200G QSFP-DD SR8 TO 2x100G QSFP28 SR4 Breakout 有源光缆

Description:
F-tone Networks 200G QSFPDD To 2x100G QSFP28 breakout Active Optical Cable (FTQD-2H-SR8-2Q2-Oxxx ) is designed for short-range multi-lane data communication and interconnect applications. It integrates eight data lanes in each direction with 8×25.78125Gbps bandwidth. Each lane can operate at 25.78125Gbps up to 70 m using OM3 fiber or 100 m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 76 contact edge type connector. The optical interface uses a 24 fiber MTP (MPO) connector. This module incorporates F-tone Networks Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.

Features:
● Hot-pluggable QSFP DD/QSFP28 form factor
● 8 channels full-duplex transceiver module
● Supports data rate up to 26Gbps per channel
● 8 channels 850nm VCSEL array and PIN photo-detector array
● Internal CDR circuits within receiver and transmitter data paths
● Supports CDR bypass via I2C controlled
● Low power consumption: 200GBASE-SR8 QSFP DD＜4W and 100GBASE-SR4 QSFP28＜2.5W
● Maximum link length of 70m on OM3 MMF and 100m on OM4 MMF
● Single MTP/MPO receptacle
● Built-in digital diagnostic monitoring functionality
● I2C management interface
● Single 3.3V power supply
● RoHS 2.0 compliant (lead free)
● Case operating temperature
     Commercial: 0 ~ +70℃
     Industrial: -40 ~ +85℃

Applications:
● IEEE 802.3cd 200GBASE SR8
● IEEE 802.3bm 100GBASE SR4
