Cisco compatible MA-QSFP-40G-LR4 Description

MA-QSFP-40G-LR4 is Cisco Meraki Compatible QSFP (Quad Small Form-factor Pluggable) Transceiver, operating over pair of singlemode optical fiber providing four independent optical communication lanes seperated from each other using WDM technology. Module has minimum guaranteed optical budget of 9.7 dB, which in most cases is enough to reach 10 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. MA-QSFP-40G-LR4 uses 4 x DFB transmitting lasers and 4 x PIN receivers, operating each lane with speeds of 11.2 Gbps, giving an aggregated maximum bandwidth of 44.8 Gbps. Module supports DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. MA-QSFP-40G-LR4 Cisco Meraki compatible operates in Standard 0°-70°C temperature range and has double LC connector. MA-QSFP-40G-LR4 support 39.81 - 44.8 Gbps data rate and such applications as 40G Ethernet (41.25 Gbps). MA-QSFP-40G-LR4 optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are Internet Service Provider (ISP) Fiber To The Home aggregation and backbone, Mobile operator core and back-haul 40G applications, Data Center networking site interconnections and other optical links.

Cisco Meraki compatible MA-QSFP-40G-LR4 is CE/RoHS certified and meets product safety requirements. We run compatibility tests on the Cisco Meraki compatible MA-QSFP-40G-LR4 QSFP+ Transceiver using the newest Cisco Meraki networking platforms, allowing us to encode the transceiver's EEPROM memory to be compatible and work seamlessly with Cisco Meraki systems. Our optical transceivers, on the other hand, comply with the QSFP+ Multi Source Agreement and the SFF-8636 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 QSFP transceivers. Please contact us so that we can learn more about your requirements.
