Juniper compatible QFX-QSFP-40G-SR4 Description

Juniper-compatible QFX-QSFP-40G-SR4 (740-067442) is QSFP (Quad Small Form-factor Pluggable) breakout transceiver, operating over 4 Lanes of MMF optical cable. Juniper-compatible QFX-QSFP-40G-SR4 transceiver price and datasheet is based on our 40G-QSFP-150 product. It has a minimum guaranteed optical budget of 1.9 dB, with in most cases is enough to reach about 150 m distance. However, distance is just an indicative parameter calculated for comfort of identification. Eventually, we calculate distance taking in account the minimal optical budget and average attenuation of optical cabling in the industry. Juniper QSFP 40G SR4 compatible transceiver use top quality VSCEL Laser transmitter operating at nominal wavelength 850 nm. and 850 nm. PIN photodiode receiver. It support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Juniper compatible QSFP 40G SR4 QSFP (Quad Small Form-factor Pluggable) operates in Standard 0°-70°C temperature range and has MTP/MPO interface. QSFP support 1.25-44.8 Gbps data rate and such applications as 4 x InfiniBand QDR(10Gbps), 40G Ethernet (41.25Gbps), OTU3 (43.01Gbps), OTU3e2 (44.58Gbps). Juniper QSFP 40G SR4 compatible QSFP optical transceiver is multi-purpose module used in a 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 backhaul 40G applications, Data Center networking site interconnections and other optical links. For more information, you can check out our juniper QFX-QSFP-40G-SR4 datasheet.

QFX-QSFP-40G-SR4 (740-067442) Juniper compatible Transceiver price & datasheet is based on our 40G-QSFP-150 product, which is fully compliant with QSFP+ Multi-Source Agreement (MSA) SFF-8436 standard, product safety standards and is CE/RoHS certified. We perform compatibility tests for Juniper-compatible Transceivers with the most recent Juniper networking equipment platforms, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly with Juniper platforms! 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 our products.
