Product information

Description

The BlueOptics FCMJ-8521-3-DL-BO 100m is a fiber optic SFP transceiver module designed for short-range high-speed Ethernet links up to 100 meters. Constructed with a lightweight aluminium housing and weighing approximately 20 grams, this SFP-form-factor module fits standard SFP slots and integrates into existing network equipment that supports SFP transceivers. It delivers data transmission at gigabit class speeds over appropriate cabling and follows industry MSA form-factor compatibility for straightforward installation.

Advantages

The module offers a compact aluminium design that reduces weight and eases handling during installation. Compatibility with SFP interfaces ensures broad interoperability with switches, routers and other network devices that accept SFP modules. The transceiver supports gigabit data rates over distances up to 100 m, providing a reliable short-reach option for copper-to-optical or copper-based links where the SFP form factor is required.

Suitable for

  • Short-range gigabit Ethernet links in enterprise networks
  • Use in network switches and routers with SFP slots
  • Server and storage connectivity requiring SFP transceivers
  • Patch panel and data center patching applications up to 100 m

Key specifications

  • Interface type: SFP form factor
  • Nominal maximum link distance: up to 100 meters
  • Data rate class: gigabit Ethernet (1.25 G signalling class)
  • Housing material and colour: aluminium
  • Approximate weight: 0.02 kg

How to use

Insert the BlueOptics SFP module into an available SFP slot on a compatible switch, router or other network device following the device manufacturer’s insertion procedure. Connect appropriate twisted-pair or patch cabling and ensure the connected equipment is configured for the expected gigabit link speed and duplex settings. Verify link status and operational parameters in the host device management interface; no additional user configuration inside the module is required.

Usage recommendations

For reliable operation, use compatible SFP ports and appropriate cabling rated for gigabit Ethernet. Confirm device compatibility and, if necessary, update host firmware or software settings to enable third-party SFP modules. Avoid mechanical stress to the module and ensure adequate ventilation in densely populated chassis.
