Product details
Overview
AFBR-710ISMZ from Broadcom (formerly Avago) is a hot-pluggable SFP+ optical transceiver for 10GbE Ethernet, implementing IEEE 10GBASE-SR/SW over multimode fiber using an 850 nm VCSEL transmitter and PIN photodiode receiver. It operates across -40 °C to +85 °C case temperature, delivers ≤ -4.3 dBm OMA output power, and supports 300 m reach on OM3 MMF in high-port-density switches and routers.
For engineers reviewing the AFBR-710ISMZ datasheet, pinout, applications, or equivalent options, this page provides verified technical context, digital diagnostic interface behavior, SFF-8431/8472 compliance details, EMI performance margins, and real-world deployment constraints for industrial-grade 10G optical interconnects.
Technical Context
The AFBR-710ISMZ implements a fully integrated SFP+ transceiver architecture with separate transmitter and receiver signal paths: the VCSEL-based TOSA drives differential CML input (TD±) at 10.3125 GBd, while the ROSA delivers differential CML output (RD±) with built-in AC coupling and 100 Ω termination requirement. Its two-wire serial interface (SCL/SDA) accesses both legacy EEPROM (0xA0) and diagnostic memory (0xA2), enabling real-time monitoring of Tx_Bias, Tx_Power, Vcc, temperature, and Rx_Power per SFF-8472.
Electrical compliance follows SFF-8431 for high-speed signaling and low-speed control logic (LVTTL), with TX_DISABLE and RX_LOS implemented as open-collector outputs requiring host-side pull-ups. The module's metal housing and shielded design meet FCC Class B, EN55022 Class B, and VCCI Class A EMI requirements when used with SFF-8432-compliant cages-critical for dense 1U switch deployments.

FAQ
What is the maximum supported link distance for AFBR-710ISMZ on OM4 multimode fiber?
The AFBR-710ISMZ supports up to 400 meters on OM4 multimode fiber, as specified in IEEE 802.3ae 10GBASE-SR and confirmed in the official datasheet Table "Link lengths at 10.3125 GBd". This assumes compliant OM4 fiber with ≤ 3.5 dB/km attenuation and proper connector cleanliness-actual reach may decrease with higher modal dispersion or substandard cabling. The AFBR-710ISMZ does not support longer distances on single-mode fiber.
Does AFBR-710ISMZ support SFF-8472 digital diagnostics, and which parameters are accessible?
Yes, the AFBR-710ISMZ fully supports SFF-8472 digital diagnostics via its two-wire interface (SDA/SCL) accessing memory address 0xA2. Real-time monitored parameters include transmitter bias current (Tx_Bias), transmitted optical power (Tx_Power), supply voltage (Vcc), case temperature, and received optical power (Rx_Power), along with status flags for TX_FAULT and RX_LOS-all documented in the datasheet Section "Digital Diagnostic Interface".
Can AFBR-710ISMZ be used in hot-plug applications, and what mechanical specifications ensure reliability?
Yes, the AFBR-710ISMZ is explicitly designed for hot-plug operation: it complies with SFF-8432 Improved Pluggable Formfactor and can be inserted or removed while the host system is powered on. Its metal housing makes initial contact with the SFP+ cage to mitigate ESD risk, and the MOD_ABS pin signals presence/absence to the host controller-ensuring safe enumeration and power sequencing per SFF-8431 Section 4.3.
What is the optical output power specification for AFBR-710ISMZ, and how is it measured?
The AFBR-710ISMZ specifies a minimum optical modulation amplitude (OMA) of -4.3 dBm, measured per IEEE 802.3ae Clause 52. This value is not peak power but the difference between average power of logical '1' and '0' bits, ensuring sufficient signal-to-noise ratio for 10GBASE-SR compliance. The actual OMA varies with center wavelength and spectral width per Table 9 in the datasheet, and must remain within Class 1 laser safety limits.
How does the AFBR-710ISMZ implement eye safety, and what certifications apply?
The AFBR-710ISMZ implements hardware-enforced Class 1 eye safety per IEC 60825-1 and US FDA 21 CFR Part 1040.10, with continuous monitoring of optical output power. If unsafe emission levels are detected-due to internal fault or host-induced Vcc fluctuation-the transmitter is disabled immediately. It holds CDRH Certification No. 9720151-128 and TUV file R 72121699, both referenced in the official datasheet Table 1.
