100% OEM Compatible 100GBASE-ER4 and 112GBASE-OTU4 QSFP28 Dual Rate Transceiver Module for Ethernet and Data Center (SMF, 1310nm, 40km, LC, DOM) The dual rate 100G/112G ER4 QSFP28 optical transceiver module supports 100GBASE Ethernet and 4x28G OTN client interfaces with link. 100% OEM Compatible 100GBASE-ER4 and 112GBASE-OTU4 QSFP28 Dual Rate Transceiver Module for Ethernet and Data Center (SMF, 1310nm, 40km, LC, DOM) The dual rate 100G/112G ER4 QSFP28 optical transceiver module supports 100GBASE Ethernet and 4x28G OTN client interfaces with link. Pluggable Optical transceivers for 100G Ethernet and SFP28 32G FC modules. The QSFP28 transceivers are designed for high-capacity 100G Ethernet. It is a new form factor defined in SFF Committee specifications SFF-8636 and. FS 100G QSFP28 module solutions provide various high-density, low-power 100 Gigabit Ethernet connectivity options for data centre, high-performance computing networks, enterprise core&distribution layers, and service provider applications. These are widely used across short to mid-range data centre applications within the core and aggregation layers. The dX3 Quint-speed module for TestCenter architecture was developed to meet these specific needs, offering multi-rate support, high density and performance testing for this growing market. This flexibility is needed to validate the next-generation data center fabrics and service provider routers. The idea is simple: instead of a DSP (digital signal processor) inside the module – replacing it with transimpedance amplifier (TIA) and a driver chip with high linearity and EQ capability – LPO shifts signal processing into.
