Cisco compatible QSFP-4X10G-LR-S Description

Our Cisco compatible QSFP-4X10G-LR-S Compatibility Matrix & Datasheet is based on our product 40G-QSFP-11, which has the same specifications and is manufactured in accordance with the same industry standards. Our Cisco compatible module is operating independent optical communication lanes over singlemode optical fiber. It has a minimum guaranteed optical budget of 7 dB, which in most cases is enough to reach 10 km distance using single-mode cable. However, distance is only an indicative parameter calculated for identification comfort. Finally, we calculate distance while keeping in mind the minimum optical budget and the average attenuation of optical cabling in industry. Our Cisco compatible module version uses a high-quality 4xDFB transmitting lasers and 4xPIN receivers, with each lane operating at 11.2 Gbps, for a total bandwidth of 44.8 Gbps. DDM/DOM optical diagnostics are supported by this module, which provides diagnostic information about the current operating conditions. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The compatible Cisco QSFP-4X10G-LR-S Compatibility Matrix module has a double MPO 12 connector and operates in the Standard 0°-70°C temperature range. For Cisco QSFP-4X10G-LR-S breakout cable please check our MPO-8LC-UPC-OS2. This QSFP module supports data rates ranging from 39.81 - 44.8 Gbps data rates and such applications as 40G Ethernet (41.25 Gbps), STM256 (39.81 Gbps), OTU3 (43.108 Gbps) and OTU3e2 (44.58 Gbps). Our Cisco compatible module is a multi-purpose module that can be used in a variety of networking applications. Consequently, most popular applications are Internet Service Provider, Fiber to The Home routing and switching equipment with QSFP-4X10G-LR-S Compatibility Matrix interfaces, Mobile Operator Core and Backhaul applications, Data Center networking for Ethernet connections and other optical fiber links. Our Cisco compatible transceiver has proven to be reliable in temperature-controlled server rooms over a long period of time. Our Cisco compatible modules do not require any maintenance while in use. The only possible maintenance requirement could occur during cable replacement, when the transceiver connector must be thoroughly cleaned of dust using special optical connector cleaning tools. Therefore, ensuring the best connection possible - leading to best performance!

Our Cisco QSFP-4X10G-LR-S Compatibility Matrix and Datasheet are based on our product 40G-QSFP-11, which is CE/RoHS certified and fulfills product safety standards. We perform compatibility tests for our compatible Cisco LR S Module with the most recent Cisco networking equipment platforms, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly with Cisco platforms. Furthermore, our optical transceivers comply with the QSFP Multi Source Agreement industry standard SFF-8636. Because we are committed to providing high-quality service, we conduct rigorous quality checks before delivering our products. As a result, we perform optical parameter measurements, connector cleanness tests, and EEPROM memory data validation tests on QSFP transceivers.
