Cisco Compatible QSFP-40G-SR-BD Datasheet

Cisco Compatible QSFP-40G-SR-BD QSFP 40GBASE-SR-BiDi Module is based on our product BIDI-40G-QSFP-150. When You will order it will be encoded with Cisco code and it will be labeled with part number: BIDI-40G-QSFP-150-CI, where CI means Cisco Compatible. Above You can download datasheet of our BIDI-40G-QSFP-150 product.

# Product Description

   Cisco compatible QSFP-40G-SR-BD is QSFP (Quad Small Form-factor Pluggable) Transceiver is operating over Multi-Mode Fiber (MMF) optical cable. Our Cisco compatible QSFP-40G-SR-BD product datasheet and compatibility is based on BIDI-40G-QSFP-150 product. It has a minimum guaranteed optical budget of 2 dB, with in most cases is enough to reach about 150m 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 industry. This transceiver use top quality VSCEL Laser transmitter with operating at nominal wavelength Ch1:850nm; Ch2:900nm and Ch1:900nm; Ch2:850nm PIN photodiode receiver. It support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. Cisco compatible QSFP-40G-SR-BD QSFP (Quad Small Form-factor Pluggable) operates in Standard 0°-70°C temperature range and has Double LC interface. QSFP 40GBASE-SR-BiDi 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). Cisco QSFP-40G-SR-BD compatible QSFP 40GBASE-SR-BiDi 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. Our product EEPROM memory will be coded with necessary information to fully meet Cisco compatibility and will work seamlessly with platforms which support Cisco products. However, our optical transceivers are compliant to QSFP 40GBASE-SR-BiDi MSA industry standard 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 transceiver EEPROM memory data validation tests. If You have any other questions about QSFP-40G-SR-BD product datasheet and compatibility, please do not hesitate to contact Us!

What is Cisco QSFP-40G-SR-BD distance?

The QSFP-40G-SR-BD transceiver can reach 100 meters over OM3 or up to 150 meters via OM4.

What are main Cisco QSFP-40G-SR-BD specs?

40GBASE-SR-BiDi, Duplex MMF module. It supports link lengths of 100 and 150 meters on laser-optimized OM3, and OM4/OM5 multimode fibers. Ch1:850nm; Ch2:900nm.

What is the difference between Cisco QSFP-40G-SR-BD vs QSFP-40G-SR4?

The main difference is thate the SR4 module has an MTP interface, while the BD module has an LC interface; QSFP-40G-SR4 has the capability of 4x10G connectivity, while QSFP-40G-SR-BD transceivers can’t be split into 4x10G.
