Product information

Description

The BlueOptics BO25K859S2DIN is a QSFP fiber optic transceiver module designed for 40 Gbit/s network links. The module supports a maximum data transfer rate of 40000 Mbit/s and is supplied in a silver housing with a compact form factor and a weight of 40 g. Built to meet CE, FCC and RoHS standards and specified with a high MTBF, this transceiver is intended for use in modern high-speed switching and routing environments where reliable optical connectivity is required.

Advantages

This QSFP transceiver offers a high aggregate bandwidth suitable for 40 G Ethernet and other 40 Gbit/s optical applications. Its compact QSFP interface provides hot-pluggable convenience for easy insertion and replacement in compatible ports. The unit's compliance with CE, FCC and RoHS standards ensures regulatory conformity for installations in commercial and industrial networks, and the specified MTBF of 3,000,000 hours indicates long-term operational reliability under normal conditions.

Suitable for

  • 40 Gigabit Ethernet uplinks between switches and routers
  • High-density data center interconnects
  • Optical links in campus and enterprise network backbones
  • Network upgrades requiring QSFP-compatible ports

Key specifications

  • Interface type: QSFP form factor, hot-pluggable
  • Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
  • Housing colour: silver
  • Weight: 0.04 kg (40 g)
  • Mean time between failures (MTBF): 3,000,000 hours
  • Standards compliance: CE, FCC, RoHS

How to use

Install the BlueOptics BO25K859S2DIN into a compatible QSFP port following the host device manufacturer's hot-plug procedures. Ensure the transceiver and the corresponding fiber cabling are rated for the required signalling and distance. After insertion, verify link status and speed through the network device management interface. If removal is required, power down or follow hot-swap instructions in the host documentation to avoid network disruption.

Usage recommendations

Use factory-tested, type-compatible multimode or single-mode fiber and suitable connectors as specified by your network design. Maintain the transceiver and fiber connectors free of dust and debris, and handle the module by its housing to prevent damage to the optical interfaces. Observe ESD precautions when installing or removing the transceiver.
