Description
The cable is made by the tight buffer fiber wrapped with a layer of aramid yarn as strength member units,multi fibers as the sub unit twist with FRP into the circle ,and finally into fiber optic cable with PVC or LSZH sheath,with dry-type water-blocking materials between fiber and sheath.
Features
– Each sub cable contains aramid yarn,good bend performance,without loose tube,cleaning friendly,easy construction and connection.
– Tight buffer fiber with single strength member and sheath to overcome the effect from bad environment and Mechanical stress.
– The low smoke and low halogen flame retardant sheath has the characteristics of fire prevention and self extinguishing, and is suitable for indoor environment such as computer room, cable shaft and indoor wiring.
– LSZH sheath,UV,Waterproof mildew,ESCR,No acid gas release,non-corrosive room equipment, suitable for indoor and outdoor use or need a high flame-retardant grades of the indoor environment (such as wiring in the ceiling, open wire cabling etc.)
Standards
– YD/T1258.2-2009
– ICEA-596
– GR-409
– IEC794
– the requirements of UL approval for OFNR and OFNP.

FAQ
Q1: What is the main structural design and application of the MPBC-B Break-out Cable?
A: The MPBC-B is a gel-free, high-core-count tight-buffered breakout cable designed for high-density indoor/outdoor cabling (e.g., data centers, machine rooms, cable shafts, and ceiling wiring). Each subunit consists of tight-buffered fibers reinforced with aramid yarn. Subunits are twisted around a central FRP strength member with dry water-blocking materials and encased in a flame-retardant PVC or LSZH sheath.
Q2: Which industry and fire-safety standards does the MPBC-B cable comply with?
A: The cable complies with YD/T 1258.2-2009, ICEA-596, GR-409, and IEC 60794 (IEC794) standards, as well as UL approval requirements for OFNR (Riser) and OFNP (Plenum) ratings.
Q3: What core capacities, dimensions, and weights are available for MPBC-B?
A: Standard core counts and specifications include:
- 24 Cores: 13.8 ± 0.5 mm outer diameter | 70 kg/km weight
- 48 Cores: 18.0 ± 0.5 mm outer diameter | 150 kg/km weight
- 96 Cores: 18.0 ± 0.5 mm outer diameter | 340 kg/km weight
Q4: What are the mechanical and environmental performance parameters?
A: Physical performance ratings include:
- Tensile Strength: 500 N long-term / 1300 N short-term
- Crush Resistance: 300 N/100mm long-term / 1000 N/100mm short-term
- Bending Radius: 30D static / 15D dynamic
- Temperature Range: -20℃ to +60℃ operating and storage temperature
Q5: Who manufactures the MPBC-B cable and how can I place an inquiry?
A: Manufactured by FirstFiber Technologies, the cable carries a reference price starting at $0.9 USD. You can select your desired core count, fiber type (G.652D, G.657A1/A2, OM1–OM5), sheath material (PVC/LSZH), and custom length on the product page, then click “Add to Quote” or “Request a Demo”.
