Q: What is a 1G SONET/SDH Transceiver?
A: A 1G SONET/SDH transceiver is a precisely developed transceiver module designed for bidirectional data transmission at gigabits per second (1G) over Synchronous Optical Network (SONET) or Synchronous Digital Hierarchy (SDH) networks. Walsun’s industry-standard SFP interface converters, suitable for Packet-Over-SONET/SDH, optical networking, and ATM applications, are hot-pluggable optical interfaces connecting multiple router interface ports. These ports are capable of supporting OC-3, OC-12, and OC-48 data rates in both single-mode and multi-mode applications for short, medium, and long distances.
Q: What types of SFP optical modules are there?
A: SFP optical modules are compact, hot-pluggable transceiver devices widely used in the telecommunications industry, coming in various forms such as BIDI-SFP, Ethernet SFP, CWDM SFP, DWDM SFP, and SFP+ modules. Additionally, compared to similar modules like XFP, X2, and XENPAK, SFP modules not only provide direct compatibility but are also characterized by a generally lower cost.
Q: What is an SFP optical module?
A: An SFP optical module features a hot-pluggable small form-factor design, with current maximum speeds reaching up to 10G and commonly utilizing LC connectors. SFP stands for Small Form-factor Pluggable, essentially an upgraded version of GBIC. The SFP optical module occupies half the space of a GBIC module, enabling twice as many ports to be configured on the same panel.
Q: What components make up an SFP optical module?
A: An SFP optical module consists of a laser diode, a PCB IC, and external components, which include the housing, release mechanism, latches, base, pull tab, rubber dust cap, and the printed circuit board assembly (PCBA). The color of the pull tab aids in identifying the module’s parameter type.
