SFP transceiver BlueOptics SPL-34-43-GB-BX-BO 1250 Mbit/s Fiber optic

The BlueOptics SPL-34-43-GB-BX-BO is an SFP fiber optic transceiver designed for single-mode optical links. It supports a maximum data transfer rate of 1250 Mbit/s and uses an LC simplex optical interface. The module is housed in a metal casing for mechanical durability, has a low weight (approx. 2 g) and a reported mean time between failures (MTBF) of 1,000,000 hours, making it suitable for long-term deployment in networking equipment that follows MSA SFP form-factor standards.

Advantages

The transceiver supports 1000BASE-BX-U operation with separate transmit and receive wavelengths for single-fiber bidirectional links. Its metal housing provides robustness while the compact SFP form factor allows hot-pluggable installation in switches, routers and other compatible devices. Compliance with MSA SFP mechanical and electrical specifications ensures broad interoperability with hardware platforms that accept SFP modules.

Suitable for

• Single-mode fiber links using LC simplex connectors
• Gigabit Ethernet and similar 1.25 Gbit/s optical applications
• Hot-pluggable SFP slots in switches, routers and storage systems

Key specifications

• Interface type: SFP (LC simplex)
• Maximum data rate: 1250 Mbit/s (1.25 Gbit/s)
• Fiber type: single-mode fiber, bidirectional on one strand (BX-U)
• Transmitter/receiver wavelengths: separate tx/rx wavelengths for BX operation
• Housing: metal casing
• Weight: ~0.002 kg (2 g)
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Insert the BlueOptics SFP transceiver into a compatible SFP slot while the host device is powered on or per the device manufacturer's hot-plug procedures. Connect an LC simplex single-mode patch cable to the transceiver; ensure that the transmit/receive orientation matches the opposing transceiver (BX links use different wavelengths for tx and rx). Verify link establishment and data rate in the host device's interface status. If available, enable or query Digital Diagnostic Monitoring (DDM/DOM) in the host to monitor optical parameters.

Recommendations

Use quality single-mode LC simplex patch cords and verify host compatibility with 1000BASE-BX-U operation. If you plan to use digital diagnostics, confirm that the networking hardware supports DDM/DOM for real-time monitoring of voltage, temperature, laser bias and optical power.
