# Product Documentation
# Product Description
100GBASE CWDM4 is Multi-Vendor MSA Compatible 100G CWDM4 (Quad Small Form-Factor Pluggable 28) Transceiver, operating over pair of single-mode optical fiber. 100GBASE CWDM4 adopts CWDM MUX/DEMUX technology with central CWDM4 wavelengths of the lanes at: 1271, 1291, 1311, 1331 nm. On the transmission side 100GBASE CWDM4 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). QSFP28 100G CWDM4 has minimum guaranteed optical budget of 3.5 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 CWDM4 uses cooled 4x28Gb/s LAN WDM TOSA (CWDM4 wavelengths 1271, 1291, 1311, 1331 nm) laser transmitters and 4x28Gb/s PIN ROSA receivers. 100G QSFP28 CWDM4 optics 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 optics/ 100G 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 (CWDM 100G) QSFP28 100G CWDM4 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.
QSFP28 CWDM4 is CE/RoHS certified and is compliant with product safety standards. 100G-QSFP28-2.1 (CWDM 100G) Transceiver is fully compliant to QSFP28 Multi Source Agreement (MSA), 100G CWDM4 MSA and 100G CLR4 Alliance, 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 CWDM4 MSA /CLR4 QSFP28 transceiver in order to make it work in almost any brand equipment.

FAQ:
What are the differences between QSFP28 4WDM vs QSFP28 CWDM4?
In summary, QSFP28 100G CWDM4 and QSFP28 4WDM have varying specifications regarding both distance and wavelengths: QSFP28 100G CWDM4 supports distances of 2km and 10km using CWDM wavelengths while QSFP28 4WDM supports distances of 20km and 40km utilizing LAN WDM wavelengths.
What are CWDM4 wavelengths?
The QSFP28 100G CWDM4 utilizes four CWDM channels with central wavelengths at 1271nm, 1291nm, 1311nm, and 1331nm, following the ITU-T G.694.2 standard.It features a duplex LC connector for optical interface and a 38-pin connector for electrical interface.
What are the differences between 100G QSFP28 CWDM4 and 100G QSFP28 CLR4?
The primary distinction lies in the Forward Error Correction (FEC) function. QSFP28 100G CWDM4 necessitates FEC support, while for 100G CLR4, FEC is optional.100G CLR4 can operate both with and without FEC.
