Huawei compatible QSFP-40G-ER4 Description

Huawei QSFP-40G-ER4 (02311BKT) compatible is QSFP (Quad Small Form-factor Pluggable) Transceiver, operating over Double Fiber Single-Mode Fiber (SMF.) optical cable. It has minimum guaranteed optical budget of 16.3 dB, with in most cases is enough to reach about 40km 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. QSFP-40G-ER4 (02311BKT) compatible transceiver use top quality DFB Laser transmitter operating at nominal wavelength 1310 nm. and 1310 nm. APD Photodiode receiver. It support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Huawei compatible QSFP (Quad Small Form-factor Pluggable) Module operates in Standard 0°-70°C temperature range and has Double LC interface. QSFP ER4 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). This compatible QSFP ER4 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.
