BLY · DTS / DAS / BOTDA / BOTDR · BLY sensing cables

Seven cable variants for distributed temperature, acoustic/vibration and combined temperature, vibration and strain sensing. Select by monitoring needs and installation environment.

01 · General-purpose Raman temperature cable

General-purpose Raman temperature cable

BLY-MM03P

Cable construction: 3.0 mm outer diameter; 62.5/125 μm germanium-doped multimode fiber for Raman temperature sensing; internal stainless-steel spiral armor; tensile strength at least 200 N.
Options and configurations: Optional 50/125 μm fiber and multicore construction with SM, MM or mixed fibers. PVC or LSZH sheath, with enhanced UV, tensile and crush resistance options. An explosion-protection solution meeting Ex op is IIC T6 Gb requirements is available as an option.
Applications: Fire-related temperature monitoring in cable trenches, cable floors, cable tunnels, lithium-battery warehouses, electrolytic cells, factories, halls and grain stores; highways, metro tunnels, coal mines and petrochemical pipelines.

02 · Corrosion-resistant armored temperature cable

Corrosion-resistant armored temperature cable

BLY-MM03P (AC corrosion-resistant)

Cable construction: 2–3.0 mm outer diameter; corrosion-resistant, high-temperature PTFE sheath, rated up to 350 °C depending on configuration; 62.5/125 μm germanium-doped multimode Raman temperature fiber; stainless-steel spiral armor; tensile strength at least 400 N.
Options and configurations: High-temperature or 50/125 μm fiber options; enhanced tensile and crush resistance; selectable temperature ratings from 150 to 350 °C; multicore SM, MM or mixed-fiber construction.
Applications: Corrosive, hot, toxic, high-UV, strongly acidic or alkaline environments where standard PVC or LSZH is unsuitable and internal metal reinforcement is permitted.

03 · All-dielectric corrosion-resistant temperature cable

All-dielectric corrosion-resistant temperature cable

BLY-MM03P (AC corrosion-resistant)

Cable construction: 2–3.0 mm outer diameter; all-dielectric, metal-free construction with a corrosion-resistant, high-temperature PTFE sheath; 62.5/125 μm germanium-doped multimode Raman temperature fiber; Kevlar braid for tensile strength, bending resistance and low loss.
Options and configurations: Optional 50/125 μm or high-temperature fibers, multicore construction and enhanced tensile/crush resistance; SM, MM or mixed fibers.
Applications: Strong electromagnetic-interference environments. Metal-free construction avoids creepage and induced-current risks associated with metallic parts. Applications include high-voltage substations, nuclear power stations, large battery-storage systems, non-magnetic defense and aerospace installations, and harsh chemical, thermal or UV environments.

04 · High-strength Raman temperature cable (flame-retardant and fire-resistant)

High-strength Raman temperature cable (flame-retardant and fire-resistant)

BLY-MM03H

Cable construction: 62.5/125 μm germanium-doped multimode Raman temperature fiber; configurable 2.0–3.0 mm outer diameter; internal stranded steel-wire reinforcement; tensile strength at least 2,000 N; PVC or low-smoke zero-halogen LSZH sheath.
Options and configurations: Optional 50/125 μm fiber and multicore SM, MM or mixed-fiber construction; enhanced tensile, crush, bend and torsion resistance; custom PVC, LSZH or PTFE sheath.
Applications: Power, oil, coal mining, new energy and industrial installations with demanding tensile, torsional and bending requirements.

05 · High-sensitivity, low-loss DAS acoustic/vibration cable

High-sensitivity, low-loss DAS acoustic/vibration cable

BLY-SM02B

Cable construction: 3–5 mm outer diameter; 9/125 μm low-loss single-mode fiber for vibration sensing; optional reinforced construction.
Options and configurations: Multicore SM, MM or mixed fibers; enhanced tensile/crush resistance; PVC, LSZH or PTFE sheath; fence-mounted outdoor or direct-burial versions; custom vibration-sensing cavity structures matched to BLY DAS interrogators.
Applications: Perimeter security at airports, prisons and substations; vibration warning along oil pipelines, mine shafts and railways; monitoring in hazardous chemical or strong magnetic-interference environments; power-cable third-party damage detection and conveyor predictive maintenance.

06 · Buried and fence-mounted temperature/vibration/strain composite cable

Buried and fence-mounted temperature/vibration/strain composite cable

BLY-4B695-BL

Cable construction: 5–10 mm outer diameter; multiple fibers in one cable, with mixed SM and MM fibers; supports combined temperature, vibration and strain measurement with corresponding interrogators.
Options and configurations: Custom multicore SM, MM or mixed-fiber construction and enhanced tensile/crush resistance; PVC, LSZH or PTFE sheath; fence-mounted outdoor or direct-burial versions; compatible with BLY DTS, DAS, BOTDA and BOTDR interrogators.
Applications: Combined distributed temperature, vibration and strain monitoring for heating pipelines, dry oil wells, oil and gas lines, water and sewage pipelines, and power utility corridors.

07 · Flat surface-mounted temperature/vibration/strain composite cable

Flat surface-mounted temperature/vibration/strain composite cable

BLY-4B6B35-BL

Cable construction: Nominal 9 mm profile; drawing dimensions: 9.0±0.2 mm wide and 3.5±0.2 mm high. Multiple fibers in one cable with mixed SM/MM fibers; supports combined temperature, vibration and strain measurement with corresponding interrogators.
Options and configurations: A purpose-designed surface-mount profile conforms to curved pipelines for convenient installation and close contact.
