100G QSFP28 Transceivers

Welcome to our collection of 100G QSFP28 transceivers! The 100G QSFP28 optical transceiver are designed according to SFF-8665 standard which specifies QSFP+ 28 Gb/s 4X Pluggable Transceiver Solution (QSFP28) for 100 Gigabit Ethernet. 100G QSFP28 transceivers have the exact same footprint as it’s predecessor 40G QSFP+, but has variations where modules can have NRZ modulation (100G SR4, LR4, ER4, ZR4…) and there are some newer generation 100G QSFP28 Single Lambda modules (100G LR1, FR1, DR1) which use PAM4 modulation (more on PAM4 vs NRZ). We offer a wide range of optical modules tailored to diverse networking environments to cover all industry needs. Some of our most popular 100G modules are the 100G QSFP28 SR4 (PN: 100G-QSFP28-100) designed for short range (below 150m) Multi-Mode Fiber connections, 100G QSFP28 LR4 (PN: 100G-QSFP28-10) designed for long range (up to 10km) Single-Mode Fiber connections and 100G QSFP28 ER4 (PN:100G-QSFP28-40) designed for long range (up to 40km) Single-Mode Fiber connections. To help engineers find the correct units for their setup, we’ve sorted our 100G QSFP28 transceivers in the categories below based on their type and functionality. Not only do we offer a wide range of MSA compatible modules, but all of them can be re-programmed to be compatible with a wide range of devices. From industry-standard solutions to specialized modules, find the perfect fit for your network requirements.
