A 1x4 fiber optic splitter is a passive optical device used in fiber optic networks to split a single input fiber into multiple output fibers. It is commonly used in applications like FTTH (Fiber To The Home) networks, telecom, and broadband services to distribute optical signals.
Here’s a general product specification for a 1x4 fiber optic splitter
General Description
Product Type: 1x4 Fiber Optic Splitter
Function: Splits a single optical signal into four output signals
Application: Optical networks, fiber-to-the-home (FTTH), telecom, data centers, and CATV
Technology: Planar Lightwave Circuit (PLC) or Fused Biconical Taper (FBT)
Characteristics
Split Ratio Accuracy: ±5% (actual power split between output ports)
Environmental Stability: High stability in temperature and humidity ranges
Cross-Talk: Low (< -60 dB) to avoid signal interference between output ports
Insertion Loss Variation: ≤ 0.5 dB across all outputs
Reliability: Long service life (minimum 25 years under standard conditions)
Physical Specifications
Input/Output Fiber Type: Single-mode fiber (SMF-28), or MMF (OM1/OM2/OM3) depending on application
Connector Options: SC, LC, ST, MTP/MPO, or bare fiber (other connectors available upon request)
Package Type: Cassette, tray, or module-based design depending on deployment needs

Performance Standards
Compliance:
RoHS (Restriction of Hazardous Substances)
IEC 61300 (International Standard for Optical Fibre Components)
Telcordia GR-1209-CORE and GR-1221-CORE (for reliability and environmental testing)
Specifications
