Cisco - QSFP28 transceiver module - 100GbE

The Cisco QSFP-100G-SR1.2 BiDi is a parallel Quad Small Form-factor Pluggable (QSFP28) Bi-Direction optical module that supports 100 Gbps bit rates. The module integrates four host electrical data into two optical lanes over a 2-fiber duplex LC optical multi-mode fiber. The QSFP 100G SR1.2 BiDi operates 50Gb PAM4 channels, for a total aggregate bandwidth of 100Gb. PAM4 technology enables 50Gb data rate with signaling at 25Gbaud rates. Reversely, on the receiver side, the module de-multiplexes 2 sets of optical input signal and converts them to 4 channels of electrical data. An optical fiber ribbon cable with an LC connector can be plugged into the QSFP28 module. The QSFP 100G SR1.2 BiDi is compliant to IEEE802.3bm 100GBASE-SR4.The Cisco QSFP-100G-SR1.2 BiDi transceiver will operate with a Cisco QSFP-100G-SR1.2 BiDi for 100G connectivity. It can also connect to a Cisco 400 Gbps SR4.2 BiDi in a 4 x 100G breakout mode. The Cisco QSFP-100G-SR1.2 BiDi will not interoperate with the Cisco QSFP-40/100-SRBD.
