Product details
Overview
AFBR-710DMZ from Broadcom (formerly Avago) is a hot-pluggable SFP+ optical transceiver supporting dual-rate 10.313 GBd (10GBASE-SR/SW) and 1.25 GBd (1000BASE-SX) operation over multimode fiber using an 850 nm VCSEL transmitter and PIN photodiode receiver. It delivers -4.3 dBm typical OMA output power, -7.5 dBm stressed sensitivity, and full digital diagnostics per SFF-8472. Designed for high-port-density 10GbE switches and routers.
For engineers reviewing the AFBR-710DMZ datasheet, pinout, applications, or equivalent options, key selection criteria include IEEE 802.3ae/802.3z compliance, Class 1 eye safety certification, SFF-8431/8432 mechanical compatibility, real-time Tx_Bias/Tx_Power monitoring, and hardware/software rate select via RS0/RS1 pins.
Technical Context
The AFBR-710DMZ implements a dual-rate architecture with independent TX/RX rate control via hardware pins (RS0/RS1) or software (A2h page EEPROM), enabling seamless transition between 10GBASE-SR and 1000BASE-SX modes. Its transmitter uses an Avago-designed 850 nm VCSEL in a TOSA with integrated laser safety circuitry that disables output on over-power detection.
The receiver employs a custom PIN-based ROSA with transimpedance amplifier and post-amplifier/quantizer IC, delivering CML outputs compliant with SFF-8431. Digital diagnostics use a two-wire interface (SCL/SDA) accessing A0h (SFF-8431) and A2h (SFF-8472) memory maps for real-time monitoring of Vcc, temperature, Tx_Bias, Tx_Power, and Rx_Power.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SFP+ transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-710SMZ | Same optical specs but rated for 0–70°C case temperature (vs. -40–85°C for AFBR-710DMZ); no extended temp qualification | Targeted at commercial datacom equipment; not validated for industrial ambient extremes | Select AFBR-710DMZ when operating outside 0–70°C or requiring full industrial temp range support |
| AFCT-739DMZ | 10GBASE-LR single-mode variant (1310 nm, 10 km reach); different wavelength, fiber type, and optical budget | Used in metro/access networks over SMF; incompatible with MMF infrastructure | Choose AFBR-710DMZ only for multimode fiber deployments ≤300 m; AFCT-739DMZ required for SMF links |
Compared with AFBR-710SMZ, the AFBR-710DMZ provides verified operation down to -40°C and up to +85°C, making it suitable for uncontrolled environments. Against AFCT-739DMZ, it trades reach and fiber type for lower cost and power in short-reach MMF applications-no electrical or mechanical compatibility exists between the two.

FAQ
What data rates does the AFBR-710DMZ support, and how is rate selection implemented?
The AFBR-710DMZ supports both 10.313 GBd (10GBASE-SR/SW) and 1.25 GBd (1000BASE-SX). Rate selection is implemented via hardware pins RS0 and RS1 (contact 7 and 9), or through software access to the A2h page of the EEPROM. When RS0 and RS1 are both high, the module operates at 10GBASE-SR; when both low, it operates at 1000BASE-SX. The AFBR-710DMZ also supports mixed-rate configurations where TX and RX operate at different speeds.
Is the AFBR-710DMZ compliant with Class 1 laser safety requirements?
Yes, the AFBR-710DMZ is certified Class 1 eye safe per IEC 60825-1 and US FDA CDRH requirements. It incorporates an active eye safety circuit that continuously monitors optical output power and disables the VCSEL transmitter within microseconds if the Class 1 limit is exceeded. Certification documentation includes CDRH No. 9720151-128 and TUV file R 72121699.
Does the AFBR-710DMZ require external AC coupling capacitors or termination resistors on the host board?
No, the AFBR-710DMZ integrates AC coupling capacitors and 100 Ω differential termination for its CML high-speed interfaces (TD+/TD-, RD+/RD-), per SFF-8431 specification. Host board designs need only route controlled-impedance traces; no external components are required for signal integrity. This reduces BOM cost and layout complexity while ensuring compliance.
What digital diagnostic functions are supported by the AFBR-710DMZ, and how are they accessed?
The AFBR-710DMZ supports full SFF-8472 digital diagnostics including real-time monitoring of Tx_Bias, Tx_Power, Vcc, temperature, and Rx_Power via the two-wire interface (SCL/SDA) at address 0xA2. These values are accessible through the host's I²C master controller. Diagnostic capabilities enable Predictive Failure Identification, Compliance Prediction, Fault Isolation, and Component Monitoring-all implemented within the AFBR-710DMZ firmware and memory map.
What is the operating temperature range for the AFBR-710DMZ, and how is it specified in the datasheet?
The AFBR-710DMZ has an absolute maximum case operating temperature range of -40°C to +85°C (Table 3), with recommended operating conditions specified as 0°C to +70°C (Table 4). The wider absolute rating validates suitability for industrial and outdoor deployments, while the recommended range reflects conditions under which all optical and electrical specifications are guaranteed. Thermal validation was performed per Figure 7 reference point on the module case.
