Cisco compatible MA-QSFP-40G-CSR4 Description

MA-QSFP-40G-CSR4 is Cisco Meraki Compatible QSFP (Quad Small Form-factor Pluggable) Transceiver, operating over four parallel pairs of multimode optical fiber providing four independent optical communication lanes. It has minimum guaranteed optical budget of 2.5 dB, which in most cases is enough to reach 400 distance using OM4 type multi-mode cable or 300m distance using OM3 type 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-CSR4 transceiver use top quality 4 x VCSEL transmitters which operate at nominal wavelength 850 nm and 4 x 850 nm PIN photodiode receivers. Module supports DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. MA-QSFP-40G-CSR4 operates in Standard 0°-70°C temperature range and has MPO 12 connector. MA-QSFP-40G-CSR4 support 39.81 - 44.8 Gbps data rate and such applications as 40G Ethernet (41.25 Gbps), STM256 (39.81 Gbps), OTU3 (43.108 Gbps) and OTU3e2 (44.58 Gbps). MA-QSFP-40G-CSR4 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 compatible MA-QSFP-40G-CSR4 is CE/RoHS certified and meets product safety requirements. We run compatibility tests on the Cisco compatible MA-QSFP-40G-CSR4 QSFP 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. MA-QSFP-40G-CSR4 optical transceivers, on the other hand, comply with the QSFP Multi Source Agreement and the SFF-8436 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 MA-QSFP-40G-CSR4 QSFP transceivers. Please contact us so that we can learn more about your requirements.
