EPON OLT sfp fiber optic transceiver 1.44Gbit / s downstream 1.244 Gbit / s upstream

Specification:

20km EPON OLT Optical Transceiver SFP Module 1.44Gbit/s downstream 1.244 Gbit/s upstream

Description:

The EPON OLT Transceiver module is designed for Gigabit Ethernet Passive Optical Network(EPON)20km transmission. The module incorporates 1490nm continuous-mode transmitter and 1310nm burst-mode receiver.

The transmitter section uses a 1490nm DFB laser and a integrated laser driver which is designed to be class1 eye safe under any single fault. The laser driver includes APC and temperature compensation circuit, which are used for keeping the launch optical power and extinction ratio constant over temperature and aging. The receiver section uses an integrated APD and BM-preamplifier mounted together. The burst-mode receiver is resetless and wide dynamic range over 20dB can be obtained under whole operating conditions. The module has the function that indicates receiver signal-detected status (active high).

An integrated WDM coupler can separate 1490nm output light and 1310nm input light.

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