100G-QSFP28-40 is Multi-Vendor MSA Compatible 100GBASE-ER4 Lite QSFP28 (Quad Small Form-Factor Pluggable 28) Transceiver, operating over pair of single-mode optical fiber with four independent optical communication lanes, separated from each other using LAN WDM technology. Module has minimum guaranteed optical budget of 20 dB (with host FEC) and 16dB (without host FEC), which in most cases is enough to reach 40km distance (with host FEC) and 30km distance (without host FEC) using single-mode cable. However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. 100G-QSFP28-40 uses EML cooled 4x25Gb/s LAN WDM TOSA (1295.56, 1300.05, 1304.58, 1309.14nm) laser transmitters and 4x25Gb/s APD ROSA receivers. Module support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Additionally module supports FEC (Forward Error Correction) function which will help receiving side detect and correct bit errors and improve the overall quality of the link. 100G-QSFP28-40 operates in Standard 0°-70°C temperature range and has double LC connectors. 100GBASE-ER4 Lite QSFP28 support up to 103.125-112.2 Gbps data rate and such applications as 100G Ethernet (103.125Gbps), Optical Transport Network OTU4 4l1-9D1F (112 Gbps) and 128G Fiber Channel (112.2 Gbps). 100G-QSFP28-40 optical transceiver is multi-purpose module used in number of different places in today’s networking environment. Most popular applications are Internet Service Provider (ISP) Fiber to the Home Aggregation and Backbone, Mobile Operator Core Networks and Mobile Backhaul and Data Center networking site interconnections.
Transceiver is CE/RoHS certified and it is Compliant with product safety standards. 100G-QSFP28-40 Transceiver is fully compliant to QSFP28 Multi Source Agreement (MSA), IEEE 802.3ba 100GBASE-ER4 Lite and IEEE 802.3bm, Optical Transport Network OTU4 4l1-9D1F and 128G Generation 6 Fiber Channel standards. Consequently compliance to above standards guarantees that module is compatible and works with majority of networking equipment, where is not implemented special algorithm for protection against third party modules. However – our technical team has accumulated deep expertise in custom-encoded firmware’s for 100GBASE-ER4 Lite QSFP28 transceiver in order to make it work in almost any brand equipment. We will be glad to know your requirements
