Migrating to 400G? Choosing the Right OptionAs customers deploy 400G connectivity, they are transitioning from 25/100G connectivity to 100/400G connectivity for the different tiers of the network. Before making a decision, you should carefully consider your technical needs and budget with these parameters in mind: Reach: the distance you need to transmit dataPower ConsumptionFlexibility – bending ratio. This is particularly important in tight spacesCost Let us l

50G transceiver modules are available in the SFP56 and QSFP28 form factors. The differences are the electrical signal and size. A 50G QSFP28 uses 2 of the 4 available electrical lanes (Electrical I/O) on a QSFP connector, with each lane running at 25Gbs NRZ. A 50G SFP56 uses 1 x 50Gbs PAM-4 lane (26.5625Gbaud/s). Both use PAM4 modulation for the optical signal. The SFP56 module is slightly smaller in size than a QSFP28 and allows for hi

E.C.I. NETWORKS (ECIN) is pleased to announce the Company has joined the Open Compute Project (OCP) as a Community Member.More than three years ago, ECIN, a System Integrator, started to deliver the Open Networking solutions with the network optics you need for tomorrow’s Data Centers, Wired and 5G Wireless Networks. The Open Compute Project (OCP) is a collaborative community focused on redesigning hardware technology to efficiently support the growing demands on compute infrastructure.Join

Wedge100BF has two BIOS ROMs:One on the COMe module, called "main BIOS", and an "external" one on the Wedge mainboard, called "external BIOS". The external BIOS can be accessed via BMC SPI interface.(1) Use the external BIOS flash chip to boot COMe.root@bmc:~# source /usr/local/bin/openbmc-utils.sh<br>root@bmc:~# gpio_set BRG_COM_BIOS_DIS0_N 1<br>root@bmc:~# gpio_set BRG_COM_BIOS_DIS1_N 0Make sure the external BIOS connects to COMe instead of BMC.root@bmc:~# gpio_set COM6_BUF_EN 0&lt
