GPON and XG-PON1 Transmission Rates

GPON is inheriting lots of specifications from BPON. Signal is broadcasted downstream in the same manner. Upstream signal is relying on TDMA, the same way as it was in BPON. Most of other inherited specifications were enhanced – GPON is supporting higher rates, better security, increased bandwidth and etc.
 

Table 1. GPON and XG-PON1 Transmission Rates

 

Downstream (Gbps) Upstream
1.24416 155.52, 622.08, 1244.16 Mbps
2.48832 155.52, 622.08, 1244.16, 248, 832 Mbps
9.95328 2.48832 Gbps

 

GPON and XG-PON1 transmission rates are shown in Table 1. IT is achieved by using large, variable length packets.

 

GPON encapsulation method (GEM) helps to improve QoS for video and voice traffic by reducing latency. It happens due GEM’s user traffic aggregation and frame segmentation.

Testimonials

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
