Copper Ethernet SFPs

SFP-GC-R and SFP-GA-R

Overview

MRV off ers two models of Ethernet SFPs that support Gigabit Ethernet functionality for copper media application.

The SFP-GC-R model supports Gigabit Ethernet with a 1000Base-T interface. It is designed for Layer 1 network devices

that do not incorporate an Ethernet MAC. The SFP-GA-R is designed for use in Layer 2 and higher protocol devices such

as switches and routers that do incorporate an Ethernet MAC. It supports Gigabit Ethernet with an auto-negotiating

1000Base-T interface. SFP-GC-R and SFP-GA-R models each support MDI/MDI-X auto-detection and jumbo packet sizes

9,600+ bytes.

Installed into MRV products with an available SFP port, the SFP-GC-R plug-ins provide a simple and cost-eff ective way

to merge copper and fi ber network segments.

The SFP-GA-R gives network administrators greater fl exibility in confi guring their SFP-enabled switches and routers,

allowing them to use less expensive copper cabling and interfaces for links of 100 meters or less.

The SFP-GC-R and SFP-GA-R do not convert between edge devices of diff erent speeds or duplex mode. Connected

edge devices must operate at the same speed and duplex mode to communicate. An edge device that supports auto-

negotiation may require specifi c interface settings for fi xed Gigabit Ethernet speed and duplex mode operation.

The SFP-GC-R uses the SFP’s RX_LOS pin for link indication. The SFP-GA-R is compatible with 1000Base-X autonegotiation,

but does not use the RX_LOS pin for link indication because RX_LOS is internally grounded. The SFP-GA-R and SFP-GC-R

SFPs support the 2-wire serial communication protocol outlined in the SFP MSA to communicate the link indication.

Application A: Gigabit Ethernet Copper-to-Fiber Conversion with Redundancy

SFP-GC-R SFPs are used in combination with the Fiber Driver Dual Multi-Rate Transponder

(EM316DMR3G-3R) to create edge-to-edge redundant Gigabit copper links.
