# Product Documentation
Multi-Vendor MSA Compatible 40G-QSFP-10 QSFP Datasheet
Cisco Compatible QSFP-40GE-LR4 QSFP Module is based on our product 40G-QSFP-10. When You will order it will be encoded to be compatible with Cisco equipment and it will be labeled with part number: 40G-QSFP-10-CI, where CI means Cisco Compatible. Above You can download datasheet of our 40G-QSFP-10 product.
# Product Description
QSFP-40GE-LR4 is Cisco 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. QSFP-40GE-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. QSFP-40GE-LR4 operates in Standard 0°-70°C temperature range and has double LC connector. QSFP-40GE-LR4 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). QSFP-40GE-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.
Transceiver is CE/RoHS certified and it is Compliant with product safety standards. We perform compatibility tests for Cisco compatible QSFP-40GE-LR4 QSFP+ Transceiver with latest platforms of Cisco networking equipment, which allows us to encode transceiver EEPROM memory to be compatible and work seamlessly with Cisco platforms. However, our optical transceivers are compliant compliant to QSFP Multi Source Agreement SFF-8436. as well. 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 QSFP transceiver EEPROM memory data validation tests.
