Functions

Table 3 describes functions of the card.

**Table 3** Functions
Function	Description
Basic functions	Provides four 40GE QSFP+ optical ports for data access and line-rate switching. Each 40GE port can be split into four 10GE ports.
Hot swapping	Supported
Service port stacking	Ports on the card can be used as stack ports. NOTE: A 40GE port cannot be used as a stack port after it is split into four 10GE ports.

1. Four 40GE QSFP+ optical ports

40GE QSFP+ optical port

A 40GE QSFP+ optical port sends and receives service traffic at 40 Gbit/s and can be split into four 10GE ports. After a split, the 40GE QSFP+ optical port needs to be connected to a remote device using a 1-to-4 QSFP+ fiber (with matching optical modules), a 1-to-4 QSFP+ AOC cable (applicable in V200R009C00 and later versions), or a 1-to-4 QSFP+ copper cable. Table 5 lists the attributes of a 40GE QSFP+ optical port.

All the optical ports on the card support only QSFP+ optical modules, QSFP+ AOC cables (applicable in V200R009C00 and later versions; 10 m; QSFP+ to QSFP+ or QSFP+ to 4*SFP+), and QSFP+ copper cables (1 m, 3 m, and 5 m; QSFP+ to QSFP+ or QSFP+ to 4*SFP+).

Attribute	Description
Connector type	LC/MPO
Optical port attributes	Depend on the optical module used (see 40GE QSFP+ Optical Modules)
Standards compliance	IEEE 802.3ba
