Key Features of FS QSFP112-FR4-400G Compatible LINK-PP 425G QSFP112

FS QSFP112-FR4-400G Compatible LINK-PP module is a highly efficient 400G QSFP112 optical transceiver designed to optimize high-speed data transmission over single-mode fiber. It integrates advanced CWDM technology, a duplex LC interface, and real-time diagnostic capabilities into a compact physical-layer design. Operating within a commercial temperature range, this module provides reliable 2km reach with optimized power efficiency for modern networks.

FS QSFP112-FR4-400G Compatible LINK-PP 400G QSFP112 Optical Module

This module features a 4 CWDM lanes MUX/DEMUX design that combines and separates optical signals efficiently. It maintains a maximum power consumption of 10W, helping operators manage thermal loads in high-density switch chassis. The hot-pluggable QSFP112 form factor ensures seamless installation without disrupting active network operations.

QSFP112-FR4-400G: 400 Gbps Connectivity for Hyperscale Data Centers

Equipped with a 4 × 106.25 Gbps electrical interface compliant with 400GAUI-4, this module delivers massive throughput for cloud and hyperscale environments. It enables rapid data processing across core network backbones by utilizing 100G PAM4 signaling per lane. This rapid serialization supports intense data center traffic Demands while keeping cabling requirements minimal.

QSFP112-FR4-400G Module with CWDM Technology for Fiber Efficiency

By utilizing Coarse Wavelength Division Multiplexing (CWDM), the transceiver combines four distinct channels onto a single fiber pair. This layout maximizes the data capacity of existing single-mode fiber infrastructure without requiring costly new cable deployment. It represents a practical approach to scaling bandwidth while optimizing overall physical plant assets.

QSFP112-FR4-400G Module with 1271nm, 1291nm, 1311nm, 1331nm Wavelength

The transceiver operates across four precise grid wavelengths: 1271nm, 1291nm, 1311nm, and 1331nm. Each lane carries a 100G optical signal simultaneously with excellent channel isolation and minimal optical crosstalk. This specific wavelength spacing ensures clean signal integrity over the single-mode fiber.

QSFP112-FR4-400G Module Supporting 2km Transmission

Adhering to the 100G Lambda MSA 400G-FR4 specification, the module reliably covers spans up to 2km over standard single-mode fiber (SMF). This link budget is ideal for local intra-data center connections and campus network aggregations. It provides the necessary reach to span across large building complexes without requiring intermediate inline amplification.

QSFP112-FR4-400G Module with Duplex LC Interface

The industry-standard duplex LC optical connector interface provides a familiar, low-insertion-loss connection point for fiber patching. Its robust mechanical locking latch prevents accidental disconnections and ensures stable optical alignment. This standard connection style simplifies field deployment and matches standard enterprise patch panels.

QSFP112-FR4-400G Module with DDM for Real-Time Monitoring

Integrated Digital Diagnostic Monitoring (DDM) delivers continuous, real-time telemetry on critical operating metrics. Network administrators can remotely track parameters such as transceiver temperature, laser bias current, transmitted optical power, and received optical power. This proactive visibility allows teams to catch link degradation issues before an actual network outage occurs.

We evaluated this 400G QSFP112 FR4 transceiver for our data center spine-leaf upgrade over 1.5km OS2 single-mode fiber. The module utilizes 4 x 100G PAM4 modulation centered around the CWDM wavelength. Optical spectrum analysis verified clean channel separation with negligible crosstalk. Internal DOM telemetry provides real-time tracking for operating temperature, supply voltage, laser bias current, and optical launch/receive power. After a 48-hour continuous line-rate soak test, zero uncorrectable FEC errors were registered. A top-tier optical solution for enterprise architectures.
