Product Description
100G-QSFP28-2.1 is Multi-Vendor MSA Compatible 100G QSFP28 CWDM4 (Quad Small Form-Factor Pluggable 28) Transceiver, operating over pair of single-mode optical fiber. Module adopts CWDM MUX/DEMUX technology with central wavelength of the lanes at: 1271, 1291, 1311, 1331 nm. On the transmission side module converts 4 electrical input channels (each up to 28.05Gbps) into 4 lanes with optical signal and multiplexes them into a single channel of 100 Gbps optical transmission, reversely on the receiver side, module optically de-multiplexes 100 Gbps input into 4 lanes signals and converts them to 4 lanes of electrical data (each up to 28.05Gbps). Module has minimum guaranteed optical budget of 7 dB, which in most cases is enough to reach 2 km distance 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-QSFP28-2.1 uses cooled 4x28Gb/s LAN WDM TOSA (1271, 1291, 1311, 1331 nm) laser transmitters and 4x28Gb/s PIN 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-QSFP28-2.1 operates in Standard 0°-70°C temperature range and has double LC connector. 100G- CWDM4/CLR4 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-QSFP28-2.1 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), Mobile Operator and Data Center Core Networks.
