Shanghai Baudcom Communication Device CO.,LTD

Description
The 2 PON Amplifier Range Extender from BAUDCOM is an optical transmission device that magnifies and reshapes signals throughout the transmission process. The GPON Amplifier Range Extender may significantly reduce OLT consumption while also increasing network transmission distance. GPON Amplifier has been widely used in many optical communication applications for long-distance transmission. Its benefits include tiny optical signal sizes, cost-effectiveness and safety, and ease of installation, among others. As a result, the PON Amplifier Range Extender may be used in a variety of optical transmission applications.

Features
1.The GPON repeater support four SFP slots(two OLT slots and two ONU slots);
2.In accord with ITU-T G984.x & ITU-T G.988 and Chinese communication industrial standard (YD/T 1475-2006);
3.Extend GPON system transmission distance more than 50km;
4.Uplink: supports combination of different types of PON OLT interfaces and different physical connectors;
5.Downlink: supports different types of PON ONU　interfaces (shunt or ONU interface).
6.Be compatible with GPON system;
7.Be compatible with GPON OLT and ONU equipment manufactured by different vendors;
8.1U desktop equipment, small space occupation and low power consumption;
9.Supporting GPON OEO relay function
10.Supporting 1550nm and 1620nm dual wavelength storage with externally connected passive equipment

PON technology has been applied more and more widely in the domains of private network communication such as electric power, coal mining, broadcast and television, and army. As we know, the transmission distance in a PON system is restricted within 20km scope. Owing to the restriction of OLT transmission distance, the quantity of ONU devices has to be reduced in order to lengthen the transmission distance, which results in great waste of OLT interfaces and optical fiber resources occupied by OLT. Furthermore, the optical power is often small but the transmission distance typically exceeds 20km in these applications, in particular, the optical fiber resources may very possibly become inadequate at the entrances of optical fiber to communities or key clients. Baudcom GPON repeater can easily resolve the above PON transmission problems.
