Product Descriptions
The QSFP+ SR is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for 40 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 40 Gbps bandwidth.one version is Each lane can operate at 10.5Gbps up to100m using OM3 or 150m using OM4 Multimode fiber,another version is Each lane can operate at 10.5Gbps up to300m using OM3 or 400m using OM4 Multimode fiber These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses an 12 fiber MTP (MPO) connector. This module incorporates proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
