Description
DELTA’s high capacity GPON ONU transceiver
module is designed for Passive Optical Network
(PON) application, 2.488Gbps downstream and
1.244Gbps upstream. It is compliant with ITU-T
G.984.2 standard.
The GPON ONU transceiver is provided with SC
pigtail connector complied with SC connector
industry standard.
The module consists 1310nm un-cool DFB laser,
InGaAs/InP APD, Preamplifier and WDM filter in a
high-integrated optical sub-assembly, and it
receives up to 2.488Gbps of continuous data at
1490nm, and transmits 1.244Gbps of burst-mode
data at 1310nm.
