200G QSFP56 LR4 is designed for use in 200 Gigabit Ethernet links on up to 10km of single mode fiber, and compliant with the QSFP MSA and IEEE 802.3bs.

200G QSFP56 LR4 Product Overview

The module is designed to support 200G Ethernet, suitable for data center and 5G backhaul links up to 10km over single mode fiber with FEC. 200G QSFP56 LR4 module is compatible with IEEE 802.3bs 200GBASE-LR4 and operate at four LWDM (short for LAN-WDM) wavelengths of 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm. With a built-in 200G PAM4 DSP, the module supports four electrical interface lanes which operate in 50G PAM4 encoding mode resulting in 200G (4x50G) data rate. The transceiver is RoHS 2.0 compliant and lead-free per Directive.

Currently, there are two main types of 200G optical modules: 200G QSFP56 and 200G QSFP-DD. First, as an evolution of the 40G QSFP+ and 100G QSFP28, the QSFP56 (Quad 50 Gigabits Small Form-factor Pluggable) is designed specifically for 200G Ethernet. QSFP56 denotes 4 x 50 to 56Gb/s in a QSFP form factor. Compared with QSFP+ and QSFP28, the QSFP56 form factor as a 200G QSFP supporting 4 x 50G channels can achieve higher network speeds. The most important change from QSFP+ and QSFP28 to QSFP56 is that QSFP56 changes from NRZ encoding to PAM4 encoding. QSFP56 optical modules are available in two main package forms: QSFP56 SR4 and QSFP56 FR4
