The IBM QSFP+ Transceivers are 40GBase-eSR4 Transceiver module (00FE325) of hot-pluggable (eSR4) nature. These transceivers plug into a SERDES data port. IBM QSFP+ transceivers deliver 40GbE connectivity in configuration of 4 x 10 Gigabit Ethernet ports compliant with IEEE 802.3ba -2010 standards. IBM QSFP+ Transceivers from Cozlink deliver 10Gbps connectivity up to a distance of 550 m at the input frequency of 850nm on a multimode fibre. These high speed interconnects from Cozlink are applicable across 40GBASE-eSR4 applications and are operational at 0-70 degree Celsius of industrial temperature range. Cozlink manufactures 10GBASE-LR and other long range connectivity QSFP+ Transceivers also and all of these comply with RoHS and QSFP+ MSA standards. These transceivers can be fully interchanged with other QSFP+ transceiver brands such as Finisar, Brocade, Dell, Cisco, Huawei, Juniper, and HP etc.
