BlueOptics 321-1646-BO optický transceiver modul 40000 Mbit/s QSFP 850 nm

The BlueOptics 321-1646-BO is a QSFP fiber optic transceiver module for high-speed short-reach networks. It supports a maximum data transfer rate of 40,000 Mbit/s, operates at a wavelength of 850 nm and uses an MPO/MTP-style multi-fiber interface compatible with QSFP form-factor deployments. The module is lightweight (approximately 20 g), RoHS-compliant and is specified with a high mean time between failures (MTBF) to meet availability requirements in data center and enterprise environments.

Advantages

The transceiver offers multi-mode fiber support for short-range 40G links with simultaneous transmit and receive channels in the QSFP package. Designed to follow MSA standards, it is manufactured with components that enable long service life and consistent performance. Digital diagnostic monitoring capabilities provide real-time information on key parameters where supported by host hardware. The compact silver-coloured module simplifies installation in QSFP slots while minimising weight impact.

Suitable for

• 40G Ethernet connections between switches and aggregation equipment
• High-speed links in storage and server interconnects within data centers
• Short-reach multimode fiber links up to the supported distance for 850 nm optics
• Environments requiring RoHS-compliant, QSFP-format transceivers

Key specifications

• Interface type: QSFP (Quad Small Form-factor Pluggable)
• Maximum data transfer rate: 40000 Mbit/s
• Optical wavelength: 850 nm
• Connector type: MPO/MTP multi-fiber (QSFP-compatible MPO for SR4 use)
• Fiber type: multimode fiber (designed for short-reach multimode links)
• Weight: approximately 0.02 kg
• Product colour: silver
• Compliance: RoHS
• Reliability indicator: MTBF specified (high availability design)

How to use

Install the BlueOptics 321-1646-BO into a compatible QSFP port following the host device manufacturer's hot-plug and electrostatic discharge procedures. Connect the MPO/MTP patch cord to the module and route the multimode fiber to the corresponding MPO/MTP termination or patch panel. Confirm link negotiation and speed on the host system; if available, enable and read digital diagnostic monitoring through supported management interfaces to verify operating parameters. Remove the transceiver by following the reverse of the insertion procedure when performing maintenance or replacement.

Recommendations

Use short-length multimode OM3/OM4 patch cords and proper MPO/MTP polarity and keying for SR4 deployments. Verify that the target switch or other hardware explicitly supports third-party QSFP transceivers and DDM/DOM functions if diagnostic monitoring is required. Store unused modules in anti-static packaging and avoid exposure to dust or direct sunlight to maintain optical performance.
