SFP+ / QSFP28 – Компания «Т8». DWDM-системы

SFP+ / QSFP28

First Russian transmit-receive modules T8 LLC and Fiber Trade LLC joint manufacture

Optical transceivers consist of changeable modules, designed for different parameters of transmission lines and inserted in standardized electrical ports of active equipment. It allows optimizing outlays during the designing and especially during the reconstruction of optical networks.
Transceivers are designed to convert electrical signals in optical ones and following transmission using fiber-optical line and further optical-electronic conversion on the reception.
T8 company in conjunction with Fiber Trade LLC developed transceiver modules form factor SFP (SFP+LR and SFP+DWDM) with a transmission rate up to 11.3 Gbit/s and form factor modules QSFP (QSFP28) with the transmission rates up to 103 Gbit/s.
