SFP transceiver BlueOptics SFP-3H-BO 155 Mbit/s 1310 nm Silver

The BlueOptics SFP-3H-BO 155 Mbit/s 1310 nm Silver is a single‑port SFP fiber optic transceiver module designed for single‑mode fiber links. It supports a maximum data rate of 155 Mbit/s at a nominal wavelength of 1310 nm, is powered by a 3.3 V supply and is housed in a compact metal enclosure that weighs approximately 3 g. The module uses an LC duplex optical interface and follows MSA-compatible form factor and signal specifications for reliable integration in network equipment that accepts SFP transceivers.

Advantages

This module provides compatibility with equipment that supports 100BASE-LH / 155 Mbit/s optics while maintaining a small footprint and a durable metal housing. The single‑mode 1310 nm transmitter and receiver pair enable long-reach links up to tens of kilometers when used with appropriate single‑mode fiber and connectors. The product is built to industry MSA standards and is suitable for environments where electromagnetic immunity, compact size and low power (3.3 V) operation are required.

Suitable for

• Single‑mode fiber Ethernet links (100BASE-LH/155 Mbit/s)
• Long‑reach connections between switches, routers and storage systems
• Replacement or upgrade of SFP ports in compatible networking hardware
• Environments requiring immunity to electromagnetic interference (EMI)

Key specifications

• Interface type: SFP (LC duplex)
• Maximum data transfer rate: 155 Mbit/s
• Wavelength: 1310 nm
• Operating voltage: 3.3 V
• Housing: metal enclosure, silver colour
• Weight: approx. 3 g
• Single‑mode fiber support, long‑reach operation

How to use

Install the SFP transceiver into an empty SFP port on compatible network equipment while the host device is powered according to the vendor’s instructions. Connect an appropriate LC duplex single‑mode fiber patch cable ensuring correct transmit/receive orientation. Verify link status and supported speed on the host device. If the host supports Digital Diagnostics Monitoring (DDM/DOM), enable or query the diagnostic interface to monitor supply voltage, laser bias, optical output/input power and temperature where supported by the equipment.

Recommendations

Use high-quality single‑mode LC duplex patch cords and ensure connectors and patch panels are clean to achieve the specified range and signal quality. Confirm that the target device accepts third‑party MSA‑compliant SFP modules and that the intended link budget matches 1310 nm single‑mode operation for the desired distance.
