SFP transceiver BlueOptics SFP-503-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-503-BO is a Small Form-factor Pluggable (SFP) fiber optic transceiver designed for single-mode networks. It supports a maximum data rate of 1250 Mbit/s at a wavelength of 1310 nm and uses an LC duplex connector for bidirectional optical transmission. The module is housed in metal, operates from a 3.3 V input, and weighs approximately 3 g, offering a compact solution for gigabit-class links over single-mode fiber.

Advantages

This SFP module conforms to MSA SFP mechanical and electrical standards and is compatible with systems that accept the Gigamon SFP-503 1000BASE-LX form factor. Built with industry-grade optical and electronic components, the transceiver supports reliable long-distance single-mode transmission and provides low power operation at 3.3 V. The metal housing offers mechanical durability and EMI shielding, while the lightweight design simplifies hot-swap handling and installation in switches, routers and other compatible hardware.

Suitable for

• Single-mode fiber uplinks between network devices
• Switch-to-switch or switch-to-router connections
• Storage and server connectivity requiring 1.25 Gbit/s optical links
• Long-distance links up to typical 10 km range when used with appropriate fiber

Key specifications

• Weight: approx. 0.003 kg

How to use

Install the BlueOptics SFP-503-BO by inserting the module into a compatible SFP socket on a switch, router or other networking device while the device is powered according to the vendor's hot-swap guidelines. Connect an LC duplex single-mode fiber patch cable to the transmitter and receiver ports ensuring correct polarity. Verify link status and negotiated speed on the host device; the transceiver supports 1.25 Gbit/s operation and common protocols such as Ethernet and Fibre Channel over appropriate hardware. If the host device supports digital diagnostics (DDM/DOM), enable and monitor supplied parameters like optical power and temperature through the device management interface.

Recommendations

For reliable performance, pair the SFP-503-BO with single-mode LC duplex patch cords and use appropriate patch panels or adapters. Confirm host compatibility with Gigamon SFP-503 style modules if the platform enforces vendor checks. When using DDM/DOM features, ensure the host supports SFF-8472 to access live diagnostic data for proactive link maintenance.
