## Long description

The BlueOptics B235-BO 1250 Mbit/s 850 nm Silver is an SFP transceiver module engineered for short-range fiber optic links in modern networks. It supports a maximum data transfer rate of 1250 Mbit/s at a transmission wavelength of 850 nm and comes in a durable metal housing with a compact, lightweight design. The module uses a standard SFP interface and requires a 3.3 V input to operate, making it compatible with many switches and transceivers that accept hot-pluggable SFP modules.
Advantages
The module provides stable 1.25 Gbit/s-class connectivity over multimode fiber at 850 nm while maintaining a low physical footprint and a metal casing for mechanical protection and thermal dissipation. Its SFP form factor allows hot-plug installation and straightforward replacement in compatible network equipment. At approximately 20 g weight and a silver finish, the unit is easy to handle during deployment and fits standard SFP ports without modifications.
Suitable for
 Short-range multimode fiber connections within data centers and server rooms
 Upgrading or replacing SFP ports on network switches, routers, and media converters
 Applications requiring 1.25 Gbit/s links such as Gigabit Ethernet or Fibre Channel over short distances
Key specifications
 Interface type: SFP (Small Form-factor Pluggable)
 Maximum data transfer rate: 1250 Mbit/s
 Operational wavelength: 850 nm
 Housing material: metal casing for improved durability and heat dissipation
 Operating voltage: 3.3 V input
 Weight: approximately 0.02 kg
 Color: silver
How to use
Ensure the host device supports SFP transceivers and the required 3.3 V input. Power down the equipment if recommended by the manufacturer, align the BlueOptics B235-BO with the SFP slot and insert it until it clicks into place, or follow the hot-plug procedure supported by the target device. Connect the appropriate multimode fiber patch cable with matching connectors, observe link LED indicators on the host device to verify a successful connection, and perform any necessary configuration on network interfaces.
Usage recommendations
Use multimode fiber patch cables and compatible connectors rated for 850 nm transmission, keep optical connectors clean to avoid signal loss, and follow ESD precautions when handling the module. Verify compatibility with the target switch or router firmware and consult vendor documentation for any specific compatibility lists or required configuration steps.
