Description
DELTA’s GE-PON ONU transceiver
OPEP-33-A4K3R is designed for Gigabit Ethernet
Passive Optical Network transmission.
The module is contained in a 2x5 SFF
package with a 9/125um SC pigtail single mode
fiber.
The module consists 1310nm DFB laser,
InGaAs PIN, Preamplifier and WDM filter in a
high-integrated optical sub-assembly, and it
receives up to 1.25Gbps of continuous data at
1490nm, and transmits 1.25Gbps of burst-mode
data at 1310nm.
