Complies with IEEE 802.3 & 802.3u standards. 10/100Mbps Auto Negotiation. Auto cross over on RJ45 port.  Support Switching mode and Pure Converter mode. Support Link-Cross-Check. Auto or manually select 10 or 100 speed and Half or Full Duplex mode. Strong metal case design. LED indicators for status check and trouble shooting.

GC-H21SC is designed to meet the needs for optical fiber network deployment for extending a copper based network via fiber cables.  It is a 10/100Mbps Auto-Negotiation Fast Ethernet Switching Media Converter to provide conversion between 10Base-T Ethernet or 100Base-TX Fast Ethernet UTP (Cat.3 or Cat. 5) cables and 100Base-FX multimode (SC connectors) fiber optic cables.

As defined in IEEE 802.3 & 802.3u standards, 10Base-T & 100BaseTX specify the transmission over category 3 or 5 cables media can transmit signals up to 100 meters.  100Base-FX specifies the transmission in multimode fiber media can transmit signals up to 2 kilometers and transmit even longer distance in single-mode fiber medias.

GC-H21SC comes with one RJ45 connector with Auto Cross Over feature to connect to a 10 or 100Base-TX device such as workstation, hub or switch, etc. via Cat.5 copper cables and one SC connector to connect to a 100Base-FX multi-mode fiber device via  50/125, 62.5/125 or 100/140um multimode fiber cables.  GC-H21SC will convert the signals between these two different types of cables.

The GC-H21SC is a slim and compact unit with strong metal case.  It features 6 status LEDs for easy diagnostics and trouble shooting.
