SFP transceiver module BlueOptics SFP-GLS-70-A-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-GLS-70-A-BO is an SFP fiber optic transceiver designed for single‑mode links with a nominal data rate of 1250 Mbit/s and an operating wavelength of 1550 nm. Housed in a metal casing and powered by a 3.3 V input, the module is compact and lightweight (approx. 3 g) and uses an LC duplex interface for simultaneous transmit and receive over separate fibers. The module is compliant with common MSA SFP form‑factor requirements and is suitable for use in switches, routers and other networking equipment that support 1000BASE‑ZX style optical interfaces.

Advantages

The transceiver provides reliable long‑reach single‑mode transmission at 1550 nm and supports up to 1250 Mbit/s throughput. Its metal housing ensures mechanical robustness and thermal stability while the compact SFP form factor allows hot‑pluggable deployment in standard SFP slots. The LC duplex optical interface enables bidirectional communication and the module is compatible with standard digital diagnostics (DDM/DOM) when supported by the host device, aiding monitoring and troubleshooting.

How to use

Insert the BlueOptics SFP‑GLS‑70‑A‑BO into a compatible SFP port on a switch, router or other network device while the host is powered according to the device instructions to avoid interruption. Connect LC duplex single‑mode patch cords to the transmit and receive ports, ensuring correct fiber polarity. If the host supports digital diagnostics (DDM/DOM), enable or query the diagnostic interface via the device management tools to monitor supply voltage, laser bias current, output power, input power and temperature. Verify link parameters and configure the device port for the appropriate protocol (for example 1000BASE‑ZX) as required by the network design.

Recommendations

Use quality single‑mode LC duplex patch cords and appropriate patch panels to achieve the specified range and signal quality. Ensure the host device firmware supports third‑party SFP modules and DDM/DOM if remote diagnostics are needed. Observe ESD precautions during handling and avoid exposure of the optical interface to dust or direct sunlight; cap unused ports when not connected.
