## Long description

The BlueOptics QSFP-40G-CSR-S-BO is a compact QSFP transceiver module engineered for high-speed multimode fiber links. It supports a maximum data transfer rate of 40 Mbit/s and operates at an 850 nm wavelength using an MPO/MTP fiber connector. With a lightweight design (0.04 kg) and an MTBF of 1,000,000 hours, this 40 Gigabit Ethernet compatible transceiver is intended for use in network equipment that accepts QSFP modules and MSA-compliant interfaces.
Advantages
The module provides an industry-standard QSFP form factor with MPO/MTP connectivity for parallel multimode fiber links and operates at 850 nm for short- to medium-range optical transmission. It is produced according to MSA conventions and is described as compatible with major hardware platforms that support the original QSFP-40G form factor. The specified MTBF of 1,000,000 hours indicates a design focused on long-term availability and reduced maintenance cycles. Its small size and low weight simplify installation in dense networking environments.
Suitable for
40 Gigabit Ethernet links over multimode fiber
Interconnection of switches, routers and storage equipment that accept QSFP modules
Data center aggregation and spine-leaf topologies
Short- to medium-range optical links where 850 nm operation is used
Key specifications
Maximum data transfer rate: 40 Mbit/s
Optical wavelength: 850 nm
Interface type: 40 Gigabit Ethernet (QSFP)
Fiber connector type: MTP/MPO
Weight: 0.04 kg
Mean time between failures (MTBF): 1,000,000 hours
How to use
Install the transceiver into a compatible QSFP slot on network hardware that supports QSFP-40G modules and MSA-compliant devices. Connect the MPO/MTP multimode fiber patch cord to the transceiver and to the corresponding link endpoint or patch panel. Ensure that the connected equipment is configured for 40 Gigabit Ethernet operation and that the fiber type and link distance are appropriate for 850 nm multimode transmission. If the host hardware supports diagnostic monitoring, enable DDM/DOM to observe operational parameters where available.
Usage recommendations
Use high-quality MPO/MTP multimode patch cords and verify connector cleanliness before insertion. Confirm compatibility with the host device's QSFP interface and software requirements. For reliable operation, match the transceiver to appropriate multimode fiber (OM3/OM4 or as specified by the system) and keep fiber runs within recommended distances for 850 nm transmission.
