Wavelength       : 1310/1490nm

Distance            : 20km




CRED’s GPON-ONU-SFP-KCSM series transceiver is a high performance module for single fiber communications using a 1310nm burst- mode transmitter and a 1490nm continuous-mode receiver. It is used in the optical network terminal (ONT) for GPON ONU Class B+ applications with Mac inside.

The Transmitter is designed for single mode fiber and operates at a nominal wavelength of 1310nm. The transmitter module uses a DFB laser diode with full IEC825 and CDRH class 1 eye safety.

The receiver section uses a hermetic packaged APD-TIA (APD with trans-impedance amplifier) and a limiting amplifier. The APD converts optical power into electrical current and the current is

transformed to voltage by the trans-impedance amplifier. The differential DATA and /DATA CML data signals are produced by the limiting amplifier.

CRED SFP transceiver could compliant with most of word brand products, like Cisco, Finisar, HP, Ericsson, Nortel Arista, Juniper, Extreme, Allied Telesis, Foundry, Force10, Alcatel-Lucent…and more.
