About the Finisar FTRJ1421SH
The Finisar FTRJ1421SH (now a Coherent Corp. product, formerly II-VI) is a SFF 2x10 OC-48 IR-1 multirate (2.67G), non-RoHS (PN as indexed; may be truncated) optical transceiver for up to 2.67 Gb/s links at 1310nm over SMF, with reach up to 15km. It belongs to Finisar's FTRJ1421S family, which has 4 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
- Up to 2.67Gb/s bi-directional data links
- Standard 2x10 pin SFF footprint (MSA compliant)
- Uncooled 1310nm DFB laser transmitter
- Duplex LC connector
- Single 3.3V power supply
- Low power dissipation <700 mW typical
FTRJ1421SH: frequently asked questions
What is the Finisar FTRJ1421SH?
The FTRJ1421SH is a Finisar SFF 2x10 transceiver for OC-48 IR-1 multirate (2.67G), non-RoHS (PN as indexed; may be truncated) at up to 2.67 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
What is the maximum distance of the FTRJ1421SH?
The FTRJ1421SH is specified for up to 15km over SMF. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
What is the optical power budget of the FTRJ1421SH?
Per the Finisar family datasheet, the FTRJ1421SH transmits −5 to 0 dBm and has a receiver sensitivity of −18 dBm @ OC-48; −21 dBm @ 2x FC; −22 dBm @ GbE and OC-12; −23 dBm @ OC-3. Maximum receiver input is 0 dBm (upper bound of sensitivity-row range; −10 dBm @ OC-3).
Which fiber and connector does the FTRJ1421SH use?
The FTRJ1421SH works at 1310nm over SMF. Both ends of a link must use the same optical standard.
Will the FTRJ1421SH work in my Cisco, Juniper, Arista or HPE switch?
The FTRJ1421SH follows the SFF 2x10 MSA, so it fits any matching port. It carries Finisar's own EEPROM programming; switches that check the module vendor may need a configuration setting or a vendor-branded optic. Send us your switch model and we confirm before dispatch.
FTRJ1421SH vs FTRJ1421SG: what is the difference?
Both are in Finisar's FTRJ1421S family and share the same core optics; the suffix marks a different build option (latch, receiver or ordering variant). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTRJ1421SH part number mean?
The FTRJ prefix marks Finisar's earlier-generation SFP / SFF family. The remaining characters identify the optical design and build variant.
Is the FTRJ1421SH still available?
The FTRJ1421SH is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTRJ1421SH price in India and how do I order?
The Finisar FTRJ1421SH price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in for a GST quote.
What power does the FTRJ1421SH need?
It runs from 3.3 V (3.00–3.60 V) with power dissipation of <700 mW typical (Icc 200–300 mA).
