Bidirectional SFP Gigabit Fiber Transceivers

The DEM-330T/330R and DEM-331T/331R Bidirectional Gigabit SFP Fiber Transceivers are external transceivers designed for insertion in SFP (Small Form-Factor Pluggable) slots of network devices for transmission and reception of data signals on the ﬁber cables. These transceivers provide the Gigabit operation and physical compactness to deliver the speed, reliable long-distance data transfer, and deployment ﬂexibility that today’s ﬁber networks require.

Ideal for Long Distance Application

The DEM-330T/330R and DEM-331T/331R transceivers can be used to connect together switches, servers and ﬁber modules on a campus or metropolitan area network (MAN). Providing up to 10 km (DEM-330T/330R) or 40 km (DEM-331T/331R) of ﬁber cable distance, these highly integrated transceivers offer low jitter performance for extended optical link support without any degradation in performance.

Reliable Transmission

The DEM-330T/330R and DEM-331T/331R transceivers combine transmitting and receiving signals onto one ﬁber strand using two wavelengths. These transceivers are used in pair. At one end, one transceiver uses one wavelength to transmit and a second wavelength to receive. At the other end, the other transceiver ﬂips that relationship.

TRANSCEIVER

Standard Compliance

The DEM-330T/330R and DEM-331T/331R transceivers use standard simplex LC connectors for ﬁber cable connection. They conform to industry standards and are interoperable with D-Link Gigabit switches. Hotswap capability allows network administrators to plug or unplug them from the SFP slots without having to turn off the power of the connected device.

Durable

The DEM-330T/330R and DEM-331T/331R transceivers are packed in a Small Form Pluggable (SFP) metal housing to increase durability.
