GT-1205A

1-Port 10/100/1000Base-T – 2-Port Gigabit SFP Switch/Redundant Media Converter

Descrizione

Gigabit Ethernet Distance Extension

The GT-1205A directly converts the media from the Gigabit fiber to twisted pair interface. For example, it can be applied between the Gigabit Fiber Switch and the Gigabit Copper Network Card to perform media conversion and transmission.

With the conversion, you can easily have the transmission distance of Gigabit copper cable extended up to 550 meters or longer (depending on SFP module). Built in with two SFP ports, the GT-1205A can integrate with the existing copper switch to provide Gigabit fiber transmission without the need of replacing with the Gigabit Fiber Switch. With the Gigabit fiber transmission, the GT-1205A enables video stream to be delivered from the camera up to 120km away to local Network Video Recorder.

 

Fiber-Optic Networking for ISPs, System Integrators, Enterprises and Homes

With high performance of data transmission and easy installation, the GT-1205A can build the ISP network solution of FTTH (Fiber to the Home), FTTC (Fiber to the Curb) and FTTB (Fiber to the Building). The GT-1205A is also ideal for small office network environment of enterprises.

 

Fault Tolerant Redundant Link for Critical Network Applications

The GT-1205A is designed for optical fiber networks that require rapid link redundancy. With the auto-recovering feature, the redundant media converter responses rapidly for critical applications.
