Product information

Description

The BlueOptics SFP-6421-BO 10000 Mbit/s is a compact fiber optic SFP transceiver module designed for high-speed single-mode optical links. Housed in metal and weighing only 3 g, it supports a maximum data transfer rate of 10000 Mbit/s and a maximum reach of up to 10000 m. The module operates at a 3.3 V input voltage and uses an SFP interface with an LC simplex-style optical connection suited for 10GBASE-BX-U applications, providing simultaneous transmit and receive channels over a single fiber when paired with appropriate counterparts and cabling.

Advantages

The module combines a small form factor and metal housing for robust physical protection with support for 10 Gbit/s data rates and long single-mode reach. Built to MSA-compatible mechanical and optical specifications, it is designed for straightforward installation in standard SFP ports and for interoperability with hardware platforms that support 10GBASE-BX-U transceivers. Low weight and standard 3.3 V operation simplify integration into switches, routers and storage systems where compact, low-power optics are required.

Suitable for

  • Long-reach single-mode Ethernet links up to 10 km
  • 10GBASE-BX-U optical uplinks for switches and routers
  • Data center and campus backbone connections
  • Fiber links between network appliances, storage systems and servers

Key specifications

  • Maximum data transfer rate: 10000 Mbit/s (10 Gbit/s)
  • Maximum transfer distance: up to 10000 m (single-mode fiber)
  • Connector type: LC simplex optical interface via SFP form factor
  • Housing: metal enclosure
  • Input voltage: 3.3 V operating supply
  • Product colour: silver
  • Weight: approximately 0.003 kg

How to use

Insert the SFP transceiver into a compatible SFP slot on the switch, router or other network device while the host is powered down or following the vendor’s hot-swap instructions. Connect a single-mode LC simplex fiber patch cable to the optical port, ensuring correct alignment with the remote transceiver and correct wavelength pairing for BX-U operation. Verify that the host device recognizes the module and that link status and speed are negotiated at 10 Gbit/s. If the host and transceiver support DDM/DOM, use the management interface to monitor supply voltage, laser bias current, received power and temperature for diagnostics.

Usage recommendations

Use high-quality single-mode LC patch cords and, where applicable, BlueOptics-certified cables or patch panels to achieve the stated reach and signal quality. Confirm compatibility with the host device firmware and enable DDM/DOM monitoring if remote diagnostics are required. Follow ESD precautions when handling the module and store it in anti-static packaging when not installed.
