40G Dual Port Single Mode
產品描述
The 1300nm 40G Dual QSFP+ LR4 quad port bypass module is designed as alternative 40Gbps dual QSPF+ LR4 transceiver. Its innovated design able the fiber bypass function become selectable within single PCI card. The 1300nm 40G Dual QSFP+ LR4 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 10Km using Single Mode fiber(SMF). The optical interface uses a Dual-LC connector.

1. Output power is power couples into a 9/125um Single-mode fiber (SMF).
2. Hit ratio= 5×10E-5 per sample.
3. Measured with 10.3125Gbps of PRBS-31 at 10-12 BER.
4. Normal Mode (Bypass Mode Off).
5. Bypass Mode (Normal Mode Off).
6. Minimum value is informative.
7. RIN is scaled by 10*log(10/4) to maintain SNR outside of transmitter.
8. Minimum value is informative, equals min TxOMA with infinite ER and max channel insertion loss.
