40G Dual Port Multi Mode
Product description
The 850nm 40G Dual QSFP+ SR4 quad port bypass module is designed as alternative 40Gbps dual QSPF+ SR4 transceiver. Its innovated design able the fiber bypass function become selectable within single PCI card. The 850nm 40G Dual QSFP+ SR4 quad port bypass module is design expressly for Intrusion Prevention System (IPS) provides complete visibility to network traffic, It also introduces a point of failure should the IPS lose power, cable fail or application freeze.
This interconnecting system include dual ways transceivers offers 4 channels and maximum bandwidth of 40Gbps. It integrates four data lanes in each direction with 40 Gbps aggregate bandwidth. Each lane can operate at 10.3125 Gbps up to 100 m using OM3 fiber or 150 m using OM4 fiber. The optical interface uses a 12/8-fiber MTP® (MPO) connector.
