SFP transceiver module BlueOptics SFP-76DH-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-76DH-BO is an SFP fiber optic transceiver module designed for single-mode links. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 1550 nm. Housed in a metal casing and powered by a 3.3 V input, this compact transceiver weighs approximately 3 g and uses an LC duplex interface for simultaneous transmit and receive over separate fibers. The module follows MSA SFP form-factor conventions and is suitable for long-reach 1000BASE-ZX deployments when paired with appropriate single-mode fiber cabling.

Advantages

The module provides a stable 1.25 Gbit/s optical link at 1550 nm in a compact SFP metal housing, offering compatibility with equipment that supports 1000BASE-ZX SFP transceivers. Built to MSA standards, it supports digital diagnostics (DDM/DOM) for remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware exposes these features. High-quality optical components and tested compatibility contribute to long operational lifetime and reduced maintenance needs.

Suitable for

• Long-reach single-mode Ethernet links (1000BASE-ZX)
• Interconnecting routers, switches and storage systems over single-mode fiber
• Fiber backbone segments and point-to-point links up to long distances with appropriate fiber
• Environments requiring remote optical diagnostics and monitoring

Key specifications

• Interface type: SFP (LC duplex)
• Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
• Operating wavelength: 1550 nm
• Power supply: 3.3 V input
• Housing: metal
• Weight: approximately 3 g
• Supports digital diagnostics monitoring (DDM/DOM) per SFF-8472 when supported by host
• Designed for single-mode fiber

How to use

Insert the BlueOptics SFP-76DH-BO into an SFP port on supported network equipment ensuring correct orientation and a firm seating until the module latches. Connect LC duplex single-mode patch cords to the transmit and receive ports, observing correct fiber polarity. Power on the host device; the link status should negotiate at the appropriate speed if the connected equipment supports 1000BASE-ZX. If the host supports DDM/DOM, use its management interface to read real-time diagnostic parameters for monitoring and troubleshooting.

Recommendations

Use low-loss single-mode fiber and LC duplex connectors rated for long-reach 1550 nm transmission to achieve expected link distance and performance. Verify that the network hardware firmware or driver supports third-party SFP modules and DDM/DOM access if remote diagnostics are required. Handle the optical interfaces with dust caps when not connected and follow ESD precautions during installation.
