The 40G QSFP+ BiDi transceiver has two 20G channels that support connections up to 100 meters on OM3 MMF and up to 150 meters on OM4 MMF. It uses an LC Duplex connector and the wavelength is 850nm. The Cisco ® 40GBASE QSFP (Quad Small Form-Factor Pluggable) portfolio offers customers a wide variety of high-density and low-power 40 Gigabit Ethernet connectivity options for data center, high-performance computing 00networks, enterprise core and distribution layers, and service provider. The Cisco® 40GBASE QSFP (Quad Small Form-Factor Pluggable) portfolio offers customers a wide variety of high-density and low-power 40 Gigabit Ethernet connectivity options for data center, high-performance computing 00networks, enterprise core and distribution layers, and service provider. QSFP-40G-SR-BD is a 40G QSFP+ BiDi transceiver designed for short-reach connectivity over duplex multimode fiber using LC connectors. It enables 40GbE transmission with only two fibers, making it a practical alternative to QSFP-40G-SR4 in environments where fiber resources are limited or MPO. BiDi transceiver, a compact optical transceiver with WDM (wavelength division multiplexing) technology and SFP multi-source protocol (MSA) compliance, allows fast data transmission using a single fiber optic for both sending and receiving signals, saving resources and cutting infrastructure costs. For distances exceeding 40km, the wavelength. The YXF-QP-M85L-01D is a four-channel pluggable LC duplex QSFP+ fiber optic transceiver for 40 Gigabit Ethernet applications.
