ZyXEL SFP-SX-D SFP 1000Mbit/s 850nm Multi-mode

GbE Fiber Transceiver, LC, 850 nm, 0.55 km/ 601 yd <b>Reliable Transceiver Modules for Different Connectivity Demands</b>

The ZyXEL Transceiver Series is a complete range of industry standard, hot-pluggable transceiver modules consists of Fast, Gigabit and 10 Gigabit variations.

<b>Standard-based design assures compatibility</b>
The ZyXEL transceiver family follows industry standards to assure compatibility with switches from other manufacturers without barrier set by proprietary technologies.

<b>Comprehensive portfolio for different connectivity demands</b>
With ZyXEL’s comprehensive Fast, Gigabit and 10 Gigabit transceiver product range, also Direct Attached Cable 1M /3M, users can just plug the proper model onto the network to extend the physical coverage.

<b>Hot-swappable design facilitates network maintenance</b>
Independent transceiver design provides the highest network maintenance flexibility. Transceivers can be freely added when required, and infrastructure upgrades or transceiver repairs can be done easily by just replacing the transceiver instead of the whole device.

<b>Bi-directional transceivers maximizes usage of existing fiber plant</b>
Traditional fiber optic networking requires two strands of fiber to accomplish communications, in which one strand is reserved for sending signals, while the other is for receiving. On the other hand, bi-directional, dual-wavelength transceivers can establish communications over just one strand of fiber by using two separate optical wavelengths: one receives and the other transmits signals. Transmission capacity can be expanded immediately without additional cost laying new fiber.

<b>Supporting Digital Diagnostics Monitoring Interface (DDMI) SFP enhances management capability</b>
The enhanced digital interface enables a real time link to be established between the switch and the SFP transceiver. This enables the switch to access operating parameters within the fiber link. This includes digital features such as soft control and monitoring of SFP I/O signals.
In addition, the DDMI functionality enables the capability to implement digital alarms and warnings.
This feature ensures that the business can be proactive in preventative maintenance of the network and ensure business continuity.

<b>DDMI Monitors:</b>

- Temperature
- Supply voltage
- Transmitted bias current
- Transmitted power
- Received power

All features listed above include alarm and warning thresholds.
