Q1: What does the "FR4" stand for in H3C QSFP56-200G-FR4?A1: "FR" designates a medium-reach standard defined by the IEEE (up to 2km over single-mode fiber), and "4" indicates that the module multiplexes data across 4 distinct optical wavelengths over a single pair of fibers using CWDM technology.
Q2: Can I plug this QSFP56 200G module into a standard 100G QSFP28 port?A2: No. the 100G QSFP28 port does not support the 200G module. their pulse modulation mode is different, 100G is for NRZ, 200G is for PAM4.and their data rate mismatch.
Q3:What is the maximum distance this 200G FR4 transceiver supports?A3: It transmit data up to 2 kilometers (1.24 miles) with standard G.652 single-mode fiber cables.
Q4: Does this module require FEC (Forward Error Correction) on the host switch?A4: Yes. The 200GBASE-FR4 module relies heavily on host-driven FEC (typically RS-FEC). for correcting random transmission errors caused by noise margins inherent to high-frequency PAM4 signaling.the FEC ensure stable transmission.
Q5: What type of optical fiber patch cords does this 200G module use? A5: The H3C 200G FR4 module uses a single-mode fiber (SMF) with Duplex LC connectors. Standard yellow G.652 single-mode cabling is recommended to achieve the full 2 km rated distance.
Q6: What is the difference between 200G SR4 and 200G FR4?A6: 200G SR4 transmit data up to 100m,using 850nm wavelength over multi-mode fiber (MMF) via an MPO-12 connector. and 200G FR4 relies on single-mode fiber (SMF) via LC duplex connectors,spanning lengths up to 2km via 1310nm band CWDM.
