Product information

Description

MicroOptics MO-G-S31121-3CL10 is an SFP fiber optic transceiver module designed for single-port small-form-factor pluggable applications. The module supports a data rate up to 1250 Mbit/s over fiber and conforms to industry MSA compatibility for straightforward interoperability with a wide range of switches, routers and telecommunications equipment. Its compact dimensions (13.4 × 56.5 × 8.5 mm) allow high-density deployment in chassis-based and standalone networking devices where space is limited.

Advantages

The transceiver offers a compact SFP form factor that enables easy hot-plug installation and replacement without interrupting system operation. Compliance with MSA mechanical and electrical specifications ensures predictable performance and interoperability across vendors. With support for up to 1250 Mbit/s throughput, the module fits common gigabit and legacy fiber links while minimizing power and board-space requirements. The small size and standardized interface simplify inventory and maintenance for network operators.

Suitable for

Fiber uplinks between switches and routers in enterprise and carrier networks
Small-form-factor installations in data centers and server cabinets
Telecommunications and access network equipment requiring pluggable fiber modules
Equipment refresh or expansion where MSA-compliant SFP modules are required

Key specifications

Form factor: SFP (small-form-factor pluggable)
Maximum data rate: 1250 Mbit/s
Connector type: fiber optic interface (SFP optical port)
Physical dimensions: 13.4 × 56.5 × 8.5 mm
Standards: MSA-compliant mechanical and electrical compatibility

How to use

Install the transceiver into an available SFP slot on a compatible switch, router, or media converter by inserting the module until it clicks into place. Connect the appropriate fiber patch cable to the optical port, observing correct fiber type and polarity for the link. Configure the host device port settings (speed, duplex, and any required link parameters) according to network design. For safe removal, disable or shut down the port if required by the equipment manufacturer, then press the module latch and gently pull the transceiver out.

Usage recommendations

Use this SFP transceiver with compatible single-mode or multimode fiber and patch cords as specified by your network equipment vendor. Store and handle the module in a clean, static-free environment, protect the optical interface with dust caps when unused, and follow manufacturer guidelines for operating temperature and power budget to ensure reliable link performance.
