SM OS2 9/125um 48F(4×12) MTP-MTP trunk cable
This 48-fiber single-mode trunk cable consists of four independent 12-fiber MTP groups, constructed with low-loss OS2 9/125μm single-mode fiber and high-precision MTP UPC/APC connectors. Designed for high-capacity backbone transmission, it delivers stable low attenuation and high return loss for long-distance parallel optical links.
The yellow LSZH jacket complies with CPR Dca fire standard, featuring bend-insensitive fiber to prevent signal loss during dense rack routing. Compatible with 100G/400G/800G LR4/FR4 transceivers, it supports kilometer-level DCI and campus backbone connections.
All trunks undergo full IL/RL optical testing. Custom polarity, male/female pins, cable lengths and pull tabs are optional. Ideal for hyperscale data center main distribution frames and cross-floor interconnections.

Pre-terminated MPO Technology-Polarity （12C MT Ferrule）
Polarity defines the directional correspondence between the transmit (Tx) port and receive (Rx) port of optical fiber links. It standardizes the signal transmission direction of fiber connections and guarantees accurate and effective end-to-end signal interconnection in optical cabling systems.

Custom Pulling Eye.
The pulling eye safeguards MPO trunk connectors throughout cable laying and dismantling processes, especially in confined or inaccessible installation areas, by completely shielding the fiber breakout section and diverting tensile stress from the cable assembly to the protective sleeve.
