Cisco compatible QSFP-100G-4W40-I Description

The QSFP-100G-4W40-I is a Cisco compatible 100GBASE-ER4 Lite QSFP28 (Quad Small Form-Factor Pluggable 28) Transceiver that operates across four independent optical communication lanes separated by LAN WDM technology. With a minimum guaranteed optical budget of 20 dB (with host FEC) and 16 dB (without host FEC), the module may reach distances of 40 km (with host FEC) and 30 km (without host FEC) utilizing single-mode cable. Distance, on the other hand, is merely an informative metric determined for ease of identification. Finally, we calculate distance using a minimum optical budget and industry average attenuation of optical cabling. Cisco Compatible QSFP-100G-4W40-I uses EML cooled 4x25Gb/s LAN WDM TOSA (1295.56, 1300.05, 1304.58, 1309.14nm) laser transmitters and 4 x 25 Gb/s APD ROSA receivers. DDM/DOM optical diagnostics are supported by this module, which offer diagnostic information regarding the current operating conditions. Furthermore, the module provides the FEC (Forward Error Correction) feature, which aids the receiving side in detecting and correcting bit mistakes and improving the link's overall quality. The QSFP-100G-4W40-I compatible runs in the industrial temperature range of -40° to 85°C and features two LC connectors. Cisco compatible QSFP-100G-4W40-I supports 100G Ethernet (103.125Gbps) application. In today's networking world, the QSFP-100G-4W40-I compatible optical transceiver is a multi-purpose module used in a variety of places. Internet Service Provider (ISP) Fiber to the Home Aggregation and Backbone, Mobile Operator Core Networks and Mobile Backhaul, and Data Center networking site interconnections are the most popular uses.

Cisco compatible QSFP-100G-4W40-I is CE/RoHS certified and meets product safety requirements. We run compatibility tests on the Cisco compatible QSFP-100G-4W40-I QSFP28 Transceiver using the newest Cisco networking platforms, allowing us to encode the transceiver's EEPROM memory to be compatible and work seamlessly with Cisco systems. Our optical transceivers, on the other hand, comply with the QSFP28 Multi Source Agreement and the IEEE 802.3ba industry standard. Because our priority is to provide excellent service, we do thorough quality inspections on all of our products before to delivery. As a result, we perform optical parameter measurements, connector cleanness testing, and EEPROM memory data validation tests on SFP+ transceivers. Please contact us so that we can learn more about your requirements.
