Optical module model equipped with OLT

GPON OLT optical modules, including SFP and OLT Stick models, enable flexible, high-performance fiber access network deployment.Overview of OLT Optical ModulesOptical modules designed for OLTs are typically SFP (Small Form-factor Pluggable) or SFP+ modules that integrate the functionality of an OLT into a compact form factor. These modules are used in FTTH (Fiber-to-the-Home) networks and small-scale or distributed fiber deployments, allowing OLT functionality without the need for traditional large chassis-based OLTs .Key Models and FeaturesGPON OLT SFP C+++ ModulesEncapsulation type: SFP, compatible with most OLT devices such as BDCOM, HIOSO, VSOL, THINK, and TP-LINK .Transmission rates: 1.25G/2.5G, suitable for high-bandwidth applications.Optical power: High output (>7 dBm) for reliable signal over distances up to 20 km.Diagnostics: Supports DDM (Digital Diagnostic Monitoring) for monitoring optical power and temperature .GPON OLT Stick / SFP GPON OLT StickCompact SFP-form-factor module that condenses full OLT functionality into a single module .Deployment: Plugs directly into SFP ports of switches, eliminating the need for dedicated racks.Efficiency: Reduces power consumption from 15–20W to under 3W per port and cuts deployment time significantly.Compatibility: Works with 1G/2.5G/10G SFP+ interface switches, supporting incremental deployment and hot-swappable replacement .Micro OLT ModulesDesigned for edge, enterprise, or distributed environments .Capacity: Supports up to 128 ONUs, 1024 T-CONTs, and 4096 GEM ports with distances up to 60 km.Interfaces: Flexible uplink operation in HSGMII, SGMII, or GBIC modes.Monitoring: Includes optical power, voltage, and temperature monitoring, along with OMCI and SDU support .Advantages of Using OLT Optical ModulesSpace-saving: SFP-based OLT modules occupy minimal space compared to traditional rack-mounted OLTs.Energy efficiency: Significantly lower power consumption per port.Rapid deployment: Plug-and-play design reduces installation and configuration time.Scalability: Supports incremental deployment, allowing network expansion without full-card purchases.Compatibility: Works with a wide range of OLT devices and network switches, ensuring flexible integration .ConclusionFor modern fiber access networks, GPON OLT optical modules such as SFP C+++, Micro OLTs, and OLT Stick modules provide a compact, energy-efficient, and scalable solution. They are ideal for both small-scale FTTH deployments and larger distributed networks, offering high compatibility, monitoring capabilities, and simplified deployment compared to traditional chassis-based OLTs .
