The correct answer isOptiXtrans DC908 is 2U high, which is able to install in 600mm deep rack.

Here's an analysis of each option:

A . OptiXtrans DC908 cannot be managed by NCE:This is incorrect. The DC908 is fully compatible with Huawei'sNCE (Network Cloud Engine)for centralized management, monitoring, and automation.

B . OptiXtrans DC908 is 2U high, which is able to install in 600mm deep rack:This is correct. The DC908 has a compact2U form factor, making it ideal for space-constrained environments. Its shallow depth (compatible with 600mm racks) ensures flexibility in deployment, especially in data centers and edge locations.

C . OptiXtrans DC908 can support L2 function:This is incorrect. The DC908 primarily focuses on Layer 1 (physical layer) and Layer 0 (optical layer) transport, such as OTN and WDM. It does not natively support Layer 2 (data link layer) functions like switching or routing.

Campus OptiX (POL) delivers significant value to customers through the following key benefits:

Simple Architecture:POL simplifies network design by using a single fiber infrastructure to deliver multiple services (voice, data, video), reducing complexity and cost.

Smart O&M:With centralized management tools like eSight, POL enables efficient monitoring, troubleshooting, and automation of network operations.

Easy to Evolve:POL supports future-proof technologies like XG-PON and NG-PON2, allowing seamless upgrades to higher bandwidths.

High Reliability:The passive nature of POL (no active components in the ODN) ensures high reliability and low maintenance requirements.

These advantages make POL an attractive solution for enterprise campuses and other large-scale deployments.

POL Deployment Best Practices

TheFlex-PON boardsupports multiple PON technologies, including:

GPON:Gigabit Passive Optical Network, widely used for residential and small business applications.

XG-PON:10G Asymmetric Passive Optical Network, offering higher upstream and downstream bandwidths.

XGS-PON:10G Symmetric Passive Optical Network, providing equal upstream and downstream speeds.

Combo PON:Combines GPON and XG(S)-PON on the same port, enabling seamless upgrades from GPON to XG(S)-PON without replacing hardware.

The only option not supported by Flex-PON isXG-PON Combo, as 'Combo' typically refers to the integration of GPON and XG(S)-PON, not just XG-PON alone.
