Hello Readers, Below down we are going to talk about Classification of PON Modules and will try to describe you easily.
(1) OLT optical module and ONU optical module: According to the different classification of plug-in devices there are two types of PON optical modules: OLT optical module (this module is mainly inserted into the OLT end, and cannot be shared with the ONU optical module) and ONU (this module is mainly inserted into the optical network unit) optical module. SFP package.
Note: OLT optical modules are more complex than ONU optical modules, because each OLT optical module must be able to transmit signals with a maximum of 64 ONU optical modules.
(2) The difference between GPON optical module, EPON optical module and APON optical module. According to the different classification of technical standards (ie transmission protocols), PON optical modules can be divided into four types: APON is ATM PON, BPON is broadband passive optical network, EPON is Ethernet passive optical network and GPON is gigabit passive optical network. type EPON and GPON.
EPON optical modules are available in SFP, XFP and SFP+ packages, with a transmission distance of up to 20km, and the receiver part has a sealed preamplifier and a limiting amplifier with LVPECL compatible differential output.
GPON optical module is a high-performance and economical optical module for serial optical data communication applications of 2.5Gpbs (downlink can reach the highest rate). The advantage of this optical module is that it can guarantee no eye damage in any fault condition harm.
The above is the classification explanation of PON modules brought to you by Shenzhen HDV photoelectric Technology Company Ltd., The module products produced by the company cover optical fiber modules, Ethernet modules, optical fiber transceiver modules, optical fiber access modules, SSFP optical modules, and SFP optical fibers. modules, etc. The above module products can provide support for different network scenarios.
