Pluggable or QSFP+ Module supports link lengths

The  Optowiz  QSFP+ converts parallel electrical input signals  into parallel optical signals, by  a
driven  Vertical Cavity Surface Emitting Laser (VCSEL) array. The transmitter module accepts  the functional block diagram of the Optowiz QSFP+ Transceiver. Compare with 10Gpcs’s serial solution, the new QSFP+ solution may over doubled the slot for each connection, and save power consumption over. This product is wildly apply in the area of cloud calculating, date center, Enterprise network, telecom and Server. The new QSFP is adapt for both short haul and long haul
The Cisco 40GBASE-CSR4 QSFP+ Module is similar to the 40GBASE-SR4 interface extends supported link lengths to 300m and 400m respectively on laser-optimized OM3 and OM4 multimode fiber cables. Each 10-gigabit lane of this module is compliant to IEEE 10GBASE-SR specifications. This module can be used for native 40G optical links over 12-fiber ribbon cables with MPO/MTP connectors, or in 4x10G mode with ribbon to duplex fiber breakout cables for connectivity to four 10GBASE-SR interfaces. Maximum channel insertion loss allowed is respectively 2.6dB over 300m of OM3 cable or 2.9dB over 400m of OM4 cable.
