32F 4×MPO-12/APC Elite Male to 4×MPO-12/APC Elite Male Type B Single-Mode Fiber Assembly

1. Product Title

32F 4×MPO-12/APC Elite Male to 4×MPO-12/APC Elite Male Type B Single-Mode Fiber Assembly

2. Product Overview

The GracyFiber 32F 4×MPO-12/APC Elite Male to 4×MPO-12/APC Elite Male fiber assembly is a compact single-mode multi-fiber interconnect designed around four 8-fiber groups, providing 32 active fibers in total. Each end uses four MPO-12/APC male interfaces, with eight active fiber positions per connector and a defined Method B polarity arrangement.

3. Key Features

• 32-fiber single-mode configuration, arranged as four 8-fiber groups
• 4× MPO-12/APC Elite Male connectors on each end
• G657A1 single-mode fiber
• Ø0.6 mm loose-tube fiber construction
• Method B polarity with defined multi-fiber routing
• Insertion loss ≤0.35 dB
• Return loss ≥60 dB
• 8° ±0.2° APC end-face polishing angle
• Both connector ends configured as Key Up
• Nominal assembly length of 500 mm (+50/-0 mm)

4. Applications

Typical applications for this 32F MPO/APC fiber assembly include:

• 400G DR4 / DR4+ parallel optical interconnect
• 100G PSM4 optical interconnect
• High-speed optical transceiver testing
• Silicon photonics and optical engine connectivity
• AI data center optical interconnect
• Optical switch and optical test systems
• Internal equipment fiber routing
• High-density parallel single-mode fiber connectivity

For DR4, PSM4 or other parallel-optics applications, the equipment-side fiber lane assignment should be checked against the specific Type B / shuffle routing before deployment.

5. Technical Specifications

The following specifications are taken from the supplied product drawing. The document identifies 1310 nm and 1550 nm as test wavelengths, rather than defining the complete operating wavelength range.

Supplied Test Data

A separate test report identifies the assembly as a 4×8F MPO/APC(M) to 4×8F MPO/APC(M), SM G657A1, 0.5 m, Type B configuration and records channel-level insertion-loss and return-loss measurements for the XA, XB, XC and XD groups.

The listed measurements remain within the specified IL/RL limits, including individual channel readings across the four input/output groups.
