    Optical module SR4 and CWDM

    The SR4 module transmits four 850nm light beams over parallel multimode fiber. CWDM4 and LR4 multiplex four different wavelengths onto a single duplex LC fiber. ER4 and ZR4 achieve extended reach by utilizing powerful cooled lasers. Continuing our discussion on 100G optical modules, let's explore the essential 100G transmission standards—SR4, DR1, DR4, BiDi SR, LR4, CWDM4, SWDM4, ER, and ZR. This guide provides a comprehensive breakdown of 100G QSFP28 transceiver types, highlighting their key technical. The cost of 340 QSFP28 LR4 modules was $520 each, totaling $176,800 for a three-data-center interconnect project. 78125 Gbps (100GbE. Short answer: choose SR4 for short-reach MMF inside the data hall, CWDM4 for economical 2 km SMF, PSM4 when you already have 8-fiber SMF trunks, LR4 for 10 km metro/ campus, and ER4 for 40 km backbone. Validate connector type and fiber count before ordering. Compared to earlier form factors such as SFP+, XFP, or even QSFP+, the QSFP28 delivers four times the bandwidth—100 Gbps—within.
