SFP transceiver module BlueOptics SFP-4270-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-4270-BO is a single-mode SFP transceiver module designed for 1000BASE-ZX optical 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, the module is lightweight (approx. 3 g) and compatible with MSA-compliant SFP slots featuring an LC duplex connector. The transceiver integrates transmitter and receiver optics suitable for long-distance links over single-mode fiber and supports digital diagnostics when the host system provides DDM/DOM access.

Advantages

The module provides standardized SFP form-factor compatibility for straightforward hot-plug installation and interoperability with equipment that supports 1000BASE-ZX. Metal housing offers mechanical durability and thermal stability. Single-mode 1550 nm optics enable extended reach for metropolitan or long-haul connections while maintaining a 1.25 Gbit/s line rate. Built-in digital diagnostics support remote monitoring of key parameters such as supply voltage, laser bias current, transmit power, receive power and temperature when the host supports DDM/DOM.

How to use

Install the BlueOptics SFP-4270-BO into an available MSA-compliant SFP port on a switch, router or other network device while the host device is powered down or following the host vendor’s hot-plug instructions. Connect an appropriate single-mode LC duplex fiber patch cord to the module’s LC connector and ensure the corresponding remote transceiver is configured for 1550 nm, 1000BASE-ZX operation. Verify link status on the host device and, if required, enable or query the digital diagnostic interface to monitor optical and electrical parameters.

Recommendations

For best performance, use high-quality single-mode fiber and LC duplex patch cords, confirm both ends are configured for 1000BASE-ZX at 1550 nm, and ensure the host device supports the DDM/DOM feature if remote diagnostics are required. Observe ESD precautions when handling the transceiver and cap the optical connector when not in use to protect the fiber interface.
