Product Introduction

The B1-XPSM1315K-SC 10G SFP+ BiDi Optical Transceiver is designed for high-speed Gigabit optical communication over single-mode fiber.
It supports data rates up to 11.3Gb/s, making it suitable for 10 Gigabit Ethernet network applications.
The BiDi technology enables both transmit and receive signals to operate over a single fiber strand, helping reduce fiber infrastructure requirements.
It provides a transmission distance of up to 10 km over G.652 Single-Mode Fiber (SMF).
The transceiver utilizes 1270nm and 1330nm wavelengths for bidirectional optical transmission and reception.
A single SC optical connector provides a robust and convenient connection for fiber optic networks.
The module supports Digital Diagnostic Monitoring (DDM/DDMI) for real-time monitoring of key operating parameters.
Its hot-pluggable SFP+ form factor allows installation or replacement without shutting down compatible network equipment.
With power consumption of approximately 1W or less, the module provides an energy-efficient solution for 10G optical connectivity.
Designed in compliance with IEEE 802.3ae and SFP+ industry standards, it is suitable for enterprise, telecom, surveillance, and high-speed fiber network applications.

Functions

BiDi Single-Fiber Transmission

BiDi technology uses different wavelengths for transmitting and receiving data, allowing bidirectional 10Gbps communication over only one single-mode fiber strand. This helps reduce fiber cable requirements compared with conventional dual-fiber SFP+ connections.

Digital Diagnostic Monitoring (DDM/DDMI)

The built-in digital diagnostic function enables compatible network equipment to monitor important transceiver operating parameters, including:

• -Module Temperature
• -Supply Voltage
• -Tx Bias Current
• -Tx Optical Output Power
• -Rx Optical Input Power

This function helps network administrators monitor optical link conditions and simplify troubleshooting and preventive maintenance.

Hot-Pluggable Operation

The SFP+ module supports hot-plug capability, allowing the transceiver to be inserted or removed from compatible SFP+ equipment without powering down the system.

Loss of Signal (LOS) Monitoring

The module provides an Rx Loss of Signal (LOS) indication, enabling compatible equipment to detect optical signal loss and assist in network fault identification.

Low Power Operation

With power consumption of approximately 1W or less, the transceiver is suitable for high-density network equipment where power efficiency and heat management are important.

Typical Connection

10G Ethernet Switch / SFP+ Port
→ B1-XPSM1315K-SC BiDi SFP+
→ Single-Core Single-Mode Fiber (SC)
→ 10 km Maximum
→ Matching BiDi SFP+ Transceiver
→ 10G Ethernet Switch / Network Equipment

Important: BiDi transceivers must be used as a matched wavelength pair. One side transmits at 1270nm and receives at 1330nm, while the opposite side transmits at 1330nm and receives at 1270nm.
