Our 200GBASE-FR4 QSFP56 transceiver enables cost-effective 200G connectivity for data center interconnects. Supporting 2km transmission over single-mode fiber with CWDM wavelengths (1270/1290/1310/1330nm), this module delivers 4 dB link budget with PAM4 modulation at 53. 125 Gbps. Use Juniper's portfolio of 2 x 100G optical transceivers to service point-to-point 200G interconnections or breakout to interoperate with widely deployed legacy four-wavelength 100G interfaces. Designed for data center 200GBASE-SR4 Ethernet links reach up to 100m over 4 pairs of parallel MMF with FEC. Designed in compact form factors such as QSFP56 and QSFP-DD, these transceivers support 200G. GIGALIGHT provides the smart box tools for online coding of SFP, XFP, SFP+, QSFP+, and QSFP28 optics, as well as wavelength tuning for 10G tunable XFP/SFP+ optical transceivers. GIGALIGHT provides a series of BER testing tools (checker) for 10G SFP+, 25G/32GFC SFP28, 40G QSFP+, 100G QSFP28, 200G. Broadex Technologies' high performance and cost effective 200G Optical Transceiver Modules are built utilizing our innovative COB technology in a QSFP56 form factor.
