## Summary description

The BlueOptics S-85DLC05D is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s and operates at 850 nm. It is designed for reliable data transmission in networking applications. The module is lightweight at 20 g and comes in a silver color, making it suitable for various setups. It is sold individually and is ideal for enhancing network performance.

## Long description

The BlueOptics S-85DLC05D 1250 Mbit/s 850 nm is a compact SFP fiber optic transceiver module designed for single-channel serial data links. Supporting a maximum data rate of 1250 Mbit/s and operating at an 850 nm wavelength, this module is intended for short-range multimode fiber connections in networking equipment that accepts SFP form-factor modules. The transceiver is lightweight (0.02 kg) and finished in silver, supplied as a single unit for integration into switches, routers or media converters that require hot-pluggable optical interfaces.
Advantages
The module delivers stable, standards-compatible optical transmission at 850 nm for multimode fiber environments while occupying a small SFP slot. Its 1250 Mbit/s capability makes it suitable for Gigabit Ethernet and similar serial protocols. The metalized silver housing provides physical protection and thermal dissipation without adding significant weight. Being an SFP transceiver, it supports hot-swapping for minimal service disruption during maintenance.
Suitable for
 Short-range multimode fiber links in data center racks and wiring closets
 Gigabit Ethernet uplinks and cross-connects
 Integration into compatible switches, routers and media converters with SFP ports
 Replacing or expanding optical ports in enterprise and SMB networks
Key specifications
 Form factor: Small Form-factor Pluggable (SFP)
 Wavelength: 850 nm (multimode fiber)
 Maximum data transfer rate: 1250 Mbit/s
 Typical use: Short-range optical links (multimode)
 Weight: 0.02 kg
 Color: Silver
How to use
Install the transceiver into an empty SFP port on compatible networking equipment until it clicks into place. Connect the multimode fiber patch cable with matching connectors to the optical interface, observing correct polarity. After insertion, the host device should detect the module and negotiate the link at the supported data rate; follow the device's management interface to confirm link status and diagnostics. For removal, power down or follow the host’s recommended hot-swap procedure and gently pull the module from the SFP slot using the release mechanism.
Usage recommendations
Use multimode fiber and supporting patch cords designed for 850 nm transmission and ensure connector types match the host equipment. Keep protective dust caps on the transceiver and cable connectors when not in use to avoid contamination. Operate the module within the host equipment’s specified temperature range and handle the unit carefully to prevent electrostatic discharge or mechanical damage.
