Support network applications such as 40G Ethernet and OTU3.
Single-mode optical fiber supports a transmission distance of up to 40km.
Built-in DDM (digital diagnostic monitoring function).
Working temperature: 0°C ~ +70°C.
Comply with RoHS standards.
The 40G QSFP+ optical communication module launched by Sintai Communication Co., Ltd. is specifically designed for 40G Ethernet and 40G OTN applications.
The module conforms to the QSFP+ MSA standard and IEEE 802.3ba standard ad supports a maximum rate of 44.6Gb/s, with digital diagnostic capabilities.
The product contains two kinds' modules: single-mode module and multimode module.
The single-mode module is equipped with MUX/DEMUX devices, and it uses wavelength division multiplexing technology to multiplex the 4 x 10Gb/s CWDM channel on a single optical fiber, with the longest transmission distance of up to 40km. It's widely used in environments such as large data centers, campus networks, metro networks, etc.
