GPON and EPON Comparison
PON Protocols
There are many PON protocols and standards defined by the ITU organisation with varying levels of maturity. The three main ones which are BPON, EPON and GPON. The main differences between them lie in the protocols used for upstream and downstream...

The SFP+ cable data transmission or distance is defined by the modal bandwidth of the module. For example, the Cisco 10GBASE-SR SFP module (SFP-10G-SR) is supported by a bandwidth of 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Once the bandwidth is increased to 4700MHz*km MMF (OM4),...

How to classify fibre optic cable?
It is a broad question.
a. By NEC - UL - flame retardancy;
b. By cable types (tight buffer/distribution/breakout/loose tube);
c. By fibre types:
Multimode fiber optic cable
Single-mode fiber optic cable
Hybrid fiber optic cable
d. Whether it has fibre and...

Although FTTx is now being widely applied, many places are not able to use optical fiber or FTTx. For example, CAT6 or CAT5e cables are still occupying a certain proportion comparing with fiber optic cables. In some places FTTx and CAT5e/CAT6 network cables are being operated at the same time. In...
