SFP transceiver module BlueOptics SFP-4240-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-4240-BO is a single‑mode fiber optic SFP transceiver module designed for 1.25 Gbit/s (1250 Mbit/s) optical links at a wavelength of 1310 nm. The module comes in a metal housing, weighs approximately 3 g and operates from a 3.3 V supply. It uses an LC duplex optical connector and follows MSA-compliant SFP form factor for compatibility with networking equipment that supports 1000BASE‑LH style SFP transceivers. The transceiver is intended for long-reach single‑mode fiber links and supports standard optical protocols for Ethernet, Fibre Channel over Ethernet and SDH/SONET within its link budget.

Advantages

The BlueOptics SFP-4240-BO provides MSA-compliant SFP interoperability in a compact metal housing that ensures mechanical stability and EMI resistance. With a 1310 nm optical wavelength and support for up to 1250 Mbit/s, it is suitable for long-reach single‑mode fiber transmission using LC duplex connections. Low weight and a standard 3.3 V interface make it easy to install in a wide range of switches, routers and other network devices that accept SFP modules. The module also supports digital diagnostics monitoring when the host hardware implements DDM/DOM functions, enabling remote access to basic optical and electrical parameters.

Suitable for

• Long-reach single‑mode fiber links up to typical 1000BASE‑LH distances
• 1.25 Gbit/s Ethernet and related optical network protocols
• Replacement or expansion ports in SFP-compatible switches, routers and storage interfaces
• Environments requiring compact, metal‑housed SFP transceivers

How to use

Insert the BlueOptics SFP-4240-BO into an empty SFP slot on a compatible switch, router or other network device while the host device is powered down or following the vendor's hot‑swap instructions. Connect LC duplex single‑mode fiber patch cords to the module's transmitter and receiver ports, observing correct Tx/Rx orientation. Ensure the host device supports the required data rate and optical wavelength and, if diagnostic monitoring is needed, that the device supports DDM/DOM access. After installation, verify link status and data transmission using the host device's management interface.

Usage recommendations

Use quality single‑mode LC duplex patch cords and, where possible, patch panels to maintain optimal link loss and reach. Confirm compatibility with the target hardware by checking vendor documentation for supported SFP modules and enable digital diagnostics on the host if monitoring of optical parameters is required.
