The term "male" or "female" is typically used to describe the gender of connectors, and in the context of networking transceivers like Cisco's QSFP 100G SR4, it's not applicable in the same way.

The Cisco QSFP 100G SR4 is a transceiver module that plugs into a QSFP (Quad Small Form-factor Pluggable) port on a networking device, such as a switch or a router. The QSFP module itself has a plug with multiple pins (male pins), and it is designed to be inserted into the QSFP port on the networking equipment.

Therefore, you might hear terms like "plug" and "port" instead of "male" and "female" when referring to connectors and transceivers. The QSFP module has a plug, and the QSFP port has a receptacle to accept the plug. In the case of the Cisco QSFP 100G SR4, the transceiver is designed to work with QSFP ports on Cisco networking equipment that supports 100 Gigabit Ethernet connections over multimode fiber.
