SFP-transceiver module BlueOptics SFP992-1LH-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP992-1LH-BO is a single‑mode SFP transceiver module designed for optical data links with a maximum throughput of 1250 Mbit/s at a wavelength of 1550 nm. Housed in a metal casing and powered by a 3.3 V supply, this compact 2 g module provides an LC duplex optical interface compatible with MSA SFP form‑factor equipment. It implements transmit and receive functions on 1550 nm for long‑reach single‑mode fiber connections and supports standard 1000BASE‑EX applications over extended distances.

Advantages

The module’s metal housing offers mechanical robustness and EMI resilience while the small, standardized SFP form factor simplifies hot‑swap replacement in switches, routers and storage systems. Native support for common optical protocols at up to 1.25 Gbit/s enables interoperability with MSA‑compliant network hardware. Low weight and a 3.3 V supply requirement make the transceiver suitable for dense installations and typical SFP slots without special power considerations.

Suitable for

• Long‑reach single‑mode Ethernet links (1000BASE‑EX)
• Interconnects between switches, routers and storage systems
• Fiber backbone segments and campus network aggregation
• Environments requiring MSA‑compliant, hot‑swappable SFP modules

• Weight: 2 g

How to use

Install the BlueOptics SFP992-1LH-BO into any compatible SFP slot while the host equipment is powered on or off, observing the device’s alignment and insertion orientation. Connect single‑mode LC duplex patch cords to the transceiver’s ports, ensuring transmit-to-receive pairing with the remote module. Configure the host interface for 1000BASE‑EX or the appropriate optical link protocol; the module supports standard SFP management and may expose DDM/DOM diagnostic parameters if the host system provides support.

Recommendations

Use high‑quality single‑mode LC patch cords and verify link polarity for optimal performance. Confirm that your network hardware supports third‑party SFP modules and DDM/DOM if you require remote diagnostics. For long‑distance links, follow vendor guidelines on optical budget and attenuation to ensure reliable throughput up to the supported range.
