200G QSFP56 Overview
The 200G QSFP56 category contains two optical transceiver modules designed for 200G Ethernet connections in data centers, high-performance computing networks, and enterprise core and aggregation layers. Both models use the QSFP56 form factor and support DOM monitoring. The series includes one multimode SR4 transceiver and one single-mode FR4 transceiver, covering transmission distances from 100m to 2km. Depending on the optical specification, the modules use either an MTP/MPO-12 UPC connector for parallel optical transmission or a duplex LC/UPC connector for longer-reach links.
Q56-200G-SR4 This 200GBASE-SR4 QSFP56 transceiver operates at 850nm over multimode fiber. Its SR4 parallel optical interface uses an MTP/MPO-12 UPC connector and supports transmission distances up to 100m. The module incorporates DOM monitoring and provides short-reach 200G Ethernet connectivity for data centers, high-performance computing networks, and enterprise core and aggregation applications.
Q56-200G-FR4 This 200GBASE-FR4 QSFP56 transceiver provides 1310nm transmission over single-mode fiber through a duplex LC/UPC connector. It supports optical links up to 2km and integrates DOM monitoring. The module is designed for longer-reach 200G Ethernet interconnections in data centers, high-performance computing networks, and enterprise core and aggregation environments.
FAQ
- What is the main deployment difference between Q56-200G-SR4 and Q56-200G-FR4?
Q56-200G-SR4 is the short-reach option, supporting up to 100m over 850nm multimode fiber with an MTP/MPO-12 UPC connector. Q56-200G-FR4 supports up to 2km over 1310nm single-mode fiber with a duplex LC/UPC connector.
- Can Q56-200G-SR4 establish a 200G Ethernet link across 100m of multimode fiber?
Up to 100m. Q56-200G-SR4 uses 850nm parallel optical transmission over multimode fiber and connects through an MTP/MPO-12 UPC interface.
- How far can Q56-200G-FR4 extend a 200G Ethernet connection over single-mode fiber?
Up to 2km. Q56-200G-FR4 operates at 1310nm over single-mode fiber and uses a duplex LC/UPC connector for the optical link.
- Why do Q56-200G-SR4 and Q56-200G-FR4 use different optical connectors?
Q56-200G-SR4 carries four parallel optical lanes over multimode fiber, requiring an MTP/MPO-12 UPC interface. Q56-200G-FR4 multiplexes four optical wavelengths over a duplex single-mode fiber pair, allowing it to use duplex LC/UPC.
- Do both models in the 200G QSFP56 category support digital optical monitoring?
Yes. Both Q56-200G-SR4 and Q56-200G-FR4 support DOM, allowing the host system to access module operating and diagnostic information through the management interface.
- Which network environments are the 200G QSFP56 optical transceivers designed for?
They are designed for 200G Ethernet interconnections in data centers, high-performance computing networks, and enterprise core and aggregation layers. Q56-200G-SR4 serves short multimode links, while Q56-200G-FR4 supports longer single-mode links.
- Do Q56-200G-SR4 and Q56-200G-FR4 require different host-side module cages?
No. Both use the QSFP56 form factor and are intended for compatible 200G Ethernet QSFP56 ports. Their main deployment differences are the optical media, connector type, wavelength, and supported link distance.
