Introduzione

The QSFP28 40/100G dual-rate BiDi (Bi-Directional) transceiver is a pluggable optical transceiver with a duplex LC connector interface for short-reach data communication and interconnect applications using MMF. It offers customers a solution that enables reuse of their existing 10 Gb duplex MMF infrastructure for migration to either 40 or 100 Gigabit Ethernet connectivity.
In 40G mode, the Cisco QSFP 40/100G BiDi transceiver supports link lengths of 100m and 150m on OM3 and OM4 MMF, respectively. In 100G mode, it supports 70 and 100 meters on OM3 and OM4, respectively. Each 40/100G BiDi transceiver consists of two transmit and receive channels in the 832-918 nm wavelength range, enabling an aggregated 40G or 100G link over a two-strand multimode fiber connection.
In 100G mode, the operating temperature range is +10 to +60°C and in 40G mode it is +10 to +70°C. the QSFP28 40/100G BiDi module is primarily used in data center and enterprise applications.
