GPON OLT SFP Class C+++ 7dBm Transceiver Modules
Description
The GIGAOPTO's GTS-SGT21-20DCE is a high performance transceiver module for single fiber communications using a 1490nm continuous-mode transmitter and a 1310nm burst-mode receiver. It is designed to meet ITU G.984.2 Class C++ requirements for optical line terminal (OLT) applications.
The 1490nm DFB LD transmitter has automatic power control (APC) function and temperature compensation circuitry to ensure stable optical power and extinction ratio over all operating temperature range. The transmitter meets Class 1 eye safety per IEC60825 and CDRH standards.
The receiver has a hermetically packaged APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with LVPECL compatible differential outputs. It features a Burst Packet Detect (SD) output which is LVTTL compatible. The SD output will come high after receiving the burst packet.
The module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias current, module temperature, and supply voltage. Calibration and alarm/warning threshold data are written and stored in the internal memory (EEPROM).
This SFP transceiver module has done sampling test under most famous brands of routers, switches, servers.
The hot swappable GPON SFP transceiver is ideal for Internet Service Provider (ISP) Gigabit Passive Optical Network (GPON) communication links, other optical links.
