MPO 12F APC (Female) to MPO 12F APC (Female) OS2 type B patch cables

1. Product Overview

The MPO-12 APC to MPO-12 APC OS2 Single Mode Patch Cable is designed for high-density fiber connectivity in data centers and telecommunications environments. This "Type B" (Cross-over) polarity cable is specifically used to connect two active devices (such as 40G/100G transceivers) or to link high-speed backbone trunking.

3. Key Features

High-Density Connectivity: 12 fibers in a single compact MPO connector, significantly reducing cable bulk.
APC Polish: The 8-degree angled polish ensures superior return loss performance, minimizing back-reflection for sensitive single-mode lasers.
Type B Polarity: Designed for direct connection between high-speed transceivers (e.g., QSFP+ to QSFP+).
LSZH Jacket: Environmentally friendly material that emits low smoke and zero toxic halogen gases in the event of fire.
Plug & Play: Factory-terminated and tested for immediate deployment and reliability.

4. Product Applications

A. Data Center High-Speed Networking

Specifically used for interconnecting 40G QSFP+ PLR4 or 100G QSFP28 PSM4 transceivers. The Type B polarity ensures that the transmit (Tx) fiber at one end matches the receive (Rx) fiber at the other.

B. Backbone Trunking

Ideal for connecting MPO cassettes in high-density fiber distribution frames (FDF), allowing for rapid scaling of network infrastructure without the need for individual fiber splicing.
