# Product Description

QSFP-100G-DR-S is Cisco Compatible 100G-DR Single Lambda PAM4 QSFP28 (Quad Small Form-Factor Pluggable 28) Transceiver, operating over pair of single-mode optical fiber. On the transmission side module converts 4x 25G NRZ (Non-return-to-zero) electrical input channels (each 25.78125Gbps) into 1 Single Lambda 100G PAM4 optical signal using PAM4 modulation with baud rate of 53.125 Gbps. Reversely the opposite is done on the receiving side, module converts 1 Single Lambda 100G PAM4 optical signal into 4x 25G NRZ (Non-return-to-zero) electrical inputs using PAM4 modulation with baud rate of 53.125 Gbps. Module has minimum guaranteed optical budget of 3 dB, which in most cases is enough to reach 500 m 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. QSFP-100G-DR-S uses EML TOSA (which operates over 1304.5- 1317.5 nm range) laser transmitters and 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. QSFP-100G-DR-S operates in Standard 0°-70°C temperature range and has double LC connectors. 100G-DR Single Lambda PAM4 QSFP28 support up to 106.25 Gbps data rate and such applications as 100G Ethernet (103.125 Gbps). QSFP-100G-DR-S 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. QSFP-100G-DR-S as a Single Lambda PAM4 module can interoperate with 400G transceivers that comply with IEEE 400GBASE-DR4, such as Cisco’s QSFP-400G-DR4-S, via fiber break-out cables.

Our version of compatible Cisco QSFP-100G-DR-S is based on our product 100G-QSFP28-SL500 which is CE/RoHS certified and is also fully compliant to QSFP28 Multi Source Agreement (MSA), IEEE802.3cd 100GBASE-DR and 100G Lambda MSA standard. To ensure compatibility we have tested our compatible version of Cisco QSFP-100G-DR-S Transceiver in latest platforms of Cisco networking equipment, which allows us to encode transceiver EEPROM memory to be compatible and work seamlessly with Cisco platforms. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP transceiver EEPROM memory data validation tests. We will be glad to know your requirements – <Contact Us.
