1000BASE SFP SR(850nm 550M) OSFP-108505
Transmitters and Receivers
O-send
Emission wavelength: 850nm Specification: 550m
This enhanced SFP transceiver includes DDM and meets Ethernet requirements for 1.25Gbps communications. Alarms/warnings follow SFF-8472 MSA version 10.4 through I2C. It supports 1.25G at 850nm over up to 550m of multimode fiber. Subwatt consumption and excellent EMI enable dense ports. RoHS compliance and industry safety design/testing include Class I laser conformity with US FDA/CDRH and IEC-60825. The SFP SR connects to a standard 20-contact SFP connector for hot swapping, allowing maintenance/configuration without host power removal. Transmit/receive DATA interfaces are internally AC-coupled. LV-TTL transmitter-disable input and LOS output are provided. A pull-ring latch enables easy release and meets SFP MSA. A +3.3V supply supports case temperatures 0°C to +70°C commercial or -40°C to +85°C industrial. A metal housing shields EMI.

1000Base SFP BIDI Module(1310nm/1550nm 20Km) OSFP-1131520
Transmitters and Receivers
O-send
Emission wavelength: 1310nm/1550nm Specification: 20KM
This enhanced small-form-factor pluggable (SFP) fiber transceiver includes digital diagnostic monitoring (DDM). It complies with Ethernet standards and is ideal for 1.25Gbps data communications. DDM alarms and warnings are integrated through an I2C serial interface under the SFF-8472 multisource agreement (MSA), version 10.4. The transceiver supports 155Mbps to 1.25Gbps and provides a solution for 1310nm transmission over up to 20 kilometers of single-mode fiber. Subwatt consumption and excellent EMI performance support high port density. It is RoHS compliant and designed and tested to industry safety standards, and is a Class I laser product under US FDA/CDRH and international IEC-60825 standards. The SFP LR connects to a standard 20-contact SFP connector for hot swapping, allowing configuration changes or maintenance by replacing the transceiver without switching off the host. Transmitter and receiver DATA interfaces are internally AC-coupled. An LV-TTL transmitter-disable input and loss-of-signal (LOS) output are provided. A bail latch permits easy module removal and complies with the SFP MSA. A single +3.3V supply powers operation at case temperatures of 0°C to +70°C commercially or -40°C to +85°C industrially. The metal case protects against electromagnetic interference.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
