Juniper compatible JNP-QSFP-40G-LX4 Description

Juniper compatible JNP-QSFP-40G-LX4 (740-056705) is QSFP (Quad Small Form-factor Pluggable) Transceiver, operating over Multi-Mode Fiber (MMF), Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 4.5 dB (SMF) / 2.5 dB (MMF), with in most cases is enough to reach about 150m, 2km distance.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. JNP-QSFP-40G-LX4 (740-056705) compatible transceiver use top quality DFB Laser transmitter operating at nominal wavelength 1310 nm. and 1310 nm. PIN photodiode receiver. It support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Juniper compatible JNP-QSFP-40G-LX4 (740-056705) QSFP (Quad Small Form-factor Pluggable) operates in Standard 0°-70°C temperature range and has Double LC interface. QSFP Universal support 39.81 – 44.8 Gbps data rate and such applications as 40G Ethernet (41.25Gbps), STM-256 (39.81 Gbps), OTU3 (43.01Gbps), OTU3e2 (44.58Gbps). Juniper JNP-QSFP-40G-LX4 (740-056705) compatible QSFP Universal 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. For more information, you can check out our JNP-QSFP-40G-LX4 datasheet.

JNP-QSFP-40G-LX4 (740-056705) Juniper compatible Transceiver is based on our 40G-QSFP-2.1 product, which is fully compliant with QSFP+ Multi Source Agreement (MSA) SFF-8436 standard, product safety standards and is CE/RoHS certified.
