Selection Guide: 100G QSFP28 ZR4 Transceiver

100G-QSFP28-80 transceiver module is Multi-Vendor MSA Compatible 100GBASE-ZR4 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 27 dB (with host FEC), which in most cases is enough to reach 80km distance (with host FEC) and 40km 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-QSFP28-80 uses EML cooled 4x25Gb/s LAN WDM TOSA (1295.56, 1300.05, 1304.58, 1309.14nm) laser transmitters and 4x25Gb/s SOA+PIN receivers. Module support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Additionally module supports KR4 FEC (Forward Error Correction) function which will help receiving side detect and correct bit errors and improve the overall quality of the link. 100G-QSFP28-80 operates in Standard 0°-70°C temperature range and has double LC connectors. 100GBASE-ZR4 QSFP28 support up to 103.125 Gbps data rate and such applications as 100G Ethernet (103.125 Gbps). 100G-QSFP28-80 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.

The 100GBASE-ER4 QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 40km over single mode fiber (SMF) using a wavelength of 1310nm via duplex LC connectors. Taking BOX+FPC+PCBA separate design, it has great reliability, airtightness and heat dissipation performance. This transceiver is compliant with IEEE 802.3ba 100GBASE-ER4 Lite standard. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP28 MSA, to allow access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as 100G telecom connections, data centers, high-performance computing networks,enterprise core and distribution layer applications.

Transceiver is CE/RoHS certified and it is Compliant with product safety standards. 100G-QSFP28-80 Transceiver is fully compliant to QSFP28 Multi Source Agreement (MSA) and IEEE 802.3ba 100GBASE-ZR4. 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-ZR4 QSFP28 transceiver in order to make it work in almost any brand equipment. We will be glad to know your requirements.
