Yokogawa LS38-C3S-TI-N-GD Fiber Optic Transceivers

The Yokogawa LS38-C3s-TI-N-GD, also cataloged as the LS38-C3s-TI-N-GD Fiber Optic Transceiver Module, operates as a dedicated hardware component for high-speed serialized data transmission and optical media conversion within industrial networks. Housed in a standard Small Form-Factor Pluggable (SFP) chassis, this hot-pluggable transceiver provides direct physical execution by converting high-frequency electrical backplane signals into light pulses for long-distance communication over single-mode optical fiber lines.

Hardware Specifications

Serialization Logic and Optical Attenuation Thresholds

The LS38-C3s-TI-N-GD manages optical carrier modulation to maintain baseline transmission stability metrics, processing serialized differential data frames from 1063 to 1250 Mb/s without clock jitter or packet propagation drift. The transmitter block utilizes a 1310 nm Fabry-Perot (FP) laser diode to launch continuous digital light pulses down 9/125 um single-mode fiber cores, while the receiver block employs an integrated PIN photodiode to parse incoming optical signals. To safeguard internal electronics against data loss or saturation, the module operates within a strict 10.5 dB optical link budget; exceeding the -20 dBm receiver sensitivity limit triggers immediate signal degradation, while exceeding the -3 dBm saturation point can overload the PIN photodiode array.

Frequently Asked Questions

Q: What operational faults occur if the optical input power arriving at the LC Duplex connector exceeds -3 dBm?

A: An optical signal stronger than -3 dBm will saturate the internal PIN photodiode. This causes carrier over-saturation and increases bit error rates (BER), potentially over-driving the optical receiver circuit and leading to permanent hardware damage.

Q: Can the LS38-C3s-TI-N-GD module operate over Multi-Mode Fiber (MMF) lines for shorter distances?

A: This module is engineered specifically for 1310 nm single-mode fiber (9/125 um). MMF cables have larger core diameters (50 um or 62.5 um) that introduce severe modal dispersion at this wavelength, resulting in high optical loss, timing jitter, and link dropouts.
