SFP transceiver module BlueOptics SFPGEZX120D-W-BO 1250 Mbit/s 1550 nm

The BlueOptics SFPGEZX120D-W-BO is a single‑mode SFP transceiver module that supports data rates up to 1250 Mbit/s and operates at a wavelength of 1550 nm. Housed in a metal casing and weighing approximately 3 g, the module provides a compact optical interface for long‑reach links using LC duplex connectors. It is compatible with MSA‑compliant SFP slots and is intended for integration into switches, routers and other network devices that accept standard SFP transceivers.

Advantages

The module combines a 1550 nm transmitter and receiver in a compact SFP form factor, offering low weight and a durable metal housing for stable mechanical performance. Support for common optical protocols at 1250 Mbit/s enables use in Ethernet, Fibre Channel over Ethernet or SDH/SONET environments. Built to MSA standards, the transceiver is suitable for hot‑swapping and straightforward integration into existing fiber links without custom cabling.

Suitable for

• Long‑reach single‑mode fiber connections
• Gigabit optical uplinks for switches and routers
• Storage and SAN links that require SFP optical ports
• Network equipment requiring 1550 nm wavelength transceivers

How to use

Insert the SFP transceiver into an MSA‑compliant SFP slot on your network device while the device is powered down or follow your vendor's hot‑swap instructions. Connect single‑mode LC duplex fiber patch cords, ensuring transmit and receive fibers are correctly crossed between link ends. Verify link negotiation and correct data rate settings in device firmware or operating system. If available, enable digital diagnostic monitoring (DDM/DOM) in the host device to monitor optical parameters such as supply voltage, optical power and temperature.

Recommendations

Use single‑mode fiber cabling and LC duplex patch cords rated for long‑reach 1550 nm transmission. Confirm compatibility with the host device vendor for firmware support of third‑party SFP modules and enable DDM/DOM if remote diagnostics are required. Avoid exposing the transceiver to excessive dust or moisture and follow ESD precautions during handling and installation.
