EPON OLT Optical Transceiver - 1.25Gbps SFF Module

This device is a high-performance integrated single fibre bi-directional optical transceiver. It has a 1310nm Burst-mode PIN/TIA receiver and a 1490nm DFB laser transmitter.

This EPON OLT Transceiver module is designed for Gigabit Ethernet Passive Optical Networks (EPON) 10km transmission. The module incorporates a 1490nm continuous-mode transmitter and a 1310nm burst-mode receiver.

The transmitter uses a 1490nm DFB laser and an integrated laser driver that is designed to be Class1 eye safe under any single fault event. The laser driver includes automatic power control and temperature compensation circuit, which keep the optical power and extinction ratio constant over the temperature variation and ageing process.

The receiver uses an integrated 1310nm InGaAs PIN photodiode and BM-preamplifier mounted together. The burst-mode receiver is resetless and has wide dynamic range over 21dB can be obtained under all operating conditions. The module has a function to indicate receiver signal-detected status (active high).

An integrated WDM coupler separates the 1490nm output light and 1310nm input optical signal.

The metallic package guarantees excellent EMI and EMC characteristics, which completely comply with required international standards.
