No need to put an external cabinet, which will save a lot.

Connecting devices in a chain

The presence of 2 gigabit ports allows you to connect the PSW-2G6F + to 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 / RSTP protocols is implemented. This makes it possible to lay additional communication channels between devices. In other words, each camcorder will have an alternative communication channel. 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-2G6F + connected in a chain.
