The 200G QSFP 56 transceiver module uses mainstream digital signal processors (DSP) to achieve more efficient optical interconnection with flexible expansion scale and low cost. It is an optical transceiver specially designed for 200G Ethernet interconnection.
The 200G QSFP 56 package transceiver module adopts PAM4 modulation technology, which overcomes the weak ability of traditional NRZ modulation at 56G rate, and can not only save optical fiber cost but also reduce link loss. Common 200G QSFP 56 transceiver module are 200G QSFP 56 SR4, DR4, FR4, LR4, ER4, etc. In this blog, Unitekfiber will introduce in detail the 200G QSFP 56 SR4 optical module of the 200G data center short-distance transmission solution.
The product features of 200G QSFP 56 SR4 transceiver module.
200G QSFP 56 SR4 is a 4 channel full-duplex transceiver module, adopting hot-swappable QSFP 56 package, the rate is up to 212.5Gbps, in line with QSFP 56 MSA and IEEE 802.3cd 200GBASE-SR4 Ethernet protocol, the center wavelength is 850nm, using MPO-12 optical port, power consumption is less than 5W.
The application of 200G QSFP 56 SR4 transceiver module.
The 200G QSFP 56 SR4 optical transceiver module adopts 50G PAM4 and VCSEL technology, and is mainly used in 200GBASE-SR4 Ethernet links in data centers. Under the premise of enabling FEC in the system, it can realize 200Gbps data interconnection within 100m through multimode fiber. The transmission distance can reach up to 70m through OM3 multimode fiber, and up to 100m through OM4 or OM5 multimode fiber.
