SFP-transceivermodule BlueOptics SFP-DGD-LX-BO 1250 Mbit/s 1310 nm zilver

The BlueOptics SFP-DGD-LX-BO is a single‑mode fiber optic SFP transceiver module designed for 1250 Mbit/s (1.25 Gbit/s) data links over long distance. It operates at a wavelength of 1310 nm, uses an LC duplex connector and is housed in a metal casing with a compact SFP form factor and a 3.3 V supply. The module supports standard 1000BASE‑LX optical interfaces and is intended as a drop‑in compatible transceiver for equipment that accepts MSA‑compliant SFP modules.

Advantages

The module provides reliable optical transmission using a 1310 nm laser and receiver pair optimized for single‑mode fiber, enabling data transfer up to 1.25 Gbit/s. Its metal housing ensures mechanical stability and heat dissipation while the small, lightweight SFP form factor simplifies installation and replacement. Built to MSA standards, the transceiver supports digital diagnostic monitoring (DDM/DOM) when host devices provide the interface, helping with remote status monitoring of voltage, laser bias, output power, received power and temperature.

Suitable for

• Long‑reach Gigabit Ethernet links (1000BASE‑LX) over single‑mode fiber
• Interconnecting switches, routers and storage systems with LC duplex interfaces
• Fiber uplinks in enterprise and campus networks
• Optical links requiring DDM/DOM monitoring support

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or optical interface module with the module’s ejector lever aligned for proper seating. Connect LC duplex single‑mode patch cords to the transmit and receive ports, ensuring correct TX/RX orientation. Verify the host device recognizes the module and, if applicable, enable or query the DDM/DOM monitoring through the device management interface to read real‑time diagnostic values. Follow the network equipment vendor’s hot‑swap and handling guidelines to avoid ESD or mechanical damage.

Recommendations

Use single‑mode LC duplex patch cords and follow recommended fiber installation practices to achieve the specified range and signal quality. Confirm host compatibility and DDM support in advance. Store unused modules in anti‑static packaging and avoid touching the optical interfaces; clean connectors before mating to prevent signal loss.
