Can the QDD-200G-SR8 and Q56-200G-SR4 be used interconnected?

No. The QDD-200G-SR8 is an 8-channel transceiver with MTP/MPO-16 interface, while the Q56-200G-SR4 is a 4-channel transceiver with MTP/MPO-12 interface, which are different in the number of channels and modulation modes, and cannot be interconnected.

What application scenarios are there for the QDD-200G-SR8?

QDD-200G-SR8 is mainly used to connect to two 100G QSFP28 SR4 optical modules with branch patch cords.

What is the operating temperature range of QDD-200G-SR8?

The QDD-200G-SR8 optical module's operating temperature range is typically between 0 and 70 degrees Celsius. Within this range, the optical module can work normally and maintain stable performance.

The product was received in a very sturdy package, the first time we tested it we could not connect properly and thought we had bought a bad product, after communicating with the technician we realized that we should have used a 16-core jumper instead of a 12-core, and it is now running very well, and I have a very good impression of their service staff.
